Optical encoder types encoder

The spindle encoder on CNC machine tools generally has two functions: speed feedback and position feedback. Generally, CNC machine tools need thread processing. Each rotation of feed processing requires interpolation between the feed shaft and the spindle speed. Therefore, feedback speed and rotation direction are needed. When the tool is changed on the machining center, the spindle will stop at the fixed position every time by feeding back one revolution pulse signal. Above as...
