Rotary surface comparison and general machinery parts, bearing parts is short and thin body, rotator machine tools is relatively simple, the vast majority of lathes and grinding machines; short and thin to determine its axial stiffness, axial deformation can negligible, the radial stiffness of the poor, the processing time to step up to be a special consideration.
Rolling bearing parts, although the structure is simple, but technically demanding, hence several processing characteristics as follows:
1. Precision machining
To the bearing parts most of the surface after grinding, grinding size and geometric accuracy in μm units, especially the more accurate ferrule raceway and rolling element, need super finishing or grinding.
Multi-process machining
Bearing parts requirements, production processes is inevitable. The general bearing production takes 20 to 40 steps, and more up to 70 multi-channel.
3 forming
The working surface of the bearing parts are rotary molding surface, the molding method suitable for processing. Ferrule the of forging rolling with car grinding raceway, are 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 technology to improve the level of mechanization and automation, bearing company generally bearing types and varieties mass production, even the establishment of specialized automatic production line or pipeline
