CNC machine with their own hands drawings. CNC milling machine in home (garage) conditions. Remove future spare parts

The machine from the printer is easy. To do this, it is enough to have equipment that is not sorry to disassemble on parts. The CNC machine can be made with a stepping type electric motor. With it, you can carry out milling or engraving of various wood blanks, plastics, some metals. Homemade aggregates from the printer (CNC) can provide high processing speeds - up to 2 mm per second.

What will serve as the basis?

Making a homemade CNC machine from the printer is possible from the equipment of the matrix type. You can use any, which is available, regardless of the brand of the manufacturer. Also for high-quality management and efficient operation of aggregates from the printer, other parts are needed - engine, carriages, gear belts, guides, various gears.

Necessary materials and tools

For the manufacture of CNC machines, they will need such materials:

plywood (used for the device body, therefore should have a thickness of at least 15 mm);
aluminum corners that have 20 mm shelves;
self-tapping screws to connect the main elements of the aggregate;
bearings 608 (3 pcs.);
m8 bolts with a length of 2.5 cm (several);
stud M8;
rubber hose;
m8 nuts (2 pcs.);
dremel;
linear type bearings (4 pcs.);
bracket 80;
glue.

The milling machine will not work, if not to prepare some tools - pliers, screwdriver, vice, hacksaw, file, sideboard. If you manage to find an electric door, work will also greatly ease.

Manufacturing technology

From plywood, it is necessary to cut the walls of the housing - the side 37x37 cm, the rear 34x37 cm, 9x34 front. The fixation of these items should be made using self-tapping screws, having done small holes by electric drill.
On the Y axis, you can use corners as guides. They are attached to the side walls at a distance of 3 cm from the bottom. For a more accurate installation in the right place, 2 mm spool is made. The corners themselves (recommended length 34 cm) are screwed using self-tapping screws.
The working surface should be formed from the corners of a length of 14 cm. One bearing is fixed below, and from above two. During the execution of this operation, it is necessary to comply with high accuracy, which will ensure the correct movement of the countertop.
At a distance of 5 cm from the bottom on the Y axis, the hole for the engine is drilled with a diameter of 2.2 cm. Also on the front wall of the case should be done holes with a size of 7 mm. It is necessary to set the stroke screw support bearing.
Screw the stroke can be made independently from the construction stiletto.
A rubber hose coupling is installed. It quenches the vibration from the screw of the progress and increases the service life of the motor bearings. For the manufacture of the coupling, pick a hose having the same diameter as the axis of the motor. From one end it is put on the pulley of the drive and glue. On the other hand, the hose is attached to the stroke screw.
The nut is done with a screw hole with a diameter of 2.5 mm and M3 thread. After that, it is twisted on the axis.
On the axes, the guides from the printer are installed.
Finished carriages are installed on the axis.
To obtain the Z axis, the base of the plywood is 6 mm thick, which is made using PVA glue. Subsequently, bearings are installed on it using epoxy resin. Also make a hoding nut using the former scheme. Guides - from the printer.
Instead of the spindle in a homemade machine, a dense will be set with a bracket holder. This node is fixed to the Z axis using self-samples.
The supports for the carriage z axis are also made from plywood (base 15x9 cm, bottom and top 9x5 cm). On the top board make a hole under the bearing, and on the bottom - under the guides.
After assembling all elements of the z axis, they are mounted on the housing.

Step-by-step instructions for creating a CNC machine with their own hands easily and quickly, without extra costs.

CNC machine from printer with your own hands

You will also need conventional tools, such as drill, drills, screwdriver and others.

Step 1st: Find the old printer or scanner

To make a homemade CNC machine from the printer, first needed to be stockpit. This stage is the most pleasant in the process of assembling the machine, since it is attempts to find that trash from which people seek to get rid of. You can use your materials or buy them. But if you reducing the machine costs as much as possible, the best option will be the CNC from the old printer. Here are the items that you need to find:

Tablet scanner
Old printer

After executing the procedure described above, promote pieces of plastic, suitable on the rod (2 pcs. On each rod), to the desired places, and align them, then place the sheets on top. Then turn the design and glue them.

