1. Processing technology of rings: According to different raw materials or blank forms, the processing of bearing inner rings and outer rings is also different. Among them, the process before turning can be divided into the following three types. The whole processing process is: bar or tube (some bars need forging, annealing and normalizing)-turning-heat treatment-grinding.
2. Steel ball processing, steel ball processing also varies with the state of raw materials. Among them, the process before chipping or polishing can be divided into the following three types, and the process before heat treatment can be divided into the following two types. The whole processing process is: cold stamping of bars or wires (some bars need to be punched and annealed after cold stamping)-chipping, rough grinding, soft grinding or polishing.
3. Processing technology of roller The processing of roller is different according to different raw materials, and the process before heat treatment can be divided into the following two types. The whole processing process is as follows: lathing bar or cold heading wire, soft grinding of endless belt string-heat treatment-soft spot string-rough grinding of outer diameter-rough grinding of end face-final grinding of end face-fine grinding.
4. Processing technology of the cage The processing technology of the cage can be divided into the following two categories according to the different design structures and raw materials:
(1) plate → cutting → punching → punching → shaping and finishing → pickling or shot blasting or stringing → final inspection → rust prevention → packaging → storage (to be assembled and assembled).
(2) Processing technology of solid cage: The processing of solid cage varies according to different raw materials or hairiness. Before turning, it can be divided into the following four blank types. The whole processing process is: bar, pipe, forging, casting-turning inner diameter, outer diameter, end face, chamfering-drilling (or broaching and boring)-. Second, the assembly process of rolling SKF bearing:
Rolling bearing parts, such as inner ring, outer ring, roller and cage, etc. After passing the inspection, enter the assembly workshop for assembly. The process is as follows:
Demagnetization cleaning of parts → grouping selection of internal and external rolling groove dimensions → assembly → checking clearance → riveting cage → final inspection → demagnetization cleaning → rust prevention and packaging → entering finished product warehouse (packaging and delivery).
