The most common drilling machine can be considered the one that is made of ordinary or electric drill. In such a drill machine, you can accommodate both stationary and make it removable. In the first case, the power button can be transferred to the drilling machine for greater convenience, in the second - drill can be removed and used as a separate tool.

Components for homemade drilling machine:

• Drill;
• Base;
• Rack;
• Fastening a drill;
• Mechanism feed.

Base (bed) for homemade drilling machine can be made of solid wood, chipboard or furniture ShieldBut it's better to use a channel, a metal plate or brand. To ensure the stability of the design and getting well the result, the bed must be masped to make it possible to compensate for vibration from drilling. Size for wooden satina 600x600x30 mm, metallic - 500x500x15 mm. On the basis of the machine must be attended by fastening holes, whatever it could be fixed on the workbench.

Rack for drilling machine can be made from a bar, round or square steel pipe. You can also use the old framework of the photo ending, an old school microscope or another device of such a configuration having a large mass and high strength.

Drill is attached using clamps or brackets. It is better to use the bracket with the central hole, this is allowed to achieve more good results when drilling.

Device of the drill mechanism on the machine.

With this mechanism drill can move vertically along the rack, it can be:

• Spring;
• Hinged;
• Similar to a screw jack.

Depending on the selected mechanism, you will need to make a rack.

In the photo, diagrams and drawings show the main types of designs of homemade drilling machines on which the drill is used.

Step-by-step instructions for the manufacture of steel rack.

The steering rack from the car is a sufficiently massive device, so the bed must be massive and attached to the workbench. All connections on such a machine are performed using welding.

The base thickness must be about 5 mm, it can be welded from the channels. The runoff for which the steering rail is fixed should be higher at 7 - 8 cm. It is fastened through the handwrites.

Since such a homemade machine becomes massive, the control unit is better to endure separately from the drill.

The order of assembling such a homemade machine:

• Preparation of parts;
• Installing a rack on the bed;
• Assembly device of movement;
• Installing the device on the rack;
• Installing a drill.

All connections should be securely secured, preferably with welding. If guides are used, then you need to do so that there is no transverse backlash. For more convenience, such a machine can be equipped with visits for fixing the workpiece under drilling.

In stores you can find and ready for a rack drill. When buying it is worth paying attention to the size of its beds and weight. Often, inexpensive structures are suitable only for drilling fine plywood.

Homemade drilling machine based on an asynchronous engine.

Replace drill in a homemade machine can be an asynchronous engine, such as the old washing machine. The scheme of the manufacture of such a machine is complex, so it is better if a specialist will be done with the experience of turning and milling work, the assembly of electricity.

How to make a drilling machine for printed circuit boards with your own hands.

For the manufacture of a drilling machine for printing boards, a low-power device is required. As a lever, you can use the mechanism from the carver of photos, a soldering iron. The backlight of the drilling site can be done using lED flashlight. In general, this machine is rich in the flight of creative thoughts.

For all lovers, make a product with your own hands, will excellent assistant . Such an aggregate, in a garage or house, will allow you to make holes with accuracy and accuracy, make the milling in the wood, drill a broken bolts from the thread and so on. However, the purchase of a drilling machine can do quite expensive, and why spend extra money when you can easily make a drilling machine with your own hands.

Common Characteristics for Drilling Machine

Drawing of the checker

For manufacture, it will take at least expensive materials. Basically, it is a primary means that can be found in any garage. Of course, the material must meet the requirements of the device.

For example, for the manufacture of a large stationary machine, without a metal frame, it is not necessary, and in the case of a desktop unit, only wooden materials can be used.

For all types of designs, three fundamental factor will be required:

• convenient drill feed lever;
• accuracy of drilling mechanism;
• reliable bed.

Undoubtedly, the feed lever should be placed under working hand Masters, left or right. However, this is not the only condition for convenience. Drill feed lever, should not be long, so as not to interfere with the work, but also not short, so that the pressure on the part is easier. For a better concept of the length of the lever, it is worth considering the drawings of the factory drilling machines. There the length is adjusted by the desired size.

Although the mechanism for drilling will be used, it should be fixed with the smallest error ratio. For this, the drilling mechanism is best fixed on the vertical bar. However, it is possible to use a solid wood panel with guide stalls.

Without reliable bed, the self-made drilling machine will not only work badly, but also will be dangerous to use. The base of the tool must be two times wider than the volume of the structure. This width will allow the design to be stable during the necessary pressure. In this case, the feed lever should not appear for the edges of the bed. Stationary machines, this rule does not apply, because they are fixed to the table surface or make with an individual table.

Drilling machine do it yourself

Which engine to use

Make a self-made drilling machine, using several variants of driving force:

• from a drill or screwdriver;
• from the electric motor;
• from hand drill.

At the same time, for each type of structures, the characteristics of stationary, portable or desktop. In the case of an electric motor, you can make a stationary or desktop unit, and in the case of an electric door, it will be either a desktop or a portable unit. Manual drill, can carry the character of a portable, not requireing the power of the device.

Drill as a tool for machine

To make a good drilling machine from a drill with your own hands, the design for this tool is better to do the tablet. It is worth avoiding the fixing the machine on the table. Electronic drill, a fairly popular tool, so it will be useful if it can be removed from the machine. In this case, the design on the table will be superfluous.

