So, we propose to talk about how to make a CNC router with your own hands - details of the process, an overview of the required sets and kits, and also the general experience of the masters who have already done this. Let's reveal the secrets of assembling the machine with our own hands. So, you decided to make a CNC milling machine with your own hands, or maybe you just thought about it and do not know where to start work?

There are a huge number of advantages in having a CNC machine. Home-type machines can mill and cut almost all types of materials. Whether you are a craftsman or an amateur, it will open up a great horizon for your creativity.

The very fact that one of the machines may end up in a personal workshop is even more seductive.

General Information

There are a huge number of reasons why people want to build their own CNC milling machine with their own hands. As a rule, this happens only for the reason that we simply cannot afford to buy it in a store or directly from the manufacturer, and there is nothing strange about it, because their cost is extremely high. Or you can be like DIY craftsmen and have a lot of fun doing DIY work and creating something incredible, original. You can just do this to gain experience in mechanical engineering.


When the craftsmen first began to develop, think over and manufacture the first CNC milling machine with their own hands, it took about 1 day to prepare the project. Further, after that I had to buy elements, and then research was carried out.

And in the forums, as it turned out, can be found in different forums and sources, which led to the formation of new questions:

  • Are ball screws really required, or simple the studs and nuts will work just fine too.
  • Which linear bearing is better and is it worth buying?
  • What motors are required, and is it better to use a servo or a stepper?
  • Does the housing material deform very much when the huge size of the machine?

To great joy, some questions can be answered immediately at the expense of their engineering and technical base, which often remains after studying at the appropriate institution. And yet, many of the problems one might face could not be calculated.

You may need someone with practical experience and information on this subject. Naturally, on the forums on this issue, you can find many answers from different people, and many of which contradicted each other. In this case, further research will be required to find out which of the answers are true and which are just verbal rubbish.But you have to do this if you have a limited budget and want to take the best of what can be purchased with the available money. A similar situation is for most people who create a homemade CNC router machine.

Kits and assembly kits of CNC milling cutters

Yes, there are machine kits available for manual assembly work, but there have not been such kits yet, which could be tailored to specific needs. There is still no opportunity to make structural changes and machine varieties, and there are still many of them, and how do you know which one is right for you? No matter how good the instruction is, if the design is badly thought out, the final machine will remain bad. For this reason, it is required to be aware of what you are building and to understand all the details play a certain role.


This guide aims to prevent you from repeating the same mistakes that other masters have spent their precious time and money on. We'll go over all the components down to the bolts, looking at the pros and cons of all types of parts.

We will tell you about every aspect of design, and you will also learn how to create a CNC machine with your own hands. We walk you through the mechanics to software and everything in between.

Note that DIY CNC machine drawings offer few methods for solving specific problems. This can often lead to "sloppy" design or even unsatisfactory machine performance. For this reason, we suggest you read the following guide first.


Key Features

The first things to consider are:

Now let's talk about axes.

Base and X-axis

Here we will consider the following questions:

  • Design and construction of the main base or the base of the X-axis.

  • Breaking down different designs into separate elements.
  • Rigidly attached parts.
  • Partially fixed elements and so on.

Axis design Y

In this paragraph, we will consider the following questions:

  • Design and manufacture of the gantry axis Y.
  • Break different designs into elements.

  • Moments and forces at the port and so on.

How to assemble an axis Z

Here we will consider the following questions:

  • Design and assembly work along the Z axis.
  • Next, we consider the moments and forces on the axis.
  • Pay attention to the rails and guides, and also the distance between the bearings.
  • Select the cable channel.

Linear motion system

At this point, we suggest considering the following questions:

  • Study the systems in detail linear motion.
  • Finding the right system specifically for your type of CNC machine.
  • Design and build your own guides with a small budget.
  • Bushings and linear shaft or blocks and rails?

Mechanical drive components

CNC drawings do-it-yourself router needs to be considered in order to select the components of the mechanical drive:

  • A detailed overview of the drive parts.
  • Selection of suitable elements for your type of machine.

  • Servo motors or stepper motors.
  • Ball screws and screws pair.
  • Drive nuts.
  • Thrust and radial bearings.
  • Motor mount and coupling.

  • Gearbox or direct drive.
  • Gears and racks.
  • Calibration of screws relative to motors.

Engine selection

Here you need the following:

  • DIY CNC router - drawings, manufacturing technology Detailed overview of motors with device.
  • Varieties of CNC motors.

  • How stepper motors work.
  • Varieties of stepper motors.
  • How servos work.
  • Servo motor types.
  • NEMA standards.

  • Finding the right type of electric motor for your project.
  • Measurement of motor parameters.

Cutting table design

Here we will consider the following issues:

  • Designing and erecting your own tables with a small budget.
  • Perforated cutting layer.
  • Vacuum table.

  • Overview of the cutting table design.
  • The table can be cut with a wood router.

Spindle parameters

In this step, we will consider the following questions:

  • Overview of spindles with numerical programming security.
  • Functions and types.
  • Spending and pricing.

  • Installation and cooling options.
  • Installation and cooling options.
  • Cooling systems.
  • DIY spindle creation.
  • Calculates chips and cutting forces.

  • Finding the ideal feed rate.


Here we will consider the following issues:

  • Control panel.
  • Fuses and electrical wiring.
  • Switches and buttons.
  • Circles MPG and Jоg.

  • Power supply.

Parameters of the CP controller (programmed control)

In this step, consider the following questions:

  • Consider a CNC controller.
  • Controller selection.
  • Available functions.
  • Systems with a closed loop and an open loop.

  • Moderate cost controllers.
  • Building your controller from scratch.

Selection of software (software)

And it remains to consider the following questions:

  • Software review (software), which is associated with the CNC.
  • Select software.
  • CAM.

  • CAD software.
  • NC CONTROLLER software.

That's probably all. In fact, everything is not so difficult, the main thing is to figure it out.
