The inner and outer rings of the bearing are ground. Bearing processing process:

1. Ring processing process: The processing of the inner and outer rings of the bearing varies depending on the raw material or blank form. The process before turning can be divided into the following The three types mentioned above, the whole processing process is: bar or pipe (some bars need to be forged, annealed and normalized)----turning----heat treatment----grinding----finishing Grinding or polishing----Final inspection of parts----Rust prevention----Storage----(to be assembled in a set).

2. The processing process of steel balls. The processing of steel balls also varies according to the state of the raw materials. The process before crushing or polishing the balls can be divided into the following three types. Before heat treatment The process can be divided into the following two types. The entire processing process is: Cold punching of bars or wires (some bars need to be punched and annealed after cold punching) - Frustrating, rough grinding, soft grinding Or photosphere ---- heat treatment ---- hard grinding ---- fine grinding ---- fine grinding or grinding ---- final inspection and grouping ---- rust prevention, packaging ---- storage < Ready to be assembled>.

3. The processing process of rollers The processing of rollers varies according to different raw materials. The process before heat treatment can be divided into the following two types. The entire processing process is: bar turning processing or After the wire rod is cold headed, the ring belt is stringed and soft ground - heat treatment - soft spot stringing - coarse grinding of the outer diameter - rough grinding of the end face - final grinding of the end face - fine grinding of the outer diameter Diameter----final grinding outer diameter----final inspection grouping----rust prevention, packaging----warehousing (to be assembled as a set).

4. Processing process of cage The processing process of the 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 blasting or string polishing → final inspection → rust prevention, packaging → storage (to be assembled)

(2) The processing process of the physical cage: The processing of the physical cage depends on the raw materials or raw materials. The roughness varies depending on the type. Before turning, the blanks can be divided into the following four types. 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----warehouse .
