Raw materials - inner and outer ring processing, steel ball or roller processing, cage (punching or solid) processing - bearing assembly - bearing finished products.
▶In the bearing production process, the most critical are the following:
1 Forging
The forge link is an important link to ensure the reliability and life of the bearing. After the raw material is forged, the bearing ring blank is formed. At the same time, the organizational structure of the raw materials becomes more compact and the flow linearity becomes better, so that the bearing reliability and service life can be improved. In addition, the forging process will directly affect the utilization of raw materials, which will have an impact on production costs.
2 heat treatment
The heat treatment process involves high temperature treatment of the bearing rings after forging and machining, which directly affects the uniformity of carburizing in the bearing rings, improves the wear resistance and hardness of the bearings, and also affects the reliability and life of the bearings. The important link.
3 grinding process
After the heat treatment, the bearing ring needs to be milled, which is an important link to ensure the bearing accuracy. After grinding, the bearing ring production process is basically completed.
▶Inner and outer ring bearing process: bar - forging - car processing - heat treatment - grinding - super finishing - final inspection of parts - rust storage.
The main production equipment includes: cold heading machines, automatic ball bearings internal grinding machines, quenching lines, annealing furnaces, presses, CNC lathes, bearing grinding machines, internal groove grinding machines, external groove grinding machines, high-precision horizontal axis circular table surface grinding machines, CNC Milling machines, centerless grinding machines, high-precision grinding and grinding centerless grinding machines, precision channel superfinishing machines, CNC surface grinding machines, CNC reciprocating double-end surface grinding machines, high-temperature high-speed bearing testing machines, heat treatment production lines, and quality inspection equipment.
▶The basic production process of rolling bearings
Due to the different types of rolling bearings, structural types, tolerance classes, technical requirements, materials, and batch quantities, the basic production process is not exactly the same.
