And general machinery parts, bearing parts are short and thin body of the rotary surface, rotary decided to compare a single processing machine tools, the vast majority of lathes and grinding machines; short and thin determine the axial stiffness, axial deformationcan be neglected, poor radial stiffness, so as to have special consideration of the processing to step up method.

Rolling bearing parts, although the structure is simple, but technically demanding, and thus has the following processing features:

(1) Precision Machining

Most of the surface of the bearing parts after grinding, grinding size and geometric accuracy in μm units, especially the ring raceway and rolling element accuracy, be super finishing or grinding.

(2) multi-processing procedures

The requirements of the bearing parts, production processes must. General bearing production takes 20 to 40 processes, and more up to more than 70.

(3) Forming

The working surface of the bearing parts are rotary molding surface, suitable for molding processing. Such as the forging of ring raceway rolling car grinding, and are based on the forming tool or anti-plate processing.

In addition, the vast majority of bearings are standardized products, the same type of bearing requirements, in order to increase productivity, reduce costs, ensure quality and widespread adoption of new technologies, improve the level of mechanization and automation, bearing company by bearing type and variety. for mass production, and even the establishment of specialized automatic production line or assembly line production.
