Bearing component processing

1. Processing of the ferrule (inner ring and outer ring): 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 process before the machining can be divided into the following three types. The processing process is: bar material or pipe material (some bars need to be forged and annealed, normalized)----car processing----heat treatment----grinding----finishing or polishing-- -- Final inspection of parts --- rust prevention --- storage --- (to be combined with the package)

2, the processing of steel balls: the processing of steel balls also varies according to the state of the raw materials, in which the process before the frustration or the light ball can be divided into the following three, the process before the heat treatment, and can be divided into The following two processes, the whole process is: bar or wire cold-punching (some bars need to be punched and annealed after cold-shrinking)----frustration, rough grinding, soft grinding or light ball---- Heat treatment----hard grinding----fine grinding----finishing or grinding----final inspection group----rust prevention, packaging----into the warehouse <to be combined with the package>.

3, the processing of the roller: the processing of the roller varies according to the raw materials, wherein the process before the heat treatment can be divided into the following two, the whole processing process is: bar processing or wire cold rolling after the string Belt and soft grinding----heat treatment----string soft point----rough grinding outer diameter----grinding end surface----finishing end surface----fine grinding outer diameter----finish Grinding outer diameter----final inspection group----anti-rust, packaging----into the warehouse (to be combined with the package).