Repeat the procedure for each axis.

For Yasi Y.

Now, it's time to drill holes required to fix billets when processing on a planned CNC from the printer.

Step 5th: Installation of the electric motor

Depending on how the electric motor you took, you will need various fasteners to install it, since they all differ from each other.

It is advisable to use stepper electric motors from printers due to the ease of their installation, but the electric motors from the scanners will also work well.

In the course of the third step, you had to drill holes to install the electric motor, and now you can only consolidate it.

The choice of a suitable type of connecting coupling, with which the stepper motor is connected to the threaded rod, depends on the type of engine existing at your disposal.

In this case, an elongated nut was used as a connector, but you can make it from plastic - the main thing is that it has sufficient dimensions.

All you need to do is drill a hole in the center of the rod from the engine side, corresponding to the diameter of the stepping motor shaft, then drill the hole with a diameter of 8 mm under the threaded rod on the other side.

After that, cut the thread from the side, on which the hole is with a diameter of 8 mm, and glue parts of each other.

Step 6: Making Threads

After you installed the nut, it's time to fix the threaded rod and glue the nut to one of the rectangular plates with dimensions of 38x44x12 mm.

It is necessary to make sure that the center of the nut with the threaded compound coincides with the center of the threaded rod.

After performing this procedure, you must turn out the node similar to the one is shown below.

Necessary materials:

Repeat the procedure described above for each axis.

Step 7th: It's time to glue

Now you have to be prepared all three axes, so it's time to align them and glue.

A piece of white plexiglass with dimensions of 508x304x6 mm was used as a piece of 508x304x6 mm, which can be purchased in the store of goods from plastic.

You can use a piece of smaller size, but it is undesirable.

As soon as you have a base and homemade CNC, the machine from the printer already begins to circumvent its features, stick the axis "X" to it, and then glue the axis "y" to the plastic base of the top of the x axis. You must have a node similar to the one is shown below.

To perform this procedure, use acrylic glue.

By the way, it is also suitable for gluing foamed PVC.

After that, glue the axis "z" to a piece of plexiglass with dimensions of 203x101x6 mm.

Necessary materials:

Step 8: And where is the z axis?

Do not worry - they also did not forget about it. Go ahead.

Now we need to make an attachment for a multifunctional tool on a sheet of plexiglas located on the "Z" axis.

To do this, use a clip for fastening pipes and the clamp - you can purchase them in any construction store at a very low price.

It is necessary to make a small ledge to fix the multifunctional tool on the plexiglass sheet, since the clip is deformed when you insert a multifunctional tool into it.

Place the clamp of the plexigla sheet at the top of the protrusion and stick it.

Necessary materials:

Step 9th: Paradise Sting

Now that the mounting for a multifunction tool on the axis "z" is installed, it's time to install the plexiglas and a sheet that connects them together.

To do this, it is necessary to make a square hole in the center of the sheet from the plexiglass with dimensions of 10 "x16" x5 / 16 "to turn through it the axis" z ".

After that, the thick piece of the plexiglass should be installed for the support of the axis "Z".

Now glue the axis "z to a piece of plexiglass" and make sure that the latter performs above the upper edge of at least 1/16 "to ensure the presence of a flat face.

Necessary materials:

Step 10th: What high racks!

Now it is time to glue the racks with dimensions 1 1/2 "x16" x1 "to the top of the axis" z "from the plexiglas, then glue them to the lower base.

Necessary materials:

Step 11th: We already finished?!

The answer to this question will be "no", but in relation to the mechanical part of the design is so. You also need to work on an electronic part of the machine, and how to do it - learn in the second part of the article, which will be published soon.

Such work takes quite a long time, although at first glance it may seem quite the opposite, so by the time you complete the execution of all the procedures described above, the instruction for the manufacture of the screen will be ready.

