1. Processing technology of the ferrule: The processing of the inner ring and the outer ring of the bearing varies according to the raw material or the form of the blank. The pre-processing process can be divided into the following three types. The whole processing process is: rod or pipe (some rods). Need forging, annealing and normalizing) - machining - heat treatment - grinding - fine grinding or polishing - final inspection of parts - rust prevention - storage (to be assembled and matched)
2. The processing technology of the steel balls and the processing of the steel balls are also different depending on the state of the raw materials. Among them, the process before grinding or polishing can be divided into the following three types: the process before heat treatment can also be divided into the following two types. The whole processing process is: cold punching of bars or wires (ring punching annealing is required for some bars after cold punching) - filing, rough grinding, soft grinding or light ball - heat treatment - hard grinding - fine grinding - fine grinding or grinding - Final inspection grouping - anti-rust, packaging - storage.
3. According to the different raw materials, the processing technology of the roll is also different. The process before heat treatment can be divided into the following two, the whole process is as follows: after turning bar or cold heading wire rod, string ring belt and soft grinding - heat treatment - string soft point - rough grinding outer diameter - rough grinding end face - final grinding end face - Fine grinding outer diameter - final grinding outer diameter - final grinding outer diameter - final inspection grouping - anti-rust, packaging - storage (to be assembled and matched).
4. According to the different design structures and raw materials, the processing technology of the cage can be divided into the following two categories:
(1) Sheet metal → cutting → punching → stamping forming → shaping, finishing → pickling or shot peening or wiring → final inspection → rust prevention, packaging → storage (to be assembled and matched)
(2) Processing technology of solid cage: The processing technology of solid cage is different due to the difference of raw materials or blank defects. Before machining, it can be divided into the following four kinds of rough machining. The whole machining process includes: bar, pipe, forging, casting - inner diameter, outer diameter, end face, chamfering - drilling (or broaching, boring) - acid Washing - final inspection - rust prevention, packaging - storage (to be assembled and matched).
