There's a lot of trouble with the production process. We have a lot of rings and other accessories here. And the assembly. The so-called assembly, that is, the acquisition of rings and various accessories. Assemble the finished bearings and sell them.I think the process should be like this. Start with the ringRing: cutting plane and centerless grinding - zetoms hole chamfering -- dredging completed after heat treatment are then sent to the bearing factory.Bearing factory: automatic ring grinding (131201143 model) - ultra fine - cleaning ring - Union - pressure cage - cleaning product bearings - plus grease - gland - rust proof oil - Packaging - delivery
To know the production process, we should first make sure that the micro bearings or large and medium-sized bearings. According to your procedure, should belong to the small class.Ferrule factory:1., blanking (points bar material, pipe material, separate type)2. plane grinding and centerless grinding3., zetoms chamfer hole, dustproof groove4. heat treatment, tempering (some passivation treatment)The above procedure must be checked for size, deformation and allowance.Finish machining:1. plane mill (end dimension, parallel difference)2. centerless grinding (size, roundness, ultra precision, roundness)3. automatic grinding (131 size, roundness, roughness). 143 size, roundness, roughness. 201 aperture, taper)4. ultra fine (roundness, roughness, finish)In fact, there are still some processes
The first step is forging forming, annealing, and machining, heat treatment and, to 58-62 degree, then the rough grinding, fine grinding or tempering stability, ultra precision grinding, reach the oil standard, then the rolling body and the inner and outer ring, a retainer, antirust oil - Packaging - hair the goods. Indicate that GCR15 or GCR15SIMN material is selected according to the thickness of the bearing