All the necessary plastic can be found in the garbage container with plastic, and the rest has purchased in the building of building materials and a local specialized store of metal products.

At first, the CNC machine from the printer can work on a stepping electric motor from the printer, and it will be good to cope with its tasks, but will be better if you decide to get a more powerful engine.

Ready! You made a CNC from the printer with your own hands, almost (or completely) for free.

In this review, I will tell you from which details and components a given printer was collected. I will show how the main nodes are arranged. And also make the starting machine on Arduino. Turn on the spindle.

The idle software for starting the machine with such a connection scheme see. This example is very simple, but it has a fairly large number of flaws.

For the assembly of the CNC, the machine from the parts from the printer was used:

3 Matrix Printer A3 format.
Furniture guides: 2 pairs of 500 mm. And one pair by 300 mm.
Board 25x100, 25x25 bar, 8 mm thick plywood.

Milling on a self-made CNC milling machine.

Knowing that the CNC milling machine is considered to be more complicated technical and electronic equipment, many masters think that it is simply impossible to make it yourself.

However, this opinion is not true: you can make such a device with your own hands, but for this it is necessary to have not only its complete drawing, but also a set of certain tools and suitable components.

CNC Machine with your own hands (drawings)

Deciding on the creation of a self-made special CNC machine, remember that it can leave a lot of time. In addition, you will need a lot of money.

To make a milling machine that is equipped with the CNC system, you can use 2 ways: to purchase a ready-made set of specially selected parts, from which such equipment is assembled, or find all components and independently assemble a device fully suitable for all your requirements.

Preparation for work

If you planned to make a CNC machine yourself without using a finished set, the first thing you need to do is to stay on special schemeon which such a mini-device will work.

Assembling equipment

The base of the collected milling equipment can be a rectangular beam, which must be firmly fixed on the guides.

The supporting design of the equipment should have a big rigidity. When it is installed, it is better not to use welded connections, and attach all parts only with screws.

In milling equipment, which you will collect yourself, a mechanism must be provided, which will ensure the movement of the working device in the vertical direction. It is best to take a screw transmission for it, the rotation to which will be transmitted using a toothed belt.

Main part of the machine

An important part of such a machine is its vertical axis, which can be made from an aluminum plate for a homemade instrument. Remember to the dimensions of such an axis were accurately chosen under the dimensions of the device being created..

The article describes a homemade machine with CNC. The main advantage of this variant of the machine is a simple method for connecting stepper motors to a computer via the LPT port.

Mechanical part

The bed of the window of our machine is made of plastic thickness of 11-12mm. The material is not critical, you can use aluminum, organic glass Phaneur and any other available material. The main parts of the frame are attached with the help of screws, if you wish, you can additionally place the places of attachment with glue if you use wood, then you can use PVA glue.

Caliper and guides are used as a guide steel rods with a diameter of 12mm, length 200mm (on the axis z 90mm), two pieces on the axis. The calipers are made of textolite with dimensions of 25x100x45. Textolol has three through holes, two of them for guides and one for the nut. Guide parts are fixed with screws M6. Caliper x and y In the upper part have 4 threaded holes for mounting the table and the Z axis node.

Caliper Z guide axis z are attached to the caliper x through a steel plate, which is transitional, the dimensions of the plate 45x100x4.

Stepper motors are installed on fasteners that can be made of sheet steel with a thickness of 2-3mm. The screw must be connected to the axis of the stepper motor using a flexible shaft, which can be used as a rubber hose. When using a hard shaft, the system will not work for sure. The nut is made from brass, which is glued into the caliper.

Assembly Assembling homemade CNC machine, carried out in the following sequence:

First you need to install all guide components in the caliper and fasten them to the sidewalls that are first not installed on the base.
Caliper Move on the guides until they achieve a smooth stroke.
Tighten the bolts, fixing the guide parts.
To base, the caliper, the guide and sidewall node, use the screws for the attachment.
We collect the Z node and together with the transition plate attach it to the caliper of X.
Next, set the running screws together with couplings.
We establish stepper motors connecting the engine rotor and screw with a clutch. We draw strict attention to that the driving screws rotate smoothly.

