Analytic: production technology of rolling bearing components

Compared with general machinery parts, bearing parts is short and thin the rotary surface of the body, of rotors decided the machine is single, the vast majority of lathe and grinder; Short and thin determines its axial rigidity is good, the axial deformation is negligible, radial stiffness is poorer, processing methods of stepping up to have a special consideration. Rolling bearing parts, although has simple structure, high technical requirements, and therefore has the following several processing characteristics: 1, the precision machining bearing parts most of the surface to after grinding, grinding size and geometric accuracy are in microns, especially ring raceway and rolling body of higher precision, superfinishing or grinding processing. 2, high bearing parts processing various process requirements, the production process will be more. General bearing production need 20 ~ 40 working procedure, much more than 70. 3, forming bearing parts of the surface of the work are rotary forming surface, suitable for molding in processing. Such as forged ring groove rolling mill and car, is the forming tool or prevent plate processing. In addition, the vast majority of the bearing are standardized products, the same type of bearing demand is very big, in order to improve the productivity, reduce costs, ensure the quality and the widespread adoption of new technology, improve the level of mechanization and automation, bearing company usually is according to the bearing types and varieties for mass production, even can establish special automatic line or lines of production.