The desktop additive will require such materials:

• 45x30 cm bed, with a vertical bar fixed on it;
• fastening for a drill, a well-clutching tool body;
• metal slider moving by rod;
• wheel playing the role of the lever;
• steel cable, to control the movement by the lever.

For bed, it is better to use metal box With a wall thickness of 3 mm. To the box, welds a rack from square pipe. This rack will serve a barbell or tripod. Further, a tight slider should be attached to the tripod, which will hold the drill holder and the drill itself.

It will be difficult to choose exactly the appropriate slider, so it should be made of metal plates. Free space between the slider and the tripod should be no more than 0.5 mm, despite the fact that the tripod will be perfectly even.

Further sequence of actions:

• the slider is made in a height of 10-12 cm;
• to it, the holder is welded for a drill from the front and ears for fastening the wheel on the back side;
• in the ears, the rod, to which the control wheel is welded, and is fixed with a pin or welded nut;
• on the wheel rod, the steel cable (at least 6 turns) is cooled tightly, and both ends of the cable are securely attached to the top of the tripod and on the bottom. Thus, for the movement of the slider by a tripod, an effort will be required, and there is no own weight (together with the drill) so that the slider falls.

Electric motor construct

Similar machines, perfectly show themselves as stationary tools. To, figure out how to make a drilling machine from the electric motor, you have to consider the drawings and in the sphere of electricians.

For the machine, a two-phase engine will be required, which will significantly simplify the connection and expand the scope of the unit. Connects such an engine to phase and zero wires. Incorrect connection will affect only the direction of rotation. If, rotation will be in reverse side, the wires are changing in places, and the problem is solved.

Manufacturing stationary design For drilling, you will need:

• powerful engine frame that will easily move along the vertical line;
• countertop, where the strict vertical line pin will be fixed;
• in the role of the pin, you can take from the car. It will serve as a ready-moving engine tool moving;
• adjust the wheel to move and welcome the engine holder to the rail.

The principle of operation, such a machine is very simple. The motor drives the head for the drill, due to the belt transmission. At the same time, the engine and the cartridge for drill, during operation are inseparable and move along the vertical line at the same time, due to the joint mount.

Portable manual drill mechanism

Very convenient, use the drilling machine from the hand drill in cases where there is no way to connect electric drill To the power source. For the manufacture of the machine, you can use a wooden frame:

• the base is performed from the 30x20 cm boards and a thickness of 40 mm;
• the vertical plate is attached strictly at an angle of 90 o C;
• the vertical wall should also be made of thick boards, at least 30 mm, and metal corners and screws and screws will help securely securely.

On the vertical wall metal strings are attached (they can be taken with old furniture Or buy in the store), the holder of the hand drill is attached to them. Thus, the drill will be freely walking down and up, however, this is not enough. To the drill does not fall under its weight, the drill holder and the base of the machine is attached to the spring of the desired elasticity.

Do not forget about the handle that you will need to turn. Its movement should not interfere. As a result, an aggregate should be turned out, which is driven by manually and does not require nutrition.

Video: Drilling machine from drill do it yourself

The drilling machine is a unique device that is necessary for a domestic workshop. It allows you to not seek help in specialized workshops, but simply take and perform work on the groove yourself.

Due to this, a person saves a huge amount of money on the services of specialists in the turning case.

Make such a device can be made of girlfriend. Nothing difficult in the process is observed.

To produce a home drilling machine, you will need only an electric drill or steering rack.

Buying industrial aggregates will be in a penny, therefore it is advisable to make your model using drawings with sizes that are fully on the Internet.

Before you begin to create an aggregate, planning should be executed. This is a responsible step that requires a careful approach and drawing. You need to carefully measure and display the dimensions of the future machine on paper. If this is not done, in the work it will definitely go something wrong.

It's easy to be mistaken, and the availability of the drawing will not allow you to allow shortness. People who neglect this stage in creating a drilling machine with their own hands overpay in the process of its manufacture. What you need to take into account during operation:

Drawings with dimensions.

• Length, width and height of the equipment;
• The thickness of the aggregates;
• Technical characteristics of electrical equipment;
• Engine data that will serve as a drive for your machine;
• Power consumption power;
• Grounding;
• The number of consumables.

The drawing will allow you not just visually understand how to collect equipment, as well as how it will look exactly. The project will make it possible to more clearly determine the amount of production costs.

To assemble such equipment in your workshop, you do not need to have specialized objects or electrical engineering. All that will be required - 4 main components. First of all, under the additive machine should be selected. It will serve as a powerful base for the future device for a groove.

After that, we are determined with the rotation mechanism. It is better to choose an electric drill for him.

Tip: Take not too old, but not too new drill. The main thing is that it be in working condition, otherwise the equipment can quickly fail.

The third stage will choose a device for filing revolutions

on the working part of the drill, as well as to determine the rack, vertical type. The drill itself has a small mass, so it is not necessary to look for heavy-duty materials for the rack. Suitable ordinary board or chipboard.

Tip: The drive is ideal for asynchronous engine From the old washing machine.

The face of the same way is selected from those materials that will be stronger. She must keep everything on himself, as well as amortizing the rattling of the drill itself. To vibrations do not affect the equipment and accuracy of work, it is best to select strong metals. Very good, the old stand from the photo ventilator is suitable as the holder. True, you will need to create a boring machine with your own hands, you will need to finalize it.

