CNC milling machine with hands. Build homemade milling CNC Machine milling machine CNC with their own hands

The purpose of this project is to create a CNC desktop. It was possible to buy a finished machine, but its price and sizes did not suit me, and I decided to build a CNC machine with such requirements:
- Use simple tools (only needed drilling machine, band-saw and hand tool)
- Low cost (I was focused on low cost, but still bought items about $ 600, it can be significantly saved by buying elements in the respective stores)
- Small occupied area (30 "x25")
- Normal workspace (10 "along the X axis, 14" along the Y, 4 axis along the z axis)
- high speed Cutting (60 "per minute)
- Small number of elements (less than 30 unique)
- Available elements (all elements can be bought in one business and three online stores)
- the possibility of successful plywood treatment

Machines of other people

Here are some photos of other machines assembled on this article.

Photo 1 - chris with a friend gathered the machine, cutting out the details of 0.5 "acrylic with a laser cutting. But everyone who worked with acrylic knows that laser cut It's good, but acrylic does not tolerate drilling, and there are a lot of holes in this project. They did good work, more information You can find in Chris's blog. I especially liked the manufacture of 3D object using 2D cuts.

Photo 2 - Sam McCaskill did a really good tabletop with CNC. I was impressed that he did not simplify his job and cut off all the elements manually. I am impressed with this project.

Photo 3 - Angry Monk "S used DMF parts cut with laser cutter And engines with gear-toothed transmission, converted into engines with screw.

Photo 4 - Bret Golab "S assembled the machine and set it up for working with Linux CNC (I also tried to do it, but could not because of difficulty). If you are interested in its settings, you can contact him. He made a great job!

I am afraid that I have insufficiently experience and knowledge to explain the foundations of the CNC, but on the forum of the site CNczone.com there is an extensive section dedicated to homemade machines, which helped me very much.

I sought to use popular tools that can be purchased in a regular shop for masters.

Power tools:
- Ribbon saw or jigsaw
- drilling machine (drills 1/4 ", 5/16", 7/16 ", 5/8", 7/8 ", 8mm (about 5/16")), also called q

Head unit --- (additionally)
-I installed Dremel on my machine, but if you are interested in 3D printing (for example, REPRAP) you can install your device.

Print templates

I had some experience of the jigsaw, so I decided to glue patterns. It is necessary to print PDF files With templates placed on a sheet, stick a sheet on the material and cut the items.

File name and material:
All: CNC-CUT-SUMMARY.PDF
0.5 "MDF (35 8.5" x11 "sheets with templates): CNC-0.5MDF-CutLayout- (Rev3) .pdf
0.75 "MDF: CNC-0.75MDF-CutLayout- (Rev2) .pdf
0,75" aluminum tube: CNC-0.75ALUM-CutLayout- (Rev3) .pdf
0.5 "MDF (1 48" x48 "Sheet with templates): CNC- (one 48x48 Page) 05-MDF-CutPattern.pdf

Note: I apply CorelDRAW drawings in the original format (CNC-CorelDRAWFormat-CutPatterns (Rev2) Zip) for those who would like to change something.

Note: There are two variants of files for MDF 0.5 ". You can download the file with 35 pages 8.5" x11 "(CNC-0.5MDF-CutLayout- (Rev3), PDF), or file (CNC- (one 48x48 page) 05- MDF-CutPattern.pdf) with one sheet 48 "x48" for printing on a widescreen printer.

Step by step:
1. Download three PDF files with templates.
2. Open each file in Adobe Reader
3. Open the print window
4. (Important) Disconnect page scaling.
5. Check that the file is accidentally scaled. The first time I did not do it, and printed everything on a scale of 90%, as stated below.

Sticking and sawing elements

Stick printed patterns on MDF and on the aluminum pipe. Next, just cut the part along the contour.

As mentioned above, I accidentally printed the templates on a scale of 90%, and did not notice this before the start of drinking. Unfortunately, I did not understand this before this stage. I stayed with templates on a scale of 90% and, moving through the whole country, I got access to a full-size CNC. I could not stand and cut items with this machine, but I could not drill them with back side. That is why all elements in photographs without pieces of the template.

Drilling

I did not consider how much precisely, but there are many holes in this project. Holes that are worn on the ends are especially important, but do not take the time for them, and you will have to use the rubber hammer.

Places with holes in the lining on each other is an attempt to make grooves. Perhaps you have a CNC machine on which it can be done better.

