Encoders play important role in CNC machines on which the machining accuracy depends, especially the MPG---Manual Pulse Generator. The handwheel as a common manual operation part is widely used in the CNC lathe processing center and measuring center. It brought a lot of convenience to the lathe operator the MPG handwheel can control workpieces accurately and quickly.
The CNC machine industry typically uses encoders for the following functions:
moving horizontal sliders
Controlling workpiece to move slider and tailstock.
Correcting of lathe origin