Important! The accuracy of the opening drilled hole will depend on the quality of the connection between the rack and the bed of the unit.

Also, the creator of the home machine will need to use several steel strips to cut two guide strips. They will help carry out the movement of the pad on which the drill is located. To secure them, you can use screws. We take and screw everything to the rack.

Clamps will help increase the strength of fixing the drill. It is best to use steel, they withstand a higher load. To further absorb vibrations, between the block of the machine and the drill is best to put the rubber gasket. It will help you eliminate the process of rattling home equipment while working.

To better understand, browse the video below.

The basis of the flow of the movement of the machine is lever. It allows you to safely move the block with an electrical drill in a vertical position. There will be a spring, which will allow maintaining the drilling device in the desired tension.

Choose and install the steering rack for the drilling machine

So that your home equipment worked as convenient as possible, it is best to apply the upgraded steering rack during its creation.

If you are going to buy it new from the manufacturer, prepare a round sum,

because it is not at all cheap. More favorable solution - It is to choose a used part, best from VAZ 2108.

Tip: As soon as we bought such a spare part, you should carefully examine it, carry out prevention and repairs if required. Thus, it turns out to give her a smoother course while working with a drilling machine.

Now let's start making beds for your future drilling equipment

1. To make the housing you need to use a drill with a column. All of this should be installed on the table, which will serve as a platform for the future drilling machine. The size of the table should be around 20x30 cm.
2. Special design that will hold your electric drill is installed on the steering part of the unit. To tighten the bolts are used.
3. To build the rack itself, you should first select a P-shaped profile of steel with dimensions of 30x60x30. Then you need to fight it to metal leaf With a thickness of 2 mm. In theory, the rack itself is obliged to be height by 6-7 cm. Length of the speaker itself.
4. As the rod turn, the machine operator when creating equipment is best to apply the steering rack of the VAZ 2108, which was previously said.
5. In order to further increase the rigidity of the entire structure during installation, additional edges should be installed.

In order for the operator, there were no problems with the launch or disabling equipment during operation, you should consider the practical starting system and stop the engine of the drilling machine.

Not a very large machine can be useful in everyday life, and drilling equipment for working with micro circuit boards, as in the photo.

To make it, the creator will be needed:

• Micromotor or an engine running with high revs.
• Special collet for clips of small drills.
• Several wooden bars.
• Metal profile P-shaped.
• A lock ring that will help reliably perform the engine fixation.
• Mobile platform for a machine, which is created by their own hands from all sorts of materials found in everyday life.

Important! For the machine to ultimately disappointed you and worked clearly and accurately, you should pay special attention to lowering the drill. It should be carried out perpendicular to the board.

In the event that the motor has twisted for some circumstances, the user risks withdraw the drill failure. During the production of home drilling equipment, it is necessary to closely monitor the quality of the engine fixation. If it was installed unreliable, when the engine is running at high speeds, it will simply break out of the bed. It is fraught with a certainty of your property and harm to health.

How to make a coordinate table

IN home machine For drilling, the role of the coordinate table will be carried out by the feed mechanism. And at the same table, but for milling equipment there are somewhat different design. Therefore, it should be considered attentive.

This equipment is a special manipulator, which consists of the number of axes you need. It is needed to move in several directions and planes specialized technological heads of drilling equipment.

Important! To perform the milling table at home, do not do without the use of several modules linear type. They must be made of aluminum profile.

For moving movement when creating milling table You should use a special gear rail, as well as the reinforced belt. Instead, a ball-screw element will completely come down.

To set the coordinate table management to the creator, you will need to use CNC or controllers. Thanks to their installation, the user has the opportunity to manage the technical tasks assigned to the machine.

Important! When creating a milling table for a drilling machine, be sure to make the drawing before you start work. This will allow you to clearly understand the algorithm of actions and save yourself from unnecessary errors.

The calculation in this case is performed taking into account technical characteristics The drilling unit itself. The same design can be both lightweight and increased strength. And also there may be 2 or 3 coordinates. First of all, before creating a machine, you should understand the main role of it in your domestic workshop. And already repel from this in the process of design and further production.

When everything is ready, you need to make vice, otherwise you will not be able to fix the item at home, it is strictly forbidden to keep in your hands. The acquisition of old Soviet vice, made of steel or cast iron may be expensive. Chinese-made models, not everyone will come to taste, to the best of their shortglowness. Therefore, one of the economical options will make them independently.

You will need:

• Two cm thread screw and 15 cm long. In the fastener head, there must be a slot.
• Special ring with rings, which is used to twist.
• Studs.

It should be done a stationary sponge. How to make this element? To create, use the pine tree. It is available and strong enough. The board should be vaccinated to the tabletop.

To make a mobile part of the vice, you need a board with dimensions 2 cm thickness and 1.8 cm width. The length of the mobile sponges for the clips is obliged to be from 50 cm.

All that needs to be done is to cut holes with a diameter of 2.1 cm. In the studs, this diameter will be 1 cm. Then the creator simply inserts into the finished holes of the studs together with the screws, after which the nuts is hidden and tightens the bolts.

And on this, the production of domestic tombs is completed.

When you created your home drilling machine, you must need to check it.

Turn on the engine into the outlet and if you did everything right, you did not have a short circuit, there are no uncharacteristic sounds for the work of the unit - you can congratulate yourself with the successful completion of the project.

