CNC machines from aluminum profile Drawings Description. Step-by-step instructions for assembling the CNC machine with their own hands. Features of the construction profile

PureLogic R & D offers to purchase a structural aluminum profile on favorable conditions. This is a durable and easy material to create engineering systems Any complexity and destination. The machine profile is used for the manufacture of CNC machine stannes. In addition, it is used to build employee jobs, travel axes, coordinate tables, etc.

The structural aluminum profile is manufactured using hot extrusion technology. It is obtained by extruding the material through a special extruder matrix. Various aluminum alloys can be used as the feedstock.

The most important advantage and main difference of the machine from the machine profile is the possibility of rapid change in the design, its extension, rebuilding and modernization.

This section presents:

design aluminum profile;
set aluminum desktops of various sections;
aluminum corners;
cable Channels.

The guide profile can be complemented by various components:

vibrooporas;
end and groove plugs;
wheeled supports;
end mounting plates.

Features of the construction profile

Products made of high-strength aluminum alloys and having a complex cross section provide:

the possibility of prompt assembly and disassembling structures. This allows you to quickly conduct repair work, Various modernization activities, as well as move the equipment to a new place. It is possible to make changes to the object being created at any stage of its readiness, which is especially important in the manufacture of devices of special substance and various non-relocated machines;
high strength of compounds in the absence of welding;
optimal combination of low weight and strength characteristics. This is achieved due to the deformable alloys based on aluminum and complex cross-sectional configuration;
minimum labor and financial costs, efficiency of execution when designing and creating structures of any complexity.

To the question of how to make a CNC machine, you can answer briefly. Knowing that homemade milling Machine With CNC, in general, - a difficult device having a complex structure, designer is preferably:

acquire drawings;
purchase reliable components and fasteners;
prepare a good tool;
have a turning and drilling machines with CNC to quickly make.

It will not hurt to watch a video - a kind of instruction learning - where to start. And I will start with the preparation, I will buy everything you need, I will deal with the drawing - here correct solution novice designer. therefore preparatory stagepreceding the assembly is very important.

Work preparatory stages

To do homemade CNC For milling, there are two options:

Take the finished chassis set of details (specially selected nodes), from which we collect equipment yourself.
Find (make) all components and start assembling CNC machine with your own hands, which would have answered all the requirements.

It is important to determine the purpose, dimensions and design (how to do without a picture of the CNC homemade machine), find the schemes for its manufacture, acquire or make some details that are needed for this, get the move screws.

If it is decided to create a CNC machine with your own hands and do without ready-made sets of nodes and mechanisms, fasteners, you need the scheme assembled on which the machine will work.

Usually, found principal scheme Devices, first simulate all parts of the machine, prepare technical drawings, and then on them on turning and milling machines (sometimes it is necessary to use both drilling) manufacturers of plywood or aluminum. Most often, work surfaces (called another desk) - plywood with a thickness of 18 mm.

Assembling some important machine knots

In the machine that you started collecting personally, it is necessary to provide a number of responsible nodes that ensure the vertical movement of the working tool. In this list:

screw transmission - rotation is transmitted using a toothed belt. It is good because they do not slip on the pulleys, evenly transferring efforts on the shaft of milling equipment;
if a stepper motor (shd) is used for a mini-machine, it is desirable to take a carriage from a more overall model of the printer - more powerful; Old matrix printing devices had enough powerful electric motors;

for a three-way device, you will need three shd. Well, if each there is 5 control wires, the mini-machine functionality will increase. It is worth estimating the value of the parameters: supply voltage, winding resistance and angle of turning shd per step. To connect each SD, a separate controller is needed;
with the help of screws, the rotational movement from the shd is converted into linear. For achievement high precisionMany consider it necessary to have ball-screw pairs (SVP), but this is not cheap component. Picking for the installation of blocks a set of nuts and fastening screws, choose them with plastic inserts, this reduces friction and eliminates the backlash;

instead of a stepping type engine, you can take a conventional electric motor, after a small refinement;
the vertical axis, which provides the movement of the tool in 3D, encompassing the entire coordinate table. It is made of aluminum stove. It is important that the axis sizes are adjacent to the dimensions of the device. In the presence of muffle furnaceThe axis can be filled in size drawings.

Below is the drawing made in three projections: side view, rear, and from above.

