And general machinery parts, bearing parts is short and thin surface of the rotary body, rotary decision of a single machine tools, the vast majority of lathes and grinding machines; short and thin determines its axial stiffness, axial deformation can negligible, less radial stiffness, the process of stepping up to be a special consideration.
KOYO bearings parts although the structure is simple, but technically demanding, and thus there are several processing features:
1, precision machining
Most of the surface of the bearing parts to go through the grinding, grinding size and geometric accuracy μM, higher accuracy especially rings raceways and rolling elements, need super finishing or grinding.
2, multi-process machining
Bearing parts requirements, the inevitable production process. The general bearing production process takes 20 to 40, and more than 70 multi-channel.
3, molding processability
The KOYO bearing parts work surface rotary forming surface, suitable for use molding process. Such as forging ring raceway rolling car grinding, are based on the molding tool or anti-plate processing.
In addition, the vast majority of bearings are standardized products, the same type of bearing great demand, in order to increase productivity, reduce costs, ensure quality and widespread adoption of new technology to improve the level of mechanization and automation, KOYO bearings Bearings Model and varieties for mass production, and even the establishment of specialized automatic line production pipeline.