Recommendations for the assembly of the machine: the nuts can also be made of cast iron, you should not use other materials, the screws can be bought at any construction store and trim under your needs. When using screws with M6x1 thread, the nut length will be 10 mm.

Go to the second part of the CNC assembly of the machine with your own hands, namely to the electronics.

Electronics

The power supply as a power supply unit was used to 12 volt 3A. The unit is designed to power stepper motors. Another voltage source for 5 volt and with a current of 0.3a was used to pick up the controller chip. The power supply depends on the power of stepper motors.

We give the calculation of the power supply. The calculation is simple - 3x2x1 \u003d 6a, where 3 is the amount of stepper motors used, 2 is the number of subtitled windings, 1 - current in amperes.

The controller controller controller was assembled in total on the 3rd 555TM7 series chips. The controller does not require firmware and has a fairly simple principal scheme, thanks to this, this CNC machine can make a person who is not particularly versed in electronics.

For the experiment, a stepper motor from an old 5.25-inches was used. In the 7 bit scheme is not used because Applied 3 engines. You can hang the key to turn on the main engine (mill or drill).

The driver for stepper motors to control the stepping motor is used by the driver, which is an amplifier with the 4th channels. The design is implemented in total on 4 transistors of the KT917 type.

You can also use serial chips, for example - ULN 2004 (9 keys) with a current of 0.5-0.6a.

For control, the VRI-CNC program is used. A detailed description and instructions for using the program is on the official website.

By collecting this CNC machine with your own hands, you will become the owner of the machine capable of performing mechanical processing (drilling, milling) plastics. Engraving in steel. Also, a CNC homemade machine can be used as a graph-beader, you can draw and drill printed circuit boards.

CNC do it yourself drawings

Knowing that the CNC milling machine is a complex technical and electronic device, many craftsmen think that it is simply impossible to make it with their own hands. However, such an opinion is erroneous: it is possible to make such equipment yourself, but for this you need to have not only its detailed drawing, but also a set of necessary tools and related components.

Processing of dural billet on a homemade desktop milling machine

Deciding on the manufacture of a self-made milling machine with CNC, keep in mind that it can escape a significant amount of time. In addition, certain financial costs will be required. However, without afraid of such difficulties and correctly approaching all the questions, it is possible to become the owner of an affordable, efficient and productive equipment available, which makes it possible to carry out the processing of blanks from various materials with a high degree of accuracy.

To make a milling machine, equipped with the CNC system, you can use two options: buy a ready-made set, from specially selected elements of which such equipment is assembled, or to find all components and with your own hands to assemble a device that fully satisfies all your requirements.

Instructions for assembling self-made milling machine with CNC

Below in the photo you can see the CNC milling machine with your own hands, to which a detailed manufacturing and assembly instruction is attached with the indication of the materials and components used, accurate "patterns" of the machine parts and approximate costs. The only negative is the instruction in English, but it is possible to understand detailed drawings, and without knowing the language.

Preparatory work

If you decide that you will design a CNC machine with your own hands without using the finished set, the first thing you need to do is to stop your choice on the schematic diagram on which such mini equipment will work.

CNC milling machine circuit

As the basis of milling equipment with CNC, you can take an old drilling machine in which the working head with a drill is replaced by the milling. The most difficult thing to be designed in such equipment is a mechanism that provides the movement of the instrument in three independent planes. This mechanism can be collected on the basis of carriages from the non-working printer, it will ensure the movement of the tool in two planes.

To the device assembled on such a schematic diagram, easy to connect software control. However, its main disadvantage is that only billets made of plastic, wood and fine sheet metal can be processed on such a CNC machine. It is explained by the fact that carriages from the old printer, which will ensure the movement of the cutting tool, do not have a sufficient degree of rigidity.