Maximum attention - bed

The required stiffness machine is ensured by the bed. It is installed onto a movable portal, a system of rail guides, shd, work surface, z axis and spindle.

For example, one of the creators of the CNC homemade machine, the carrier of the frame made aluminum profile Maytec is two parts (cross section 40x80 mm) and two end plates with a thickness of 10 mm from the same material by connecting the elements by aluminum corners. The design is amplified, a frame of smaller profiles is made inside the frame in the form of a square.

The bed is mounted without using welded connections (welds are poorly removed to carry the vibration loads). It is better to use T-shaped nuts as an attachment. On the end plates it is provided for installing the bearing block for installation. running screw. You need a sliding bearing and spindle bearing.

The main task made by its own hand the machine with CNC CNC was determined by the manufacture of aluminum parts. Since he was approached by the workpiece with a maximum thickness of 60 mm, he made the clearance of a portal 125 mm (this is the distance from the top transverse beam before working surface).

This uneasy installation process

Collect homemade CNC machines, after preparing components, better strictly according to the drawings so that they work. The assembly process, applying the running screws, should be performed in such a sequence:

the knowledgeable sample begins with fastening on the body of the first two shd - behind the vertical axis of the equipment. One is responsible for the horizontal movement of the milling head (rail guides), and the second for moving in the vertical plane;
the movable portal moving along the X axis carries the milling spindle and the caliper (z axis). The higher the portal will be, the greater the workpiece can be processed. But the high portal, in the processing process, reduces the resistance to emerging loads;

for the attachment of the Z axis, the linear guides use the front, rear, upper, middle and lower plates. There, make a lodgment of the milling spindle;
the drive is collected from carefully selected nuts and studs. To fix the motor shaft and attach to the heel, use the rubber winding of the thick electric circular. As a retainer, there may be screws inserted into a nylon sleeve.

Then the assembly of the rest of the nodes and aggregates of the homemade begins.

Intim the electronic stuffing machine

To make your own CNC hands the machine and manage it, it is necessary to operate correctly selected numerical control, high-quality circuit boards and electronic components (especially if they are Chinese), which will allow on the CNC machine to implement all the functionality, processing a piece of complex configuration.

In order for no problems in management, self-made CNC machines, among the nodes, are required:

stepper enginesSome stopped for example NEMA;
the LPT port through which the CNC control unit can be connected to the machine;
drivers for controllers, they are installed on the milling mini machine, connecting in accordance with the scheme;

switching fees (controllers);
36V power supply unit with a downstream transformer converting to 5V to power the control circuit;
laptop or PC;
the button responsible for an emergency stop.

Only after that the CNC machines are tested (at the same time, the sample will make its trial start, downloading all programs), the existing disadvantages are detected and eliminated.

Instead of imprisonment

As you can see, make a CNC that will not give way to Chinese models - real. Having made a set of spare parts with necessary sizehaving high-quality bearings and fastener enough for assembly, this task is under power to those interested in software technology. The example does not seem to search for a long time.

In the photo below - some samples of machine tools that have numerical management, which are made by the same craftsmen, not professionals. No item was done hastily, arbitrary size, and suitable to the block with great accuracy, with careful excretion of the axes, using high-quality head screws and with reliable bearings. True statement: As you collect, you will work.

The CNC is the processing of dural billet. Such a machine that gathered the craftsman, you can perform many milling works.

And so, as part of this article, the instructions, I want, what would you, together with the author of the project, 21 years old mechanic and designer, made their own. The narrative will be carried away from the first person, but know that to greatly unfortunately, I share not with my experience, but only freely retell the author of this project.

This article will have enough drawings, notes to them are made on english languageBut I am sure that this tech will understand everything without unnecessary words. For the convenience of perception, I will deal with the narrative on the "steps".

Preface from the author

Already at 12, I dreamed of building a car that will be able to create various things. The car, which will give me the opportunity to make any item homemade. Two years later, I came across the phrase CNCor if we talk more precisely, then on the phrase "CNC milling machine". After I learned that there are people able to make such a machine on their own for their needs, in their own garageI realized that I could also do it too. I must do it! Within three months I tried to collect suitable details, but did not move from the spot. Therefore, my obsession gradually faded.

In August 2013, the idea to build a CNC milling machine again captured me. I just graduated from the undergraduate of the University of Industrial Design, so I was quite confident in my capabilities. Now I clearly understood the difference between me today's and five years ago. I learned to work with the metal, mastered the technique of work on the handwritten metalworking machines, but the most important thing I learned to apply tools for development. I hope that this instruction will inspire you to create your CNC machine!

