Problems solved by technology

[0002] The traditional grinding and polishing machine is often driven by a single motor, and the transmission of the upper and lower polishing discs and the inner and outer ring gears is realized through the gear transmission system. There are only two speed ratios between the upper and lower polishing discs and the planetary wheels, which limits the change of the processing trajectory of the double-sided polishing machine. Lack of precise control over speed
[0003] Chinese patent 02292538.4, a double-sided polishing machine planetary disk, the planetary disk is provided with three eccentric holes, and three separators are respectively placed in the three eccentric holes. Through the improvement of the planetary disk, the polishing yield can be partially improved , and improve the polishing efficiency, but because it still adopts the two-axis or three-axis transmission mode of the traditional grinding and polishing machine, it cannot realize stepless speed regulation, cannot adjust the pressure of the upper polishing disc, the processing stability is poor, and the efficiency is also low
