1. Rings of the processing process: bearing inner ring and outer ring processing according to the raw materials or blank form of different, which can be divided into the following three processes before the turning process, the whole process is: rod or tube material (some rods need to be forging and annealing, normalizing) ---- car Processing ---- heat treatment ---- grinding process ---- finishing or polishing ---- parts final inspection ---- rust ---- storage ---- (to be assembled together>
2. Steel ball processing process, the processing of steel balls, the same according to the state of raw materials are different and different, which can be divided into the following three kinds of process before the thwarting or light ball, heat treatment process, can be divided into the following Two, the entire process for: rod or wire cold punching (some rods after cold punching also need to punch the ring belt and annealing) ---- chipping, rough grinding, soft grinding or light ball ---- heat treatment ---- hard grinding ---- grinding ---- grinding ---- grinding ---- fine research or grinding ---- final inspection grouping ---- rust, packaging ---- into the warehouse 〈To be assembled together〉.
3. Processing of rollers The processing of rollers varies according to the different raw materials, in which the process before heat treatment can be divided into the following two kinds, the whole process is as follows: rod turning or wire cold heading after stringing the ring belt and soft grinding ---- heat treatment ---- stringing the soft point ---- rough grinding OD ---- coarse grinding face ---- end grinding face ---- end grinding face ---- fine grinding OD ---- final grinding OD ---- final inspection grouping ---- rust prevention, packaging ---- into the warehouse (to be combined set assembly〉.
4. Processing of cage The processing of cage can be divided into the following two categories according to the design of the structure and raw materials:
(1) sheet → shear → punching → stamping → shaping and finishing → pickling or shot blasting or string of light → final inspection → rust prevention, packaging → warehousing (to be fitted with the assembly)
(2) the processing of the solid cage: solid cage Processing, depending on the raw materials or bad different and different, which can be divided into the following four types of blanks before the car processing, the entire process: rod, tube, forging, casting ---- car ID, OD, end face, chamfering ---- drilling (or pulling holes, bores) ---- pickling ---- final inspection ---- rust, packaging ---- storage (to be combined with the set of assembly〉. Second, rolling SKF bearing assembly process:
Rolling INA bearing parts such as inner ring, outer ring, rolling body and cage, etc., after passing the inspection, into the assembly workshop for assembly, the process is as follows:
Parts demagnetization, cleaning, inner and outer rolling (groove) channel size group selection → Combined sets → Check the clearance → riveted to the cage → Final Inspection → demagnetization, cleaning → rust, packaging →
Parts demagnetized, cleaning, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging, packaging.