Step 1: Design and CAD Model

It all starts with thoughtful design. I made a few sketches to better feel the size and shape of the future machine. After that, I created a CAD model using SolidWorks. After I simulated all the details and machine nodes, I prepared technical drawings. I used these drawings for the manufacture of parts on handwritten metalworking machines: and.

I admit honestly, I love good convenient tools. That is why I tried to make so that operations maintenance And the adjustment of the machine was carried out as simple as possible. Bearings I placed in special blocks in order to be able to fast replacement. Guides are available for service, so my car will always be clean at the end of work.

Step 2: Stanna

The bed provides the machine to the need hardness. A mobile portal will be installed on it, stepper motors, z axis and spindle, and later the work surface. To create a carrier frame, I used two aluminum profiles of Maytec with a cross section of 40x80 mm and two end plates from an aluminum thickness of 10 mm. All elements I connected to aluminum corners. To enhance the design inside the main frame, I made an extra square frame from the profiles of a smaller cross section.

In order to further avoid dust from entering guides, I installed aluminum protective corners. The corner is mounted using T-shaped nuts, which are installed in one of the grooves of the profile.

Bearing blocks are installed on both end plates to install the drive screw.

Step 3: Portal

The movable portal is the executive body of your machine, it moves along the X axis and carries the milling spindle and the Caliper of the Z axis. The higher the portal, the thicker the workpiece you can process. However, high portal is less resistant to loads that occur during processing. High side portal racks perform the role of levers relative to linear rolling bearings.

The main task I planned to solve on your CNC milling machine is processing aluminum details. Since the maximum thickness of the aluminum blanks of 60 mm suitable for me, I decided to make the portal's lumen (the distance from the working surface to the upper transverse beam) is 125 mm. In SolidWorks, I converted all my dimensions into a model and technical drawings. Due to the complexity of the details, I processed them on the industrial processing center with CNC, this additionally allowed me to process the chamfer, which would be very difficult to do on a hand milling machine for metal.

Step 4: Caliper axis Z

In the design of the Z axis, I used the front panel, which is attached to the bearing of movement along the Y axis, two plates for amplifying the node, the plate for fastening the stepper motor and the panel for installing the milling spindle. On the front panel, I installed two profile guides for which the spindle will be moved along the Z axis. Please note that the screw Z's screw does not have a counterface at the bottom.

Step 5: Guides

Guides ensure the possibility of moving in all directions, provide smoothness and accuracy of movements. Any backlash in one of the directions can cause inaccuracies in the processing of your products. I chose the most expensive option - profiled hardened steel rails. This will allow designs to withstand high loads and will provide me with the accuracy of positioning. To ensure the parallelism of the guides, I used a special indicator during their installation. The maximum deviation relative to each other was no more than 0.01 mm.

Step 6: Screws and Pulleys

Screws convert rotary motion from stepper motors to linear. When designing your machine, you can choose several options for this node: a pair of screw nut or ball-screw pair (SVP). The screw-nut is usually more exposed to friction for operation, as well as less accurate relative to the SVP. If you need increased accuracy, it is definitely necessary to stop your choice on the SVP. But you need to know that the ShvP is quite expensive.

Now just more about the main assembly.

So, the following components will be required to assemble the frame:

Cut profile 2020 (two longitudinal, 5 transverse, 2 vertical parts)
Profile corners 16 pcs
T-nuts m3 or m4 for groove-6mm
Screws for installation with T-nuts (m3 or m4, respectively, 8 ... 10 mm, plus M3x12 for fastening engines)
Strut (corner under 45 °)
Tool (screwdriver)

Once the conversation about the profile, then just in case, duplicate about the purchase and cutting of the profile at the gathering

This is structural.
I bought immediately sliced \u200b\u200bin the size of the profile set for 2418.
There are two options - profile without coating (cheaper) and coated (anodized). The difference in the cost is small, I recommend with a coating, especially if used as guides for rollers.

Choose need type Profile 2020, then enter "cut in size". Otherwise, you can buy one segment (whip) 4 meters. When calculating, keep in mind that the cost of one cut is different, depending on the profile. And that the cut is laid 4 mm.

