1. The processing of the ferrule: the processing of the inner ring and the outer ring of the bearing differs depending on the raw material or the blank method; the process before the machining can be divided into the following three types; the whole processing process is: bar or Pipe material (some bars need to be cast and annealed, normalized)----Car processing----heat treatment----grinding----finishing or polishing----final inspection of parts-- --Anti-rust----into the warehouse----(to be installed)
2. The processing of steel balls; the processing of steel balls is different depending on the condition of the raw materials; the process of frustration or pre-light ball; can be divided into the following three; the process before heat treatment; The following two processes; the whole processing 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 ---- fine grinding or grinding ---- final inspection group --- rust, packaging --- storage (to be installed).
3. Roller processing The processing of the roller varies depending on the raw material; the process before the heat treatment can be divided into the following two types; the whole processing process is: bar processing or wire cold rolling after the string And soft grinding----heat treatment----string soft point----rough grinding outer diameter----rough grinding end face----finishing end face----fine grinding outer diameter----final grinding Outer Diameter----Final Inspection Group----Anti-rust, packaging----into the warehouse (to be installed).
4. The processing progress of the cage process is different depending on the layout and raw materials; it can be divided into the following two categories:
(1) Sheet → shear → punching → stamping forming → shaping and finishing → pickling or shot peening or stringing → final inspection → rust prevention, packaging → storage (to be installed)
(2) Processing process of solid cage: processing of solid cage; different depending on raw materials or wool; in the process of machining, it can be divided into the following four blank types; the whole processing process is: Material, pipe material, forgings, castings----car inner diameter, outer diameter, end face, chamfering----drilling (or pulling holes, boring)----pickling----final inspection-- --Anti-rust, packaging----into the warehouse.
Second, the installation process of the rolling bearing:
Rolling bearing parts such as inner ring, outer ring, tumbling body and cage; after passing the inspection; enter the installation workshop for installation; the process is as follows:
Parts demagnetization, cleaning → internal and external rolling <ditch> road scale grouping → joint set → view clearance → riveting cage → final inspection → demagnetization, removal → rust prevention, packaging → into the product warehouse (boxing, shipping ).
