Equipment Highlights

Equipment Highlights

● This series of equipment belongs to the four planetary gear train motion principle of grinding (polishing) machine tools.

● Adopt internal gear ring lifting mode; adopt PLC control, flexible and reliable control mode.

● Different types of equipment in this series are designed with different numbers of drive motors. 8436B, 8432E and 13B-9L are all driven by two motors, 8432C is driven by three motors and 18B is driven by four motors.