Enter the sizes of segments. I made the machine 2418 a little more, these are seven segments of 260 mm and two vertical 300 mm. Vertical can be done smaller. If the machine is needed longer, then two longitudinal segments are more, for example, 350 mm, transverse also 260 mm (5 pcs).

I confirm (I must definitely add to the cutting card)

Checking the basket

The profile is obtained by 667r with the cutting service.

Delivery is carried out by TC, it is possible to calculate the cost by calculator, as the profile size is known to you, the weight is very well considered in the cutting map. For calculation, the option "Supplier's charges" is needed. Delivery business lines will cost cheaper, about 1000 rubles.

You can pick up by pickup in Moscow.

In one place office, warehouse and workshop, where they cut a profile in size. There is a showcase with samples, you can pick up a profile on the spot.

So, we start collecting the frame desktop 2418.
Here is a cut profile.

In this design, I increased the axis Z (a little more by a couple of cm than others) to use the machine as a CNC florider.
In the original axis Z is the shortest. These are already deciding under your goals. To lengthen the working field, you need to buy two profile segments (longitudinal steam) larger on the desired length (for example, + 10 cm), respectively, the guides are extended (+11 cm with a pair of 8 mm of shafts) and the screw (+10 cm screw T8). For money, it turns out completely cheaply voiced +10 cm: the cost of 10 + 10 cm profile about 40 rubles, guides and the screw will be connected in a plus $ 6 (check).

Here are the cooked corners

This way should be installed T-nuts in the slot. You can not be traded from the end, but to install directly into the profile groove sideways, but then control the rotation and installation of the nut, since it does not always happen, you need some skill.

Clean profile, burrs no

Profile-doubled, that is, from the 2020 series, with respectively twisted 20mm x 20 mm, grooves 6 mm.

So, first we collect a p clip of the frame, the two longitudinal parts of the profile and one extreme crossbar. Much from which side is not to collect, but consider that there is a central transverse crossbar, which is shifted closer to the rear. It is part of the vertical plane, and the displacement size depends on the departure of the z axis and the spindle. Placed in such a way that the axis of rotation of the spindle was in the center of the machine (Y axis).
Next, we collect the middle cross. It is more convenient to first install both corners on the profile segment and fix and then install to the frame.
Apply the profile segment, measure the same range of the line, tighten the screws. Screws need to be tightened leisurely, give the time T-nut to check and take their position in the groove. If it does not work first time, weaken the nut and repeat again.

We establish the last part of the horizontal frame. It is more convenient to be subject to a long screwdriver. Do not be lazy and control the straight corners of the resulting design by the coated and the diagonal - line.

Since the corners of the design are directed towards each other, it is not fundamentally in what order to collect. I did like in base design CNC2418. But intuition suggests that the distance between profiles makes sense to increase, especially with a greater height of the portal. Well, it can be done later.

Next, we start collecting the mount of the vertical portal

The assembled portal is installed on the horizontal part, secure with 6 corners (installed in the direction of three sides from the vertical profile).

We establish, we observe the campaignness of segments (by the coal). Then in turn dragged all the screws.

In the original to strengthen the vertical, a special extrusion corner is used under 45 °. I could not find a similar on sale, replaced 3D print. The link to the model is at the end of the topic.
Update.: It turned out in the original 3d printed too.
If you can replace it with perforated fasteners from shops or furniture corners. It will not affect quality.

The design turned out at first glance durable, not shaky. It can be seen that the engine plate is shorter than the bundle of KP08 + SK8 calipers. I will dismiss sewn.

In fact, this frame is a copy of such a CNC2418 machine design, except that I did not directly copy the dimensions, made a little more in order to smallest cutters from guide and screws.

The frame assembly is completed, now you can do the installation of the engines. I use 3D printed flanges to install engines. Top is advisable to make assembled with guide holders, bottom - without holders, as the Y axis should be wider. The Y axis is advisable to install SK8 and KP08 calipers, as in the original machine. The calipers themselves can be printed on the printer or buy (links at the end of the topic, and were also in the first post).

For one of the axes (X and Y axis, I have the same length) took the "target". I have not yet knew my "Wishlist" on the size of the machine. As a result, trimming from the screw will go to the z axis, you will only need to buy a brass T8 nut.

Packed was in cardboard packaging, every detail in the package separately

The kit looks like this: the engine with a short wire, the chassis screw T8, two calipers KP08 and two clutches 5x8.

