When the polishing is completed, the telescopic cylinder 4 drives the motor 5 to reset, and the pushing cylinder 2 continues to move to push the bearing ring 10 into the discharging channel 14 for discharging, and then resets. Then the blocking cylinder 3 resets, and the bearing ring 10 in the vertical dropping channel 11 falls, and the above steps are repeated. In this cycle, the bearing ring is continuously polished, which helps to improve the production quality of the bearing.