If you reached this step, I congratulate you! Looking at a bunch of elements, it's pretty difficult to imagine how to assemble the machine, so I tried to do detailed instructionssimilar to the instructions for LEGO. (Announced PDF CNC-ASSEMBLY-INSTRUCTIONS.PDF). Pretty interesting look step-by-step photos assembly.

Ready!

Machine ready! Hope you did and launched it. I hope that the article is not missed important details and moments. Here is a video, which shows the cutting machine of the pattern on the pink foam.

So you decided to build homemade CNC The milling machine or maybe you just think about it only and do not know where to start? There are many advantages in CNC machines. Homemade machines can produce milling and cutting almost all materials. Whether you are an amateur or master, it opens up big horizons for creativity. The fact that one of the machines can be in your workshop is even more seductive.

There are many reasons why people want to build their own CNC milling machine with their own hands. As a rule, this is because we simply cannot afford to buy it in the store or from the manufacturer, and there is nothing surprising in this, because the price is rather big. Or you can be similar to me and get a lot of pleasure from of own work and creating something unique. You can just do this to get experience in mechanical engineering.

Personal experience

When I first began to develop, think over and make the first CNC card with my own hands, about one day went to create the project. Then, when I started buying parts, I spent a small study. And found some information in various sources and forums, which led to the emergence of new questions:

• I really need ball-screw pairs, or ordinary studs and nuts will work quite normally?
• What a linear bearing is better, and can I afford it?
• What parameters do I need, and better use a steppet or servo drive?
• Is the case material deformed too much with a large size of the machine?
• Etc.

Fortunately, I was able to answer some of the questions thanks to my engineering base left after studying. However, many of the problems that I would face, could not be calculated. I just needed someone with practical experience and information on this issue.

Of course, I got a lot of answers to my questions from different peopleMany of whom contradicted each other. Then I had to continue the research to find out what answers are standing, and which are garbage.

Every time I had a question, the answer to which I did not know, I had to repeat the same process. For more, this is due to the fact that I had a limited budget and wanted to take the best of what you can buy for my money. The same situation in many people creating a homemade milling machine with CNC.

Kits and kits for assembling CNC mills with hands

Yes, there are accessible sets of machine tools for manual assembly, but I have not yet seen any one that could be adjusted under certain needs.

It is also not possible to make changes to the design and type of machine, and there are many of them, and how do you know which one is suitable for you? No matter how good the instruction is if the design is thought out badly, then the ultimate machine will be bad.

That's why you need to be aware of what you build and understand what role each detail plays!

Guide

This guide is aimed at not giveing \u200b\u200byou to make the same mistakes that I spent my precious time and money.

We will look at all the components up to the bolts, looking at the advantages and disadvantages of each type of every detail. I will tell you about each aspect of the design and show how to create a CNC milling machine with your own hands. I will conduct you through the mechanics for software and everything intermediate.

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

Stanina
The bed of our machine is made of plastic 11-12mm thick. The material is not critical, you can use aluminum, organic glass Phaneur and any other affordable 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
Steel rods with a diameter of 12mm are used as the guides, length 200mm (on the Z 90mm axis), 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 at the top have 4 threaded holes For mounting the table and the zode of the Z axis.

Z Caliper
The Z axis guides are attached to the caliper x through the 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. 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:
Nuts can also be made of cast iron, it is not worth using other materials, the screws can be bought in any construction store and trim under their 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

Power Supply
A block of 12 volt 3a was used as a power source. 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.

Controller
The controller was assembled in total on 3 microcircuits of the 555TM7 series. The controller does not require firmware and has a fairly simple principal schemeThanks 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).

Driver for stepper motors
To control the stepping motor, a driver is used, 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. Detailed description And the instruction on the use of the program is on.

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.

According to the site: vri-cnc.ru

In the home workshop it is desirable to have the simplest table machines - drilling, grinding, etc. But if you need to perform accurate work, you can not do without a milling unit. To do this, you can make a simple CNC with your own hands. This can be done in two ways:

The homemade CNC machine is required for accurate drilling or circumcision, as well as turning parts.

• buy a set for the manufacture of such a design;
• make such a mill.

The first way is associated with certain financial expenses. Branded machines for home use Have a relatively high price and not for everyone to pocket.

CNC requires certain knowledge and possession tool to create it.

How to start designing a homemade milling mill?

First you need to select the appropriate scheme of the unit. As a basis, you can take a regular drilling machine, only instead of drill to use a milling cutter. Naturally, it will be necessary to think through the mechanism of its movement in three planes. Usually for small units use recycled carriages from the printer, with which the working tool can move in two planes. This is beneficial and in terms of connecting software to work in automatic mode. But such structures have one drawback - they allow processing wood, plastic and thin sheets of metal (1-2 mm).