The homemade machine will allow you to carry out simple operations on drilling at home and save on auto repair shops or toiod.

Video how to make a boring machine

The only thing is that the equipment worked as long as possible, do not hesitate and do not be lazy once every six months view work surfaces along with the engine for damage or wear of parts. Timely identification of the problem will allow you to protect yourself from real trouble.

Home drilling machine (simply drilling) This equipment, the urgent need for anyone who at least something will once craft. Cleells sometimes make drillings with 2-speed transmission, tables for details having more than 3 degrees of freedom and even two-coordinate drilling-milling machines with CNC, see fig. below. But in this publication, we will consider the manufacture of a drilling machine with their own hands - such that is just drilling and milling - but for sure, clean, and confidently keeps its accuracy for a long time, subject to episodic short-term overload: stable processing accuracy is the main requirement for metal-cutting equipment. Which in amateur structures is performed, unfortunately, most often only due to a random coincidence.

Metal or tree?

Wood drilling "machine" -master

Beginners always seem to work on a tree easily and simple. A spoiled billet will be combined into small crafts or fuel. Perhaps, therefore, recently there is a real tune: homemade machines with responsible wooden details. As a result, monsters appear on the light, which probably would surprise Archimedes, see Fig. on right. However, remember: the best achieving accuracy on the tree +/- 0.5 mm. In metalworking cutting the greatest permissible error by default is 0.375 mm (in England and the US 0.397 mm \u003d 1/64 inches). On this, the question of using the tree as the main construction material of the machine is closed without discussion, which, they say, the tree is also deformed to the orders of the metal, wears and is damaged. Well, and lovers of deep internal self-satisfaction in products are free will for their money and work.

Drilling device

Fantasy The indispensable condition for any creative success, but in mechanical engineering it is useless without accurate calculations and reconciliation with verified solutions. The history of machine-tooling includes millennia - inhibitory turning and drilling machines with foot drive Used already at the end of the Stone Age. On the subject of this article, a proven sample is a desktop vertical-drilling machine of an industrial design. According to him, we will check, choosing and deciding how it is better to make a drilling machine personally: in operation there are single specimens of floriders, which passed for 100, and they still hold accuracy.

The desktop vertical drilling machine is shown in Fig.:

Its main modules of the bed, column, console and table for the part. Composite parts of the main nodes are slightly highlighted in color, and their components with flowers are grinding. The simplest table (not counting a wooden chumbach) - vice. Turning table allows you to also produce some milling operations. The bed is usually tightly attached to the workbench or other reliable support.

Screw clamp - Console Console Console Mini Machine

In operation, the console using a lifting switching mechanism, the slider is installed in the desired position, according to the size and configuration of the processed part, and fix. The spindle supply to the workforce is carried out by a separate feed mechanism. In amateur and industrial for home use, the lifting-turning mechanism is most often the operator's hand, and the lock is the screw clamp, see fig. on right; On TB and more is permissible. But what should be sure to be in the design of the drilling machine according to the requirements of the same PB, so this is a jackhammer or just a bunch: if you throw the handle of the feed, the spindle or carriage with it should automatically bounce upwards. In home drills, the chipper most often the spring installed in a suitable place, see below.

Note: industrial production, Sale and use in enterprises and in workshops IP drilling machines without a jack-free device is prohibited by PTB.

Do or buy?

The electric drill is already ready-made drive, transfer, spindle and cartridge in the monoblock. Put it on the machine carriage - and you can drill. According to the accuracy, the decision, generally speaking, is not optimal (see below), but in many cases acceptable, but delivering from the need to order expensive accurate parts of increased accuracy, see below. In view of which the beds for the installation of a drill are now sold except that not on the street with trays; Prices are available. Choosing such to make a drilling machine from a drill, follow primarily by the mode of operation of the equipment; It depends on it:

• Episodic drilling / milling for oneself with accuracy, it turns out - the bed is plastic cast or steel stamped. Mechanism feed lever with crankshaft (see below). Bearings of carriage sliding (see below) Steel steel or with kapron liners. Prices - $ 20- $ 30.
• Regular drilling for yourself or to order with conventional engineering accuracy. Processed materials - to the hardness and viscosity of ordinary structural steel. All the same, but the sliding bearings steel according to steel (worse) or with bronze bushings, and the bed is cast iron cast or (more expensive) also composite vibrating absorbing. Prices - $ 30- $ 40.
• Regular drilling and milling of any tool tool materials with periodic tool overloads and / or with increased accuracy - gliding bearings only with steel bronze, steel iron. The mechanism of feeding the gears (even see below); Console vibrating absorbing. Prices - $ 60- $ 180.

Note: As a rule, a swivel-sliding table for a part is optional to the beds for a drill, allowing individual types of milling. Price within $ 20.

Choose a bird

Fear for a drill (which sellers for some reason are persistently referred to as racks). It is necessary to choose not by the manufacturer ("China" - not "China"); Now in the market and "German China" is fully, not to mention the products of post-Soviet states. You need to check the design.

The first - samples with plastic not caprony liners of sliding bearings are definitely rejected: the beating and rails of drill more than 0.5 mm will appear on the 10th - 20th "hole" and will further increase. The second is the backlash console. We take it for the far end, we shake up and down and on the sides when clamped the lock. A noticeable "chatter" should not be (the tactile sense of a non-monitored person feels 0.4-0.5 mm beating).

