[0002] As a bearing that can bear both radial load and axial load at the same time, deep groove ball bearings have the advantages of simple structure, low friction coefficient, and certain self-aligning ability. They are widely used in many fields of modern machinery manufacturing. When processing deep groove ball bearings, the accuracy of the bearing raceway directly affects the stability and safety of the bearing during rotation. If the raceway surface is not smooth enough, it will cause uneven friction between the ball and the raceway, thereby affecting the rotation accuracy of the bearing. Therefore, when processing deep groove ball bearings, grinding and polishing of the raceway is an unavoidable processing step. With the continuous advancement of the automation process in the manufacturing industry, the polishing of the deep groove ball bearing raceway is often carried out with a special raceway polishing device to ensure the stability of the surface quality of the deep groove ball bearing raceway.
