And general machinery parts compared, bearing parts is rotary surface body is short and thin, axisymmetric body determines the machine is single, the vast majority of lathes and grinders; short and thin determines its axial stiffness, axial deformation can be ignored, poor radial stiffness, stepping up the method and time to have special consider.
Rolling bearing parts, although the structure is simple, but the technical requirements is very high, so there are several processing characteristics:
1, precision machining
Bearing parts most surface after grinding, grinding the dimensional and geometric accuracy in M units, especially the ring raceway and rolling body of higher precision, ultra-precision machining or grinding required.
2, multiple processes
Bearing parts demand is high, the production process is more. General bearing production needs 20 ~ 40 working procedure, the more than 70 multichannel.
3, processing
The working surface of bearing parts are rotary forming surface, suitable for processing molding method. Such as forging forging and car raceway grinding, are used in forming cutter or prevent plate processing.
In addition, the vast majority of bearings are standard products, bearing the same model in great demand, in order to improve productivity, reduce costs, ensure the quality and the extensive use of new technologies, improve the level of mechanization and automation, bearing company is produced in large quantities by the bearing type and variety, and even set up special line or assembly line production.
