(2) The inner gear ring realizes precision lifting and automatic adjustment through the ball screw pair;

(3) The system adopts full closed-loop control, multiple sensor feedback, real-time monitoring and adjustment of processing parameters;

(4) automatic detection, feedback and compensation of processing pressure, digital input pressure parameters;

(5) equipped with constant temperature cooling system, grinding fluid temperature by the sensor automatic detection feedback, automatic adjustment of grinding fluid temperature;

(6) Three-stage filtration system can effectively separate impurities and avoid secondary scratches;

(7) Flexible loading system, precision electric proportional valve control, stable and reliable pressure, uniform pressure and high precision;

(8) The upper panel is equipped with a safety self-locking device, which is interlocked with the program to ensure the safety of operation;

(9) touch screen man-machine interface, PLC control, friendly interface, large amount of information.
