Due to the type, structure type, tolerance class, technical requirements, materials and batches of rolling FAG bearings, the basic production process is not identical.
First, the processing of the main parts of various FAG bearings:
1. The processing of the ferrule: the processing of the inner and outer rings of the FAG bearing varies according to the raw material or the blank form. The process before the machining can be divided into the following three types: the whole processing process is: bar or tube Materials (some bar materials need to be forged and annealed, normalized)----Car processing----heat treatment----grinding----finishing or polishing----final inspection of parts--- -Anti-rust----Warehouse----(to be equipped with a package)
2. The processing of steel balls and the processing of steel balls are also different depending on the state of the raw materials. The processes before the frustration or the photosphere can be divided into the following three types. The processes before the heat treatment can be further divided into the following steps. Two kinds, the whole processing process is: bar material or wire cold punching (some bars need to be punched and annealed after cold pressing)----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 during the processing of the roller varies according to the raw materials. 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, string ring and soft grinding ----Heat treatment----string soft point----grinding outer diameter----grinding end face----finishing end face----fine grinding outer diameter----finishing outer diameter ---- Final inspection group----rust prevention, packaging----into the warehouse (to be combined with the package).
4. The processing process of the cage of the cage can be divided into the following two categories according to the design structure and raw materials:
(1) Sheet → shear → punching → stamping forming → shaping and finishing → pickling or shot peening or stringing → final inspection → rust prevention, packaging → storage (to be combined)
(2) The processing process of the solid cage: the processing of the solid cage varies according to the raw materials or the gross damage. The following four types of blanks can be divided into the following processing: the bar is Pipe, forgings, castings----car inner diameter, outer diameter, end face, chamfering----drilling (or pulling holes, boring)----pickling----final inspection---- Anti-rust, packaging----into the warehouse.