Next - inspection of the structure, see Fig. below. For ordinary drilling, it is suitable for poses. one. Perfect option - on pos. 2: Tsanging clamp drill, offset of the Wide column reduces the vibration of the console by an order of magnitude, and turning its bass to 45 degrees, you can mill from your hand with an accuracy "How can you know" the part on the regular non-sliding table, removing a pair of table fixtures, because At the same time, its displacement manually relative to the horizontal working axis of the console will be linear.

But the sample on the pos. 3 Do not take anyway. First, the column of his column is low and its fastening is unreliable. Secondly, longitudinal grooves The table facilitates the manual milling "how it will turn out", but, unlike the diagonal, do not quenitate the vibrations of the bed. Moreover, they will concentrate, where they are shown by the arrows (a tide under the column is taken too narrow) and from there straight to the column and the table.

What is cheaper?

Suppose the price of your favorite window does not suit you. Or drill if "breaking", with a shock mechanism, former building structures And the patron beating is visible to the eye. Then the first thing we find out if the wizard owning a turning machine of increased accuracy (not rude 0.02 mm). What, by the way, is not a fact - the machine of increased accuracy is very expensive and never pays off on the stream of community orders. But, we set, found. Take the drawing in fig. On the right, we go to him and ask whether it will be able to sharpen it from steel no worse than 30xgs, and how much will take care. "This" is the drawings of the spindle of the desktop drilling. The rest of its parts can be turned on conventional machine, Or find in collapse at the iron bazaar or in my cheek. Most likely, it turns out that buying a bed + table is cheaper, and if you estimate the expenses for the rest, then it may be drawn up and the drill of increased accuracy. There are such on sale; They can be found in the absence of a shock mechanism and a collar specifically for installation in the bed: an accurate steel cuff is hoping on it.

If you still do

Nevertheless, there are cases where the self-made drilling machine will be cheaper or at all for nothing, or the most best drill On the bed it will not replace it. The fact is that the column from the working body (tools - drills, cutters) is also transmitted to the column other than bending and vibratory loads. Due to this difference shoulder lever from the axis of the column to the neighbor to it and the distant edges of the tool; Cutlery loads from the cutter, ricking the material alone with an order of magnitude more than from the drill. Therefore, to obtain the accuracy of processing the drill on the bed over 0.1 mm is unreal (why - see below), but for example, under the thread M3 you need a hole 2.7; Under m2.5 - 2.2, and the processing error in this case turns out to be unacceptable. In general, to make a drilling with your own hands makes sense, despite the costs if:

1. You are a radio amateur and work with components with a pitch of 2.5 and 1.25 mm ("" thousands "with a step of 0.625 mm are mounted only on the plane). Then you need a drilling machine for printed circuit board With accuracy not worse than 0.05 mm;
2. You are engaged in other subtle wood and metal work. Eg, make a beautiful elegant box or reliable Tyach. In the house, applying only manual drilling, it is impossible;
3. Drilling / milling you from the case for the case for yourself and the accuracy will suit you what will be released, and in the honeycombs a lot of metallochlama.

Note: In the latter case, you were lucky, suddenly the old children's bicycle came out somewhere. Pipes of his frame from excellent steel, and the wheel sleeve is almost ready-made spindle; Only an adapter with a Morse cone under the instrumental cartridge remains to order. Working thoughtfully and gently, from the old bicycle you can make a drilling machine with an accuracy approach. 0.1 mm, or in fact a gift box for a drill, see for example. video:

But, let's say we need accuracy higher, and it is necessary to mill the grooves, without losing it. In this case, the layout diagram of the machine acquires paramount importance.

The optimal option is the location of the spindle and drive on different sides of the column, pos. 1 in fig. The heavy motor in this scheme acts as counterbalance of seismous buildings: reflects in antiphase vibration and spindle loads from the spindle. In the column area, each other is partially quenched. Quenching as much as possible if the center of gravity of the carriage is accurately along the axis of the console, and the higher the thinner drill and less pressure on it. Those., The accuracy of the machine on fine work increases, and at the same time it withstands rather significant overloads without her loss.

Note 4: Making a drill to accurately work with a direct drive to the spindle and the location of it and the drive on one side of the carriage, if there is a ready-made vibration base, for example. from the old microscope (under 2), etc. optical devices.

In mini machines for printed circuit boards and jewelry work, an unpleasant effect is observed: to obtain accuracy above 0.05 mm, the column has to do disproportionately thick, pos. 3. It is caused by the fact that its ability to absorb vibrations and twist loads is determined by the cross-sectional area, which decreases the part in the square. For boards under the components with a pitch of 3.5 mm conclusions, as well as fine fitter-joinery operations of a rather accuracy of 0.05 m. At the same time, bending stripping column have the basic effect on its deterioration. To parry them, it is enough to apply a dual column of a rod 10-14 mm from ordinary structural steel, pos. 4. If enough ordinary accuracy is 0.375 mm, then by driving a column, the drilling machine for episodic works can be done even from a drill and water supply propylene pipes, pos. 5. Its resource to the loss of accuracy is small, but also the material is cheap and processing to order does not require.

Innings

An important role for the accuracy of the drilling is also the device of the spindle mechanism (carriages in the drill machine): jerks and / or uneven feed force at least increase the drill bit. When drilling a thin carbide drill, in this case, its development, breakage and as a result is an irreparable damage to the workpiece.

