How to Build a CNC Machine

A good progress has been made in manufacturing industry as the computer is now used in most of areas. The use of computerized system has made it possible for CNC machines to work more accurate and faster. However, you can make some efforts to create your own CNC machine. Here is the guide.

Planning

Know well what equipment and devices should be prepared as they will be needed in the process. You must also inquire what method you are going to use to build your own CNC machine.

The first method is by modifying the existing tool by adding some additional parts to the machine and synchronizes it with the computer program. This method will save much time on your side since you do not need to create a new machine design. Besides, you can also keep the good performance of the machine in handling the material.

In case that you want to make the machine to be originally made on your own, use the second method. Starting from a scratch by making the design, then proceed to construct the machine.

Creating

Suppose that you choose the second method mentioned in previous point. Now, you have to make a head stock, which is a motor that powers the spindle (a metal cylinder) and mill. The point is to make a strong mount for the motor so that it can transfer the power to spindle. The spindle will be placed within the mount so that you need to think whether to use bearing or bushings.

Next, install a table of XY which functions as a moving surface that will go back and forth and side to side. You can use long screws and bolts to create this movement; the screws will rotate and lead the nuts to move laterally.

Modifying

In case you decide to modify your device rather than create a new CNC machine, you can start it by buying a mill. The mills are sold in various sizes, from small to large ones. While buying the mills, make sure you have determined the size as well as the types of the mills.
