Equipment Highlights

Equipment Highlights

(1) The machine is controlled by three motors. The upper disk and the sun gear are driven by independent reduction motors, and the lower disk and the inner ring gear are driven synchronously. The control is flexible and the process range is wide;

(2) The inner ring gear is lifted and lowered through a cam mechanism, which is convenient to operate and flexible and reliable;

(3) pin-type traveling star wheel, wear-resistant, high service life;

(4) double sliding door type protection, convenient maintenance, reliable protection;

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

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

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

(8) Optional constant temperature cooling system to meet precision polishing.