In the machines and the beds for the drill of the increased accuracy, the transmissive feed mechanism is used (on the left in Fig.), Providing its complete uniformity and, which is especially important for manual feed, a precisely proportional to the resistance of the instrument's instrument. For this, a toothed rack and a gear-tribe with a well-defined teeth profile are evolvent. Otherwise, the feed will go jerks even with absolutely smooth jamming on the handle. Make a "knee" a couple of rack-gear with the same evolvent teeth unrealistic; It is not possible to choose a suitable ready-made pair. Therefore, the transmotable-cutting mechanisms of feeding in homemade drills are extremely rare.

More often make a simple single-dimensional feeding mechanism, in the center in fig., But this is not optimistic. At the beginning and at the end of the workstop, when the smoothness of the feed and the accuracy of the drillings is especially important, it is not enough in hand, and in the middle of the course it is redundant, which is growing like a chance of jamming of the instrument in a viscous material. From these shortcomings, the mechanism of feeding with a crankshaft lever, on the right; In addition, it additionally extinguishes the vibration of the console. The shoulder ratio of knees take approx. 1: 1.

Table with feed

The drilling of fine fragile / viscous parts is obtained more accurate, and the probability of care and breakage of the drill is less, if the spindle is fixed fixed, and the table with the part is supplied up to it, therefore, in many drillingings for thin work, the table is supplied with a separate feed mechanism. According to the inertia of thinking, it is also often made tooth-roll, see for example. Further. But, given that the mass of the table in this case is much more than that part, the table with the lever feed turns out to be at all worse, but is fully accessible to manufacture at home. Its device is shown in Fig.:

The nuance is one: so that the clip does not lead to the assembly, it is tightly inserted into the through hole of the base and weld from below (from the exhaust). You need to boil the Ohma-2 electrode or thinner with a constant current of 55-60 and short diametrically opposite grabs ("tytches"). Dimensions of the table for printed circuit boards and jewelry work 60-150 mm in diameter; Thickness 6-12 mm. The diameter of the table shank is 12-20 mm; Length by the size of the feed + (20-30) mm. The tube under the shank (wall thickness from 1.5 mm) It is desirable to dilute or fly and pass the sweep so that the shank walks in it smoothly without noticeable backlash. The short arm of the lever makes a length of approx. equal to the diameter of the table; Long - what you want.

Console

Let's see once again in Fig. with factory fabrics. The designs of their consoles with semi-frame carriages are similar; They are quite rational, but designed for automated and robotic production: precise casting and then finishing on the place on the CNC unit and the laser measurement.

The diagram of an analogue of the console with semi-grade of amateur development is given to the left in Fig.:

The first thing that draws attention is to be cut 5 parts from a thick steel sheet, stitched (processed forest cutter) On the evenness and parallelism of the parties. The second, end sections of inserts, shaped dark gray, should also be smooth, clean, parallel. Those. And here without milling machine not enough. Finally, out production conditions Run the sliding pairing of the slider and guide carriage (shown by the arrow) with a backlash of less than 0.1 mm unreal. I estimate the ratio of the arm of the lever - the crossbill of the drill is obtained more than 0.5 mm.

The design of the console of the drilling machine, a little technological in mass production, but adapted for the manufacture by handicrafts, is shown on the right in Fig. (The feed mechanism and drive with the bracket are not conditionally shown). Moreover, in it, the drill bit on the heterogeneity of the material causes the carriage chains on the column and the guide to the opposite sides, and the side care of the tool does not exceed the size of the back in the sliding liners. Only one item is cut out of the thick plate - the slider 4. The exact processing is only needed in the column clamping area and the installation of the guide, and 3 bronze liner bushings will definitely welcome at the place of any medium qualification turning, if you give it a column and guide carriage (they can be Cool with normal accuracy).

So that the entire assembly node on welding has not behaved, cooking needs as before. Case: Ohma-2 electrode or thinner, the constant current of up to 60 A. The seams boil also alternately by grabs: "Bag" on one, the same on the same far located symmetrical. Then grabs the neighbor to the first seam, the same on the diametrically opposite to him, etc., etc., until all the seams are wrapped.

Note: The accuracy of the machine with the described console will be higher if it is not collected on the welding, but on the screws with the sizing high-strength glue for metal (cold welding). First, everyone is collected without glue, unwinding the closure on parallelism and tighten the fasteners. Then the screws alternately turn out, the glue is dripped in from the socket and toughe it tight. Mouored business, but to produce a homemade floring with a drill bit less than 0.02 mm actually. If, of course, the spindle and the cartridge are not fettered worse.

Errors in design

All efforts to make a boring machine with their own hands will go to the pump, if with its design, fundamental errors were made. The most common of them are shown in Fig.:

Typical errors in the manufacture of drilling machine

Pos. 1 is this console or how? For a long time of the tool, this frame will not stand for a long time. About accuracy and talk no. Pos. 2, in addition: to make a column of a burglar drill machine cannot be. The bending loads pipe keeps, but against the twisted powerless, and the vibrations only enhances.

Pos. 3 - Make a florid from the old seducing photographer is great, especially since it has been completed at least with the initial but optical accuracy. But! The magnifier rod holder is not designed to focus on the tool. As a result, when drilling an organity, the care of the drill on the supply of 20 mm reaches 1.5 mm (!). A bracket is silhouusin: This material does not absorb vibration, quickly gets tired, and the bracket breaks less than the 200th hole even when driving printed circuit boards.

