1. The processing process of the ring: the processing of the inner ring and outer ring of the bearing is different according to the different forms of raw materials or blanks. The process before the car processing can be divided into the following three kinds. The whole processing process is: Bar stock or tube (some bar need to the forging, annealing, normalizing) - car processing, heat treatment, grinding, grinding or polishing parts - final inspection - rust - storage - (stay close set of assembly >
2. The processing process of steel ball, the processing of steel ball is also different according to the state of raw materials, the process before cutting or light ball, can be divided into the following three kinds, the process before heat treatment, and can be divided into the following two kinds, the whole process is: Bar or wire cold blunt (some bar after cold blunt still need band and annealing), sharp cutting, coarse grinding, hard or soft grinding ball - heat treatment - grinding, fine grinding, lapping and grinding - final inspection group - rust, packaging, warehousing < to sets of assembly >.
3. Roller processing process Roller processing varies according to the different raw materials, among which the process before heat treatment can be divided into the following two types, the whole process is: Rod furnace processing or wire cold heading after string band and soft grinding, heat treatment, series of soft point, coarse grinding, coarse grinding diameter end - the end face grinding, fine grinding diameter - end mill diameter - final inspection group - rust, packaging, warehousing (stay in sets of assembly >.
4. The processing process of cage According to the different design structure and raw materials, the processing process of cage can be divided into the following two categories:
(1) sheet metal → shear → punching → stamping → shaping and finishing → pickling or shot peening or light series → final inspection → rust prevention, packaging → storage (to be assembled)
(2) the processing process of the solid cage: the processing of the solid cage is different according to the different raw materials or wool. The car can be divided into the following four blank types before processing. The whole processing process is: Bar, pipe material, forging, casting, car inner diameter, outside diameter, end face, chamfering, drilling (or pull holes, boring), pickling, final inspection, anti-rust, packaging, warehousing < stay close set of assembly >