There is a similar and, as well as without an engine on (with calipers and nut).
If you take without a big stock, then the option is 400 mm, it will go well for the "enlarged version" of the machine

Additional information - photo set separately

Engine marking RB STEP MOTOR 42SHDC3025-24B-500, LED location NEMA17

Included a short wire for connecting. Conveniently, you can simply increase the length, not touching the connectors.

Screw T8, Nut

Caliopers kr08.

It is convenient to mount on the profile. If a wide flange is used for installation - it is better to use the KFL08 caliper version, it allows you to mount the screw not to the profile, but on the flange.

The clutch 5x8 is a split clutch for connecting the engine shaft to the screw.

That's how the engine is attached in the original on the X axis on a small aluminum plate.

Made the same thing, only with the printed plate. At the same time will be a caliper for the guides.

The excess screw length has already cut off for the Z axis (z axis during the process, the information will be separately, most likely 3D printed).

With high probability, you will need to lengthen the wires of the engines in order to carefully lay it on the profile in the upper part to the electronics board (most likely there will be CNC SHIELD). Yes, and it would not hurt to establish the terminats of extremes.
The main information on the assembly is already available, you can proceed to estimate costs))))

Calculation
Now, according to requests in the comments in the first part, I propose to discuss cost-calculation. Naturally, I spent less than the specified, since the engines and most of the components were in stock. Strong cheaperit will be if you use homemade printed corners for profile, calipers, flanges and so on. To work the machine in drilling printed circuit board and in milling soft materials It is unlikely to affect. Yet a good option - The use of perforated plates from construction / hozmags. It will go to enhance the angles, including vertical and for installing the engine, provided that the central part is drilled under the shaft. You can use self-made aluminum sheet or plywood to the perforated fastener.
Definitely need to be purchased profile 2020.Otherwise it will be a machine of a completely different type. Can also be made of aluminum corner or rectangular pipeBut only from love for art))) There are more optimal constructions in terms of hardness for assembling from angle / pipe.
Unambiguously need a profile T-Naiki. You can buy T-bolts, but T-nuts are more universal (since the length of the screw can be applied any).
But the rest can be changed at its discretion, you can even instead of the running screw T8. use stud.from stainless steel. Is that the number of steps on MM to recalculate will be in the firmware.
Enginescan be removed from old devices / office equipment and plan planting Already under a specific type.
Electronicsalmost any (Anduino Uno / Anduino Nano, CNCSHIELD, MEGA R3 + RAMPS, A4988 / DRV8825 drivers, you can use the Mach3 adapter board and TB6600 drivers. But the choice of electronics limits the software used.
For drilling, you can use any enginedC, which allows you to install a collet cartridge and has decent revisions. In the baseline, there is a high-budged engine 775. For milling, it is possible to use watt spindles by 300 with Cangua ER11, but it greatly appreciates the machine as a whole.

Approximate cost calculation:
Profile 2020 (2.5 meters) \u003d 667r
Profile 2080 (0.5 meters) on the desktop \u003d 485 p
Two 300 mm 2x $ 25
. Lot on 20 pcs is $ 5.5 with delivery
Approximately 4r / piece if you take a big package. You need at least 50 pcs (mounting engines, calipers). I do not consider the screws to them, usually a few kopecks / thing depending on the quality. Total about 400 ... 500r.
Engines 3 pcs $ 8.25 each
Electronics $ 2.
$3.5
A4988 three pieces for $ 1

The machine comes out about $ 111. If you add spindle:
$9
$7.78,
that the total cost is about $ 128

3D printed parts do not appreciate. It is possible to replace with perforated plates / corners from the fasciner and similar stores. Wires, isolate, time spent also not evaluate.
Let me remind you that not in all options for the CNC2418 packages there are such good 775 engines and, moreover, Tsang ER11.

Options cheaper.

Complicated in the manufacture, except technical components, it has electronic device, Install which is only a specialist. Contrary to this opinion, the ability to assemble the CNC machine with their own hands, if you prepare the necessary drawings, schemes and components in advance.

Conducting preparatory work

When designing CNC, with your own hands at home, it is necessary to determine what scheme it will work.

Often, used as the basis of the future apparatus is taken.

Drilling machine can be used as a base for CNC machine

It will require replacing the working head on the milling.

The machine is the greatest difficulty in the design of the CNC with your own hands, the creation of a device is caused by which the working tool moves in three planes.

