Compared with general mechanical parts, the bearing parts are short and thin rotary surfaces, the rotary body decides the machining machine tool relatively single, most of the lathe and grinder; short and thin determine its axial stiffness, the axial deformation can be ignored, the radial stiffness is poor, processing time to intensify the method to have special consideration.
Bearing parts of the vast majority of the surface to undergo grinding, grinding machining dimensions and geometric accuracy in μ m units, especially the raceway and rolling body of higher precision, need ultra precise machining or grinding.
Bearing parts are demanding, production process must be more. General bearing production needs to 20~40 road processes, more than more than 70 multi-channel.
The working surfaces of bearing parts are rotary forming surfaces, which are suitable for machining with molding process. such as the Ring raceway forging rolling and car grinding, are used in molding tool or mold plate processing.
