CNC Spindle Encoder

The spindle encoder is mainly applied to CNC machines.The sychronis pulses from encoder is collected by CNC system and then the feeding data of tools are sent to servo motor to perform the motion.

  • Optical bearless spindle encoder

Application:CNC lathe


1.Long life and saving cost.The Grating component of encoder is directly connected to lathe spindle without the aid of flexible couplings,flange and synchronous pulley,which saves the cost of mounting accessory.The bearingless non-contact design reduces the mechanical loss and ensures higher life.
2.Reliable performance.American original parts and chips, and integrated photoelectric switch module are adopted by STS series encoder to ensure stable and reliable quality.The disc with special material could resist high temperature and three times of vibration than regular encoder.