Therefore, for more serious works, the CNC mill must have stepper engines of high power. They can be made by finalizing the standard electric motors of this class, which will allow you to abandon the use of screw transmission while preserving all its advantages. To transfer efforts to the shaft, the best uses toothed belts.

When using self-made carriages to move the working tool, you can use parts from large printers. Below will be described one of homemade structures like type.

Production of CNC milling

This machine for its design resembles samples of industrial aggregates. The basis of it is the low beam of the rectangular section, directly fixed on the guides. This allows you to obtain the desired stiffness of the design and minimize welding work when creating a milling mill.

As the basis of the metal square trumpet with a side of 75-85 mm. For mounting to the guides, it is necessary to apply the soles of the rectangular type 65 x 25 mm. This allows you to abandon the welding at this stage of work and will help with the exact setting of the mill. It is necessary for the right corners of 90 degrees. The main beam and sole are connected using 4 M6 screws, which must be tightened until it stops to get the desired rigidity. This will eliminate the backlash, although the deflection of the guides are possible with a large load and problems in the sliding bearings (any suitable, even Chinese) can be applied.

The vertical lifting of the working tool is carried out using the screw transmission, and the toothed belt is used to return to rotation on print. This makes it possible to avoid beats, lower the center of gravity of the aggregate and save space. The vertical axis itself is made of aluminum stove. It must be processed on the milling machine in size required for homemade machine. If the home workshop has a muffle furnace, then it can be pulled out of aluminum.

Over the axis it is necessary to install two stepping motors: the first rotates the chassis screw of the vertical displacement, and the second provides a movement horizontally. Rotation is transmitted using belts. Some details must be ordered from tokar if there is no own lathe.

After the manufacture of all items and assembly, you need to check the CNC mill in operation using manual control. After that, you need to do stepping controllers and software. If there are no relevant knowledge, then you can contact the company that has good programmers.

Maybe you may need a metal bed or artificial stonewhich is better to order on the desired size.

What step engines can have a homemade CNC?

These are the most important elements of the future mill.

In order to get such electric motors, you need to disassemble old matrix printers (for example, Epson). Inside such devices there are two stepping motors and good steel rods from tempered steel. To build a milling mill, you need to have 3 electric motors, so you will have to disassemble 2 printer.

In order to simplify the production of operations on a homemade machine, it is best to apply engines with 5-6 control wires: they have a good torque, and easily work with them. For proper program settings, you need to know the number of their degrees per step, operating voltage and winding resistance.

To drive on a homemade CNC, a nut and a hairpin is usually used. To secure the shaft of the stepper motor, a piece of a thick-walled rubber cable is usually used, with its help the electric motor is attached to the heel. The fixators use homemade sleeves with screw. They are made from nylon, applying a drill and a file.

For many home masters, it may seem that is somewhere on the verge of fiction, since this equipment is complex in constructive, technical and electronic device.

Meanwhile, having the appropriate drawings at hand, all required Material and tool, mini milling homemade machine on a tree, equipped with CNC, can be made with your own hands.

Of course, for this you will have to spend certain efforts, including financial, but there is nothing impossible, and if correctly and with knowledge of the case approach the solution of this issue, the homemade table milling machine on the stage of mining with the CNC block will be able to make it House master.

As you know, such a mini wood unit is characterized by the accuracy of the processing, simplicity of management of all work processes, as well as high quality finished product.

Currently, the homemade table-milling machine with CNC in the mini execution for wood work and other materials can be several ways.

First of all, you can purchase a special set to collect this type of construction, and you can spend all the necessary work with your own hands, receiving at the exit ready product With high quality processing.

If the solution is made all necessary work By designing and assembling a mini-milling machine for woodworking and other materials with CNC, it is necessary to begin with the choice of the most optimal scheme of the future unit.

In this case, as the source equipment, you can take a small old boring machine and replace the working body in the form of drill directly on the mill.

Be sure to thoroughly think about how the mechanism is arranged responsible for the necessary movement in three independent planes.

You can try such a mechanism from recycled carriages from the old printer, which will provide an opportunity to ensure the movement of the working mill in two planes.

Here it will be possible to simply connect the necessary softwareThat makes it possible to make a homemade CNC Milling Machine automatic, but this design will be able to work only on wood, plastic or thin metal.

To make a homemade milling machine, collected with their own hands, was able to perform more serious operations, it must be equipped with a stepper motor with high power.

