2022-06-02

(1) The production process of the inner and outer rings:

Unannealed bar→forging→retarding (normal) fire→turning→heat treatment (quenching-tempering)→grinding→finishing (ultra-finishing)→final inspection of parts→rust prevention→warehousing.

(2) The production process of steel balls:

Bar material (disk material) → upsetting ball blank → (removing ring belt) → smooth grinding (light ball) → heat treatment (quenching-tempering) → hard grinding → fine grinding → fine grinding (grinding) → final inspection group → cleaning, Anti-rust, packaging → storage.

(3) Roller production process:

Bar material (coil material) → upsetting (turning) → stripping → soft grinding → heat treatment (quenching-tempering) → hard grinding → stringing of soft points → fine grinding outer diameter → rough grinding end face → final grinding end face → fine grinding Outer diameter → final grinding outer diameter → (super-precision outer diameter) → final inspection grouping → rust prevention, packaging → storage.

(4) Production process of stamping cage:

Sheet material → shearing strip material → punching → stamping forming → shaping and finishing → pickling or shot peening or string light → final inspection → rust prevention, packaging → storage.

(5) Production process of solid cage:

Pipe material → car inner, outer diameter, end face → drilling (or pulling hole, boring) → deburring → pickling, final inspection → oiling, packaging → storage.
