[0027] After polishing is completed, the lifting rod retracts, and then the electromagnetic enameled wire is powered off, the electromagnetic column loses its magnetic force, and the bearing ring becomes loose. The polished bearing ring is then pushed to the front of the conveyor belt on the other side by the multi-section telescopic rod on the side and then retracted. Then, another set of multi-section telescopic rods in front of the conveyor belt on the other side drives another push positioning block to push the polished bearing ring onto the conveyor belt for unloading, completing one round of processing.

[0028] When the polishing clamps are used for a long time and the polishing liquid is consumed, the moving mechanism drives them to move backwards so that the interval between the two groups of polishing clamps on both sides is just aligned with the two groups of adjusting front extension tubes, and the polishing liquid sprayed by them adheres to the surface of the cotton cloth layer for the next polishing process.
