The process of grinding the teeth of a gear to a certain precision by using a CNC gear grinding machine is called grinding. According to the structure of the gear components, the gear grinding method is divided into internal gear grinding and external gear grinding. By grinding the gears of the reducer, the transmission accuracy of the reducer will be greatly improved, the transmission efficiency will be improved, and the operation time of the reducer will be reduced to a certain extent. The noise and vibration can prolong the service life of the reducer!
