Rolling type, structure type, tolerance level, technical requirements, materials and quantities of the different, the basic production process is not exactly the same.
Processing of the various bearings main parts:
1. Process of the rings: the bearing inner ring and outer ring of processing according to the different raw materials or rough form is different, where the car before processing process can be divided into the following three, the whole process: the bar or tube material (some bar stock subject to the forging and annealing, normalizing) ---- car processing ---- Heat Treatment ---- grinding processing ---- lapping or polishing of the final inspection of the ---- part ---- the antirust ---- storage ---- (to be co-suite with>
2. The process of the ball, the ball of processing according to the status of raw materials vary, which fell cut or ball of light before the process can be divided into the following three, before the heat treatment process can be divided into the following two kinds, the whole process: the bar or wire rod cold red (some bar cold red need to red ring and annealing) ---- setback cut, coarse, soft grinding or ball of light ---- Heat Treatment - --- ---- grinding hard grind ---- lapping or grinding ---- final inspection packet ---- anti-rust packing ---- storage <to be co-suite with>.
3. Process roller processing according to the different raw materials, before the heat treatment process can be divided into the following two, the whole process is: after the car processing of bar or wire rod for cold heading string band and soft tactics ---- Heat Treatment ---- string soft spot ---- coarse grinding outer diameter ---- coarse grinding end ---- end face grinding ---- finely ground outer diameter ---- end of grinding the outside diameter ---- end packet inspection ---- anti-rust packing ---- storage (to be co-suite with>.
4. The process of the cage to cage the process according to different design and raw materials can be divided into the following categories:
(1) strip → shear → punching → shaping and finishing of metal forming → → pickling or shot blasting or string light → final inspection, anti-rust → packaging → warehousing (to be co-suite with)
(2) physical cage process: the physical cage processing vary according to raw materials, or bad hair different, which type of car before processing can be divided into the following four rough, the whole process: the bar tubing, forgings, castings ---- car inside diameter, outside diameter, face, chamfer ---- drilling (or broaching, boring) ---- pickling ---- final inspection ---- rust, packaging ---- warehousing "to be co-suite with>.