Pos. 4 - Dowing the column in the transverse direction does not give anything. The stability of the machine to loads will be no higher than on a single pin of the same diameter. Pos. 5, in addition: an intimitive spring, asymmetrical relative to the axis of the column, does not quit vibration and twist loads, but enhances them. Since then, it was necessary to put 2 identical springs on both racks. It would be better to make a column, as shown here:

Video: Drilling machine from drill do it yourself

Pos. 6 - installation of the drive and spindle on one side of the column, and even asymmetric, does not reduce, and increases vibration, because They are transmitted to the column in the phase, see above. Pos. 7 - Where is the chipper? Yes, it can not be here, once the drive of the helix feed. The screw can accurately set the slider (which is not here at all), which is not necessary on the home machine in general, but in no case serve a carriage! This construction is slightly populated by fragments of drills and chips, and the eyes of the operator in close proximity to the danger zone.

Collapse of structures

Samples are successful technical solutions, as well as not such essential constructive flaws, consider the examples of several homemade drilling machines.

For a radio amateur, model store, a miniaturian and / or jeweler, an interest can represent a simple mini-drilling machine with a direct drive (drawings are given in Fig. Right). The feature of the design - the drive motor is rigidly attached to the slider, and the feed is only from the bottom. The vibration damper and the absorber of the twist load is the massive electric motor itself, exactly as an anti-seismic cargo on high-rise buildings. Due to this, all the details, in addition to the Morse cone with the adapter on the motor shaft, can be made of conventional accuracy: the accuracy of drilling is determined by the beats of the motor shaft + the beating of the cone with the adapter + the beating of the drill itself. The table with the transmission mechanism changes without problems changing to the lever. The engine is better to use the collector direct current: In asynchronous motors with condenser starts due to the unevenness of the rotating magnetic field and slip the rotor in it, the rotation of the shaft is less uniform. In addition, the speed of rotation of the collector motor is well adjustable at least a simple rheostat, and to adjust the speed of the asynchronous engine, you need to change the feed current frequency. The same - for synchronous with a magnetic rotor. The maximum rotation frequency of the motor shaft is 800-1500 rpm. Power on the shaft for drilling holes up to 3 mm - 20-30 W; For holes up to 6 mm - 60-80 W.

Note: For milling, this machine is not suitable, because Motor shaft bearings are not designed for lateral loads and the machine in this mode will quickly lose accuracy.

Here in fig. There are drawings of the already full-featured drilling mini-machine of the same purpose also with direct drive:

It is equipped with a separate spindle, which allows, first, refueling the maximum diameter of 6 mm in the cartridge; For 8-10 mm drills, the engine is weak. Secondly, make the milling of dental boras. Apparently, the author of the structure often applies this particular operation, based on which the motor rotation speed is selected. Without decreasing it, drill on this machine is needed by carbide drills, and for the use of ordinary supplement the design of revolutions; In this case, the motor is needed at least 60 W. Stagging the lack of this machine is a simple feed lever drive - easy to remove: the feed lever is replaced with the crankshaft without the improvement of the rest of the parts. To increase the processing accuracy, it is also desirable to put the second jack-free spring (pos. 14 in Fig. And 9 in the specification; there is still integrated) symmetrically the first, on the other end of the leash of the spindle. A more serious lack of design - the jackhafts do not participate in the quenching of vibrations and the vibrations. At the speed of rotation of more than 5000 rpm, their effect on accuracy practically does not affect, but already at 1500 rpm, the drill bit on the working move increases approx. twice.

Drawings of a drill mini-machine, conceived as full-fledged, but with annoying errors, are given in rice; The design of the carriage is similar to the console in the pre. Designs.

Thanks to the installation of a strong jackhaft in the appropriate place here it turned out to be a hard to firm the spindle in the carriage, which at first glance reduced the number of parts requiring increased accuracy of manufacture. But only when the table is submitted from the bottom, and then the fixation of the slider 5 and the carriage 4 pairs of screws 17 and 16 acc. Unreliable and spoils the column; It would be better to apply screw clamps. And when feeding the liberated carriage, the lever only its articulation prevents the carriage. The backlash of any of the hinges of the lever is 0.02 mm, taking into account its ratio with the knee's shoulder length, will give lateral care of the drill on 2 mm and more, parry that is possible only with hand. In this machine, it would be more appropriate to the console with an additional guide carriage described above; In this case, it would be possible to achieve the tool beating due to the backlash in the interfaces of the machine itself no more than 0.02-0.03 mm.

On this rice. - drawings of the beds for a drilling machine from a drill with a semi-grade carriage, "almost like this".

It is all good, and something is even better than the "firm": plates 5, preventing the side displacement of the carriage, perfectly "catching" and suppress the tool vibrations in their most nudy. The question arises only one thing: how to do it all if in the garage (shed) not having to sleep in anticipation of the master's hand Machina, worthy of a small machine-building plant? It is easier to make a drilling machine from a drill as shown in the video:

Video: Homemade Stand Machine for Drills

The old Soviet joke is integrity:

"His dear comrade Leonid Ilyich his visit to some industrial enterprise. Going along the workshop, suddenly the Secretary of the hand stops the retinue, is suitable for one to the worker in the machine:

- Comrade Tokar ...