You can get this type of engine from the standard version of the electric motor due to a small refinement. This will fully eliminate the use of screw transmission, while all its advantages will be preserved in full.

The required effort on the shaft in the homemade unit is best transmitted through gear straps.

In the event that, to ensure the necessary movement of the working cutter in the self-made milling machine with CNC, it is decided to use homemade carriages from printers, then it is better for these purposes to take these devices from large printer models.

When creating a CNC milling unit with your own hands, special attention should be paid to the manufacture of the milling mechanism, which requires the relevant drawings.

Assembling milling machine

As the basis of the self-made milling machine, it is best to take a rectangular beam that should be firmly fixed on the guides.

The whole design should have high rigidity, while better if welding work will be minimized.

The fact is that in any case, the welding seams are susceptible to destruction and deformation at certain loads, when the machine operation, it will be subjected to the machine, including vibrations, which can adversely affect these fastening elements, which, in turn, will lead To a failure in the settings.

The beam and fastening elements to enhance stiffness are recommended to fasten using certain diameter screws.

This should completely eliminate the possible backlash when operating a CNC milling machine, as well as the deflection of guides with serious loads.

At the same way, the principle is collected with their own hands and homemade milling engraving machineEquipped with CNC. About the process of assembly with their own hands functional machine The milling type with CNC is described in detail on the video below.

In the design of the unit is necessary in obligatory Provide a lifting of the working tool in a vertical position, for which it is recommended to use the screw gear.

In turn, for the necessary return of rotation directly to the undercarriage should use a toothed belt.

The vertical axis, which is also a mandatory element of any CNC milling machine, make an aluminum plate.

It should be accurately adjusted in size, which were obtained at the design of the unit and are listed in the relevant drawings.

At home, throwing out the vertical axis using a muffle plate, and in this case, aluminum should be taken.

After that, directly on the housing immediately for the axis should be mounted two stepping type engines, one of which will be responsible for the horizontal movement, and the second, respectively, for the vertical.

All rotation must be transmitted through belts. After all the elements are in their places, the homemade milling machine should be checked in operation when manual control, and when identifying shortcomings, eliminate them in place.

A little about stepper motors

Any CNC unit, including the engraving machine, is necessarily equipped with stepplightened type electric motors.

When assembling self-made milling equipment with CNC, the engines from old matrix printers can be used as such a motor. Most matrix printers have two such elements with sufficient power.

In addition, steel rods made from durable steel can also be used in matrix printers, which can also be used in a homemade machine.

In this case, it should be noted that for the assembly of such an aggregate, you will need three separate stepping type engines, and therefore you have to search and disassemble two matrix printer.

It is better if such engines will have about five separate control wires, since in this case the functionality of the homemade machine will increase several times.

Selecting the stepping type engines for the self-made milling machine with CNC, it is necessary to figure out the number of their degrees one step, as well as the operating voltage and winding resistance.

This will subsequently help to properly configure all the hardware software.

Running a stepped type motor shaft is best with a rubber cable with thick winding. It will help and when attaching the engine itself directly to the heel.

Perform the fixators can be made of screw bushings from your own hands. To do this, take a nylon, and as a drill and file tool.

About how to make the engraving milling machine with a CNC block, described in detail on the video below.

Electronic support

The main element of any machine equipped with CNC is its software.

In this case, you can use self-made, which will include all the necessary drivers for installed controllers, as well as stepper motors, and in addition, standard supply blocks.

This requires a LPT port. It will also be necessary to think about working programwhich will ensure not only control, but also the management of all the necessary modes of work.

Directly, the CNC unit itself should be connected to the milling unit through the above port necessarily through the installed motors.

Selecting the necessary software for the homemade machine, it is necessary to bet on the one that has already managed to prove its stable work and has huge functionality.
Video:

It should be remembered that the electronics will mainly affect the accuracy and quality of all operations performed on CNC equipment.

After all the necessary electronics are installed, you need to download all the software and drivers required for the operation of the wall-milling machine.

Further, immediately before the machine starts to be operated according to its direct intended purpose, the electronic software should be checked and, if necessary, to eliminate all the identified shortcomings.

All the above-described assembly operations with their own CNC milling machines are suitable for creating a self-made coordinate and plant unit, as well as many other equipment of this class.

In any case, if all the work on the assembly of the milling unit, equipped with CNC, is performed correctly and in accordance with technology, homemade Masters There will be an opportunity to perform many of the most complex operations, both for metal and wood.

On how to make an independent milling machine with a CNC unit, described in detail on the video in our article.