Lightweight version of the CNC milling machine to work with soft materials

In order for your homemade CNC homemade machine to perform full-fledged milling operations with blanks from various materials, a sufficiently powerful stepper motor must be answered for moving the working tool. It is absolutely not necessary to look for the engine that is precisely a step type, it can be made from a conventional electric motor, subjected to the last small refinement.

The use of a stepper motor in your milling machine will make it possible to avoid using the screw transmission, and the functionality and characteristics of homemade equipment will not be worse. If you still decide to use the carriage from the printer for your mini-machine, it is desirable to choose them from a more large-sized model of the printed device. To transfer efforts on the milling equipment shaft, it is better not to apply usable, and gear straps that will not slip on the pulleys.

Node belt transmission

One of the most important nodes of any similar machine is the mechanism of the mill. It is its manufacture that it is necessary to pay special attention. To properly make such a mechanism, you will need detailed drawings that need to be strictly followed.

CNC milling machine drawings

Drawing number 1 (side view)

Drawing number 2 (rear view)

Drawing number 3 (top view)

Establish the equipment assembly

The basis of the self-made milling equipment with CNC can be a rectangular beam, which must be securely fixed on the guides.

The carrier design of the machine should have high rigidity, when it is installed, it is better not to use welded connections, and you only need to connect all the elements using screws.

Machine frame fastening node by means of a bolted connection

This requirement is explained by the fact that the welds are very poorly tolerated vibration loads, which will necessarily be subject to the supporting design of the equipment. Such loads will eventually lead to the fact that the machine frame will begin to collapse over time, and it will occur in geometric sizes, which will affect the accuracy of the equipment setting and its performance.

Welded seams When mounting the frame of the homemade milling machine often provoke the development of the backlash in its nodes, as well as the deflection of the guides formed during serious loads.

Installation of vertical racks

In the milling machine, which you will collect with your own hands, a mechanism must be provided that ensures the movement of the working tool in the vertical direction. It is best to use a screw transmission for this, the rotation to which will be transmitted using a toothed belt.

An important part of the milling machine is its vertical axis, which can be made of aluminum plates for a homemade device. It is very important that the dimensions of this axis are exactly adjacent to the dimensions of the device being collected. If you have a muffle furnace, you can make the vertical axis of the machine with your own hands, sings it from aluminum in size specified in the finished drawing.

Upper carriage node placed on transverse guides

After all components of your homemade milling machine are prepared, you can begin to assemble. This process begins with the installation of two stepper electric motors, which are attached to the equipment body behind its vertical axis. One of these electric motors will be responsible for moving the milling head in a horizontal plane, and the second is for moving the head, respectively, in vertical. After that, the remaining nodes and units of homemade equipment are mounted.

Final stage of assembling machine

Rotation to all nodes of self-made equipment with CNC should be transmitted only by belt gears. Before connecting a software control system to the assembled machine, it is necessary to check its performance in manual mode and immediately eliminate all the identified disadvantages in its operation.

You can see the process of assembling the milling machine with your own hands on the video that is easy to find on the Internet.

Stepper engines

In the design of any milling machine equipped with CNC, stepper motors are necessarily present, which ensure the movement of the tool in three planes: 3D. When designing a homemade machine for this purpose, you can use the electromotors installed in the matrix printer. Most of the old models of matrix printing devices were equipped with electric motors with a sufficiently high power. In addition to stepper electric motors from the old printer, it is worth taking durable steel rods that can also be used in the design of your homemade machine.

Fastening a stepper motor on the top carriage

In order to make the CNC milling machine with your own hands, you will need three stepping motors. Since there are only two of them in the matrix printer, you will need to find and disassemble another old printing device.

It turns out a big plus if the engines you found will have five control wires: this will significantly increase the functionality of your future mini-machine. It is also important to find out the following parameters of the stepper electric motors you find: how much degrees are carried out in one step, which is the supply voltage, as well as the value of the winding resistance.

To connect each step motor, you will need a separate controller.