- Yes Petrovich I ...

- Okay. Comrade Tokar Petrovich, tell me frankly - do you drink vodka?

- And however, like! We use!

- And if the bottle costs 10 rubles, will you drink anyway?

- Will.

- A 25?

- Will.

- And 50?

- Will.

- A 100?

- I'll still be.

- Petrovich, ..., so where can I take so much money for salary?!

- Gee ... what happened here ... This phytulka (shows) how half a liter cost, it will cost. "

To whom the joy, who alas, but those Petrovich, the Secons and production relations are no more. And it will not - completely ineffective turned out to be.

About steering drillings

A fairly popular request on this topic is also "Drilling machine from the steering rack a passenger car" It seems to be the finished transducer of the rotational motion into linear, and even with the geoidal gear ratio: to slightly "peck" the drill, "catching microns" do not need a hand. You only need to adapt to the rail to the rake, make a drill holder (see fig. Right), and ready, see video.

The drill is a multifunctional tool, but in human hands on weight from her difficult to obtain a special accuracy of drilling. Drilling machine from drill with their own hands on the proposed drawings may be by the way. If the drill is a tool of everyday demand, it can be fixed on the bracket by clamps. When the energy tool is turned on into a permanent composition, the start-up node of the machine can be reached.

When the drilling machine is necessary

Drilling machine from a drill is used by those who create homemade items. Make them with fantasy, find them needed details The store is difficult and lost meaning. Masters love to create everything alone. Often, in front of this craftsman, the question of the accuracy of the holes, which he must drill. Everyone knows that it does not happen on the kneel and on the knee. It will take a holder, to fix the tool with a snap.

What kind of drill to use depends on the nature of the wobbly. The manufacture of electronic circuit boards for radio amateurs requires a cross-section. Twisted from 0.3 mm, manually at the slightest deviation from direct corner Drill burst. Only a small drilling machine will save position, but it costs expensive. Output one - do it yourself.

On its own, created from the primary materials, the machine can be:

• perform through and deaf holes;
• drill in a thin blank with a centered perpendicular hole;
• cut a hole or cut the thread.

Main pieces of drilling machine

The drilling machine, which means that the drill is assumed to collect with or quickwise. The tool must be attached to reliable vertical stand and have freedom of movement up-down. The rack should be vertically installed and fixed on a massive plate from the bottom, which is called the bed. The tool is easy to describe, but to achieve accuracy of operations, you need to create a well-verified design. In special publications and the Internet, you can find the drawings of the drilling machine from a drill with their own hands from various materials.

Any tool created by the standards in the enterprise is equipped with security elements - protective screens, locks from accidental inclusion. By creating your instrument, you must take care of protection, take action so that the machine does not get into the hands of children.

Drilling is accompanied by severe vibration. Small concussions destroy the structure of materials, the exact execution of operations will not be achieved. The vibration of soft gaskets are quenched, which are mounted in the places of tool fastening and a massive bed - vibratory waves are stupid. Promotes the shallow tremors of the tool. Bad assembly, centers, displacement of the center of gravity. All moving parts of the self-made drilling machine from a drill are adjusted sweaty, with minimal gaps.

Build a boring machine according to the drawings

To help the master, the first time building a drilling machine from drove with their own hands is offered drawings. Collect the design of wooden bars and the use of furniture plates under the face will be able to any person who owns primary carpentry skills. Fastening the design of wood is performed by self-drawing.

For fastening elements use corners. The drill mount node can be collapsing, on removable clamps, or to build a tool tight. An important part of the device will be a moving salad device, along which the drill is moving during operation. Often to create polozov use furniture telescopic guides. Simple and understandablely represented how to assemble a boring machine from your own hands, on video:

The proposed option is universal, it is equally well coping with metal, wood and other materials. But he is cumbersome and for small operations, the craftsmen make miniature machines using a tripod from a photo fellow and a welded bed. In some cases, the steering stand from the car goes. Metallic frame structures require plumbing skills. How to make a boring machine is solved, depending on the presence of primary parts and appointments.

An example is perfect unusual design A small device for radiomasters will serve as a machine from an old school microscope and a wiper engine of the UAZ car. The engine gives a large torque, but for its use it will be necessary to lengthen the shaft. Its power and torque is sufficient to drill thin as a foil sheets of metal. The bracket itself needs refinement - the exact setting is removed, the microscopic node and the miniature engine is mounted.

Minds of work on a boring machine

The newly manufactured machine requires additional adjustment. Trial inclusion is carried out on the table, where everything is removed, not related to the case, objects. The machine is considered correctly assembled and ready for further work if:

• the drill rotates along the axis, without creating the expanding sectors by rapid rotation;
• lowered down the drill must accurately enter into the recess or the outlined point on the bed;
• adjust the movement of a drill on Salazkov tight, but without hot jerks;
• for through holes, a special substrate was cooked so as not to spoil the bed.

During drilling, remember the heating of the device, raise periodically snap-in with deep drilling, can be used for cooling.

Always remember the speedless cutting tool He is a source of increased danger. You can only spend the reference on de-energized equipment. Eyes should always be protected by glasses.

A selection of various drilling machines created by the hands of craftsmen, for all cases of life confirms the inexhaustible mixture of folk craftsmen. You can buy everything in the store, but you can create your own tool - a wizard worthy.