Partially solve the task will help carriages taken from a regular printer. The tool will be able to move in both planes. Choosing carriages for CNC machine is better from that printer that has large dimensions.

A similar scheme allows you to connect to the control machine in the future. Minus the fact that the CNC milling machine works only with wooden, plastic products, fine metal products. This is due to the fact that the printer carriages do not have the desired stiffness.

Attention must be given to the engine of the future unit. His role comes down to moving the working tool. This depends on the quality of the work and the possibility of performing milling operations.

A successful option for the self-made CNC of the freser is a stepper motor.

An alternative to such an engine is an electric motor, pre-improved and fitted under the standard standards.

Anyone using a stepper motor allows not to use a screw gear, it does not affect the possibilities of such a CNC on a tree. It is recommended to use for milling on such a strap-type belts. Unlike standard belts, they do not slip on the pulleys.

It is required to correctly design the milling mill of a future machine, for this you will need detailed drawings.

Materials and tools required for assembly

The total set of materials for the CNC machine includes:

cable 14-19 m long;
machining wood;
cartridge for cutter;
frequency converter having equal power with spindle;
bearings;
control board;
water pump;
cooling hose;
three stepping type engines for three axes of movement of the design;
bolts;
protective cable;
screws;
plywood, chipboard, wood slab or metal design to choose from as a body of the future apparatus;
soft-type clutch.

It is recommended to use a spindle with coolant with your own hands. This will allow not to turn off it every 10 minutes to compose. For work will suit homemade Machine CNC, its power is at least 1.2 kW. Optimal option Will be a capacity of 2 kW.

A set of tools required for the manufacture of an aggregate includes:

hammers;
isolent;
assembly keys;
glue;
screwdriver;
soldering iron, sealant;
bulgarian, it is often replaced with hacksaw;
passed, aggregate for welding, scissors, pliers.

Simple CNC machine with their own hands

Procedure for assembling machine

Homemade CNC Milling Machine is collected according to the scheme:

manufacture of drawings and device circuits with an indication of the electrical equipment;
buying materials containing the future homemade CNC machine;
installation of the bed, it will be attached to the engines, the work surface, portal, spindle;
installation of the portal;
installing Z axis;
fixation of the working surface;
installation of the spindle;
installation of the water-cooler system;
installation of the electrical system;
connecting the board, with its help the device is controlled;
software setup;
starting Start of the unit.

As a base for the bed, the material is taken from aluminum.

Stanna need to do with aluminum

Profiles from this metal are chosen with a cross section of 41 * 81 mm with a thickness of plates of 11 mm. The casing itself is connected using aluminum corners.

From the installation of the portal will depend on which thickness the product can handle the CNC machine. Especially if he made with his own hands. The higher the portal, the more thicker it will be able to process. It is important not to establish it too high, since such a design will be less durable and reliable. The portal moves along the X axis and carries the spindle on himself.

As a material for the working surface of the unit, an aluminum profile is used. Often take a profile having T-grooves. For home use Take, its thickness is at least 17 mm.

After the framework of the device is ready, proceed to the spindle setting. It is important to set it vertically, as it will require its adjustment, this is carried out for fixing the desired angle.

To install the electrical system require the presence of such components:

power Supply;
a computer;
stepper motor;
pay;
stop button;
engine drivers.

The LPT port is required for the system. In addition, it is established that managing the work of the device and allows you to answer the question of how to make one or another operation. Control is connected via engines to the milling machine itself.

After the electronics is installed on the machine, you will need to download drivers and the programs you need.

Common assembly errors

A common error when assembling a machine with numeric software control is the lack of drawing, but it is built on it. As a result, omission is omissions in the design and installation of the designs of the apparatus.

Often incorrect operation of the machine is associated with incorrectly selected frequency and spindle.

For the correct operation of the machine you need to choose the right spindle

In many cases, stepper motors do not receive proper nutrition, so they need to choose a special separate power supply.

It is necessary to take into account the fact that the installed electrical process and software Allows you to perform numerous operations on the device. of different levels difficulties. The CNC machine to do with their own hands to the middle service wizard, the aggregate design has a number of features, but with the help of drawings, it is easy to collect the details.

With CNC, with your own hands drawn up, it is easy to work, it is necessary to study an informative base, conduct a number of training work and analyze the state of the unit and the part. Do not hurry, pull moving parts or open CNC.
