Due to the different types, structural types, tolerance levels, technical requirements, materials and batch sizes of rolling bearings, their basic production processes are not exactly the same. 1. Processing process of main parts of various bearings: 1. The processing process of the ferrule: The processing of the inner and outer rings of the bearing varies depending on the raw material or blank form. The processes before turning can be divided into the following three types. The entire processing process is: Bar or pipe material (Some bars need to be forged, annealed, and normalized) ---- Turning ---- Heat treatment ---- Grinding ---- Grinding or polishing ---- Final inspection of parts ---- Anti-rust----warehouse----(to be assembled together) 2. The processing process of steel balls. The processing of steel balls also varies depending on the state of the raw materials. Among them, the process before crushing or polishing the balls, It can be divided into the following three types. The process before heat treatment can be divided into the following two types. The entire processing process is: Bar or wire cold punching (some bars need to be punched and annealed after cold punching) - ---Frustration, rough grinding, soft grinding or light ball----heat treatment----hard grinding----fine grinding----fine grinding or grinding----final inspection grouping----prevention Rust, packaging ---- put into storage (to be assembled) 3. The processing of rollers varies depending on the raw materials. The process before heat treatment can be divided into the following two types. The process is: bar turning or wire cold heading, then ring belt stringing and soft grinding - heat treatment - soft spot stringing - rough grinding of outer diameter - rough grinding of end face - final grinding End face ---- fine grinding outer diameter ---- final grinding outer diameter ---- final inspection grouping ---- rust prevention, packaging ---- storage (to be assembled in a set). 4. Processing of cage The processing process of the process cage can be divided into the following two categories depending on the design structure and raw materials: (1) Sheet → shearing → blanking → stamping → shaping and finishing → pickling or shot peening or string polishing → Final inspection → Rust prevention, packaging → Warehousing (to be assembled in a set) (2) Processing process of the physical cage: The processing of the physical cage varies depending on the raw materials or roughness. Among them, it can be separated before turning It is the following four types of blanks, and the entire processing process is: bar stock, pipe stock, forgings, castings - inner diameter, outer diameter, end face, chamfering - drilling (or drawing, boring) ----Pickling----Final inspection----rust prevention, packaging----warehousing . 2. Assembly process of rolling bearings: rolling bearing parts such as inner ring, outer ring and rolling elements. and cages, etc., after passing the inspection, enter the assembly workshop for assembly. The process is as follows: parts demagnetization and cleaning → inner and outer rolling (groove) channel size group selection → fitting → check clearance → riveting cage → Final inspection→demagnetization, cleaning→rust prevention, packaging→entering into finished product warehouse (packing, shipping).
