Tips: Stepper motor for CNC machine

CNC machine is generally composed of control media, CNC devices, servo systems, and the machine itself. The first step in the application of stepper motors on CNC machine is to input the compiled program to the CNC system through the control medium. It is actually to convert the compiled program into digital information that can be recognized by the machine.

Then the stepping motor converts the converted digital information into pulse signals through the numerical control device and transmits it to the servo system. The servo system converts the pulse signal from the numerical control device into the precise movement of the moving parts of the machine.

The accuracy of CNC machine is affected by the mechanical parts and transmission components of the machine itself, and the working condition of the servo system directly affects the accuracy of the CNC machine. The so-called servo system refers to an automatic control system that takes position and speed as the control object, also known as a drag system or a follow-up system. The servo system accepts the feed pulse command generated by the interpolation device or interpolation software, and after a certain signal conversion, voltage and power amplification, it is converted into the motion of the machine table relative to the cutting tool.
