[0002] Bearings are components that fix and reduce the load friction coefficient during mechanical transmission. When other parts move relative to each other on the shaft, they are used to reduce the friction coefficient during power transmission and keep the center position of the shaft fixed. Their main function is to support mechanical rotating bodies to reduce the mechanical load friction coefficient of the equipment during transmission. During the production process of bearings, the end faces of the bearings need to be polished so that the polished bearings can achieve better results when used. When polishing the end faces of bearings, existing bearing processing equipment uses a fixture to clamp the bearings, and then uses a motor to drive the grinding disc to rotate and polish the end faces of the bearings. After polishing one end face, the bearing needs to be removed from the fixture, flipped over, and re-clamped and fixed. Finally, the grinding disc is used to polish the other end face of the bearing.