The design of the self-made milling machine with CNC is collected from nuts and studs, the dimensions of which should be pre-pick up the drawing of your equipment. To fix the shaft of the electric motor and to connect it to the heel, it is convenient to use a thick rubber winding from an electrical cable. Such elements of your CNC machine, like fixators, can be made in the form of a nylon sleeve in which the screw is inserted. In order to make such simple structural elements, you will need a normal file and drill.

Electronic equipment filling

Manage your CNC Machine made with your own hands, will be software, and it must be properly pick up. Choosing such a provision (it can be written independently), it is important to pay attention to that it is workable and allowed the machine to implement all its functionality. This software must contain drivers for controllers that will be installed on your milling mini machine.

In the CNC homemade machine, the LPT port is mandatory, through which the electronic control system and connects to the machine. It is very important that such a connection is carried out through the steady electric motors.

Choosing electronic components for your machine made with your own hands, it is important to pay attention to their quality, since it is from this that the accuracy of technological operations will depend on it, which will be performed on it. After installing and connecting all electronic components, the CNC system needs to download the necessary software and drivers. Only then follows the trial launch of the machine, checking the correctness of its work under the control of downloaded programs, identifying deficiencies and their operational elimination.

All the above-described actions and listed components are suitable for manufacturing with their own hands of the milling machine not only the coordinate-boring group, but also a number of other types. On such equipment, you can perform the processing of parts with a complex configuration, since the working organ of the machine can move in three planes: 3D.

Your desire for your own hands to collect such a machine controlled by the CNC system must be supported by the presence of certain skills and detailed drawings. It is also very desirable to see a number of thematic learning videos, some of which are presented in this article.

CNC machine with your own hands / DIY / collective blog

Today, the CNC machine has a wide range of applications. Among the main operations performed on it, it is possible to note the manufacture of furniture, stone processing, repair, construction work, etc.

CNC machine made in industrial conditions - the pleasure is quite expensive. But it turns out to be complex at first glance, the mechanism is very simple and available in manufacturing in domestic conditions with their own hands.

For first experience, it is best to stop your choice on the machine with a moving portal. This is due to the fact that simplicity and functionality are combined in it.

For the manufacture of the main parts of the machine Take the MDF plate. This material is small dispersed fractions that are pronounced under greater pressure and a temperature in one stove. The main characteristics of the MDF include high density. Therefore, they are perfectly suitable for the manufacture of CNC machines with their own hands. On the equipment from the MDF, plastic processing can be carried out, wood, making engraving, but do not turn out metal parts with high accuracy. This is connected with the low resistance of this material to the loads.

To begin with the drawing of our machine print on the printer. Then the resulting patterns can be pasted on MDF. So much easier and more convenient to cut the details of the future machine.

Accessories that will be used in assembly can be purchased in any construction or construction store.

In addition to accessories, the following tools will be required for the manufacture of the machine: drill, screwdriver and hacksaw. If you have an electrolybiz, then it is better to use it. This will greatly simplify the process of drinking parts.

Start the manufacture of the machine. For this printer, the drawings are printed on the printer, we stick onto the MDF plate using the adhesive pencil for paper. Choosing it in the store, stop your choice in the thick. This will significantly speed up the process of sticking patterns.

Now you can directly drink blanks. In this model, all parts have practically straight lines and the most simple contours.

After all templates are cut, proceed to drump out holes. It should be paid to the fact that many of them have a large diameter. Therefore, that the surface of these holes is neat and smooth, it is better to use crowns or pumps for grinding. Thus, you will have the opportunity to carefully clean the holes to the desired diameter.

Now you can start assembling the CNC machine according to your drawings.

Since we plan to use the machine at home, it is necessary to establish a fencing. This will avoid the flushing of dust and dirt from the workpieces.

For these purposes, it is possible to use foam, fiberglass, thin paneur, etc. Do not forget to make a small hole in the fence.

