Bearing roller processing process

2020-05-19

1. Technological process of cylindrical roller

Blank forming → deburring or ring belt → soft grinding raceway surface → soft grinding double end surface → heat treatment → front rough grinding rolling surface → back rough grinding rolling surface → final grinding double end surface → fine, final grinding rolling surface → superfinishing rolling surface → cleaning and drying → final inspection appearance, size grouping → oil-coated packaging.

2. Process of tapered roller

Blank forming → deburring or ring belt → soft grinding raceway surface → soft grinding double end surface → heat treatment → rough grinding rolling surface → fine grinding rolling surface → grinding ball base surface → final grinding rolling surface → super finishing machining rolling surface → cleaning and drying → final inspection appearance, size grouping → oil-coated packaging.

The above two types of rollers can be made into a convex shape bus rolling surface. If the convex measurement is less than 0.005mm, it can be directly carried out in the process of super finishing the rolling surface.If the convex measurement is greater than 0.005mm, the convex degree can generally be grinded out in the last final grinding process of rolling surface, and then ultra-finishing can be carried out.

3. Needle rolling process

Blank forming → deburring → heat treatment → coarse, fine, final grinding rolling surface → super finishing machining rolling surface or sawdust polishing.

For flat head and cone head needle rolling, if the blank forming is difficult to ensure the length and dimension tolerance, it can be added in the grinding rolling grinding double end face process.If the convex shape of the bus rolling surface is needed, it can be directly processed in the process of super finishing rolling surface or channeling light.

4. Process of asymmetric spherical roller

Blank forming → deburring or ring belt → soft grinding raceway surface → soft grinding double end surface → heat treatment → grinding non-ball end surface → grinding ball end surface → coarse, fine, final grinding rolling surface → polishing → cleaning, drying → final inspection appearance, size grouping → oil-coated packaging.

The process of symmetrical spherical roller is as follows:

Blank forming → deburring or ring belt → soft grinding raceway surface → soft grinding double end surface → heat treatment → rough grinding rolling surface → thick, final grinding double end surface → fine, final grinding rolling surface → polishing → cleaning, drying → final inspection appearance, size grouping → oil-coated packaging.

If the final grinding rolling surface process can meet the surface roughness requirements, can not be polished
