Due to the different types, structure type, tolerance level, technical requirements, and bulk materials such as rolling bearings, the basic production process is not the same.
A variety of bearing the main parts of the process:
1. Rings process: bearing inner and outer rings by processing raw materials or blank forms differ, wherein the step car before processing can be divided into the following three, the whole process are: bar or tube material (subject to some bar forging and annealing, normalizing) ---- ---- car processing heat treatment ---- grinding ---- lapping or polishing parts censoring ---- ---- storage rust ---- ---- (to be fit suit with>
2. Ball's process, according to the state of the same ball processing of raw materials differ, wherein the step before the ball fell cut or light can be divided into the following three, before the heat treatment process can be divided into the following two kinds, the whole process are: bar or wire cold punch (need to punch some belts and annealing after cold-bar) ---- setback cut, coarse grinding, Polishing or light ball ---- Heat Treatment - --- ---- grinding hard grinding or polishing lapping ---- ---- ---- rust final inspection grouping, packaging, warehousing ---- <to be fit suit with>.
3. Roller roller processing process depending on the raw materials vary, wherein the step before the heat treatment can be divided into the following two, the whole process are: bar car after processing or cold heading wire string annulus and Polishing heat treatment ---- ---- ---- point string soft kibble kibble end face of the outer diameter ---- ---- ---- end face grinding finely grinding the outer diameter of the outer diameter of the end ---- ---- group ---- rust final inspection, packaging, warehousing ---- (to be fit suit with>.
4. Cage to keep the process according to the process frame structure different designs and materials can be divided into the following categories:
(1) sheet metal cutting → → → stamping → blanking shaping and finishing → pickling or shot blasting or string light rust → → final inspection, packaging → storage (to be combined with a suit)
(2) processing entity holding cage: solid cage frame processing, raw materials or by bad hair differ, of which the first vehicle processing can be divided into the following four types of blank, the whole process are: bar, tubing, forging, casting ---- car diameter, outside diameter, face, chamfer ---- drilling (or broaching, boring) pickling ---- ---- ---- final inspection rust, packaging, warehousing ---- <to be fit suit with>.
