[0002] Bearing steel is the steel raw material used in the existing technology to produce steel parts such as balls, rollers and bearing rings. Bearing steel has high-quality and uniform hardness and wear resistance. In the production and forming process of bearing steel, there are extremely high requirements on the uniformity of the chemical composition of bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides. It is one of the most stringent steel types in all steel production requirements. After the casting of the bearing steel is completed, the appearance of the bearing steel is cylindrical. However, during the forming process of the bearing steel, there are often some burrs and other defects on the surface of the bearing steel. In order to facilitate the subsequent processing of the bearing steel, people often use belt grinding equipment to grind the surface of the bearing steel during the processing of the bearing steel.
