Compared with the usual mechanical parts; the bearing parts are short and thin inverted outer bodies; the reversing body determines that the machining machine is simpler; most of them are lathes and grinding machines, and the short and thin resolution determines the axial stiffness; The deformation can be neglected; the radial stiffness is poor; the hurry in processing should have special consideration.
Rolling bearing parts, although the layout is simple; but the skill requirements are high; therefore, there are several processing features as follows:
1. Most of the fine-machined bearing parts must be ground by grinding; the grinding scale and a few precisions are in Î¼m; especially the raceway and roll of the ferrule are more precise; super finishing or grinding is required.
2. The demand for multi-process machining of bearing parts is high; the production process must be more. Usually the bearing production requires 20 to 40 processes; more than 70.
3. The working appearance of the formed and processed bearing parts is reversed molding surface; it is suitable for processing by molding method, such as casting rolling and grinding of ferrule raceway; it is processed by forming tool or anti-type plate.
Others; most of the bearings are standardized products; the same type of bearings are in great demand; in order to improve productivity, reduce costs, ensure quality and extensive selection of new skills, improve mechanization and automation levels; bearing companies usually according to bearing type And types of large-scale production; or even set up a special automatic line or assembly line for production.