Through it can be connected with an exhaust from the old vacuum cleaner. This will ensure maximum dust capturing and chips. The reverse effect of using such a "dirt leader" is a strong noise.

The next important stage of the assembly of the CNC machine is the electronics. After all, it is important, because With it, the control process takes place.

In this case, you can use two ways to solve. The first of them is to collect the necessary controller scheme by independently by purchasing all the necessary details.

The second way is easier to buy a ready-made controller in the store or on a radio station. Which of the proposed ways to choose is to solve you. If you are not very versed in radio engineering and decide to buy a finished item, then it is recommended to stop the choice on TV6560.

The choice of this element is the possibility of selecting the necessary nutrition, depending on the stepping motor used, the presence of protection against overload and overheating, the use of a plurality of software, etc.

In case the controller you will be made independently, the old scanner or MFP is perfectly suitable. The ULN2003 chip is selected from it, steel rods and stepper motor. In addition, you need a DV-25 connector with a wire, a socket for powering the controller itself. If you want to have computer control of your machine, then there will be a computer to which you connect the obtained equipment.

To create a controller, we take any fee available we have. On it neatly the soldering iron solder the ULN2003 chip. At the same time, do not forget about polarity.

The diagram shows that there are two power tires. Therefore, the conclusion of the chip with a negative sign we solder to one, but with a positive one. After that, by the output 1 ULN2003, we attach the output of 2 parallel port connector. To the conclusion 2 ULN2003, we join the output of the 3 connector. Accordingly, the conclusion of the scheme ULN2003 4 we connect with 5 connotor terminal, etc. But the output of zero with 25 with the output of the parallel port we solder to the negative tire.

The next step is to solder the stepper motor to the control device. It is possible to make it correctly only by the method of trial and errors, because Most often, there is no documentation for the conclusion of the existing electric motor. Therefore, it is recommended that the engine wires are equipped with crocodiles clamps. Thus, the process will go faster and easier.

The next our step is the connection of the wires with the conclusions 13,14,15,16 microcircuits ULN2003. Now we will solder wires to the nutrition bus with a plus sign. At the end, install the power socket.

Our controller is almost ready. Now we set it on steel rods and fix in prepared nests. In order for the operation of the wires during operation, it is better to fix them with a thermoclaus.

Drawing of homemade cnc machine

You can download the drawing of the homemade CNC the machine by reference at the end of the article.

In the archive offered to download, there is a CNC drawing machine for assembling with their own hands.

This is a fairly common type of CNC machine with a moving portal.

This drawing is very different in that it is not only given detail - when each machine part is drawn separately and has an affixed size, but also the assembly drawings of each of the nodes are presented.

CNC Machine according to such a drawing can be made from almost any material. It may be duralumin plates and multilayer plywood. You can use durable plastic or plexiglass in the design of the homemade CNC machine.

The drawings have a vector DXF format and can be smeared into any sizes.

In the simplest case, you can take engines from the Matrix Printers of the EPSON FX1000 type A3 format, from the same printer to take the steel guides along with the slide node.

As a running screw in the budget version of the homemade CNC, the machine is used with a M6 or M8 threaded. The running nuts are better to order a turner and pull them out of bronze. The bronze nut can "walk" for 5-7 years with the daily use of the CNC machine for 8-10 hours.

The running screws are the consumable material, and the running nuts can be served not yet on one homemade machine.

However, I did not read about how the driving nuts made from plastic or Ghetinaks were used.

A homemade CNC made from undergraded means will allow you to process wood, plastics and non-ferrous metals.

For the processing of metals and steel such a machine becomes affordable due to the weak stiffness of the structure.

However, it can be used for engraving or as a boring machine with CNC control on metals.

But how frees - unlikely. When milling metals, shock loads occur - for example, during milling one groove, another groove met and then the mechanical blow occurs, which is transmitted to the design of the machine and the chassis screw.

For homework, such as milling of sets for the assembly of aircraft model from Balza - such a machine easies easily justifies the cost of its manufacture!
