CNC Parts

There are two types of motors; stepper or servo motors. This is how we create motion. These motors drive our various axis on our CNC machine. While we are moving our axis, there is generally a cutting tool of some sort removing material. This is the machining process coupled with CNC.

Here is a brief description of the two types of motors generally used in CNC:

Stepper motors:

Simple design

Easy to use

Generate torque at low rpm

Do not know their position in relation to the program

Servo Motors:

Generate torque at high RPMs

Generally need gearing of some sort to be effective

More sophisticated

Can maintain their relative position, thus, they can be more accurate

There are a number of parts that go into a CNC Machine. You need a computer, controller and then the machine. The machines will also consist of various parts.

Then CNC Machine will have Parts like:

Ball Screws

Linear Rails

Gears

Rack

Steel

Motors

What is a Machine Controller?

Controllers generally stand alone near the CNC machine. They act as a translator between your control computer and your CNC machine. Generally, they add quite a bit of cost to a CNC machine as well. Controllers can cost anywhere from $1000-$20,000 or more depending on their sophistication.
