Machining Process of Cylindrical Roller Bearings

In the process course of cylindrical roller bearings, remember to wear a mask and wash your hands regularly!

 

1. In the process course of Butterfly valves, remember to wear a mask and wash your hands regularly!

Blank forming → deburring or ring belt → soft grinding raceway surface → soft grinding double end surface → hot solution → before rough grinding rolling surface → rough grinding double end surface → after rough grinding rolling surface → final grinding double end surface → fine, final grinding rolling surface → super finishing rolling surface → cleaning, drying → final inspection appearance, size grouping → oiling and packaging.

 

 

2. Process history of tapered roller bearing

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

The above two kinds of rollers can be made into convexity shaped bus rolling surface, if the convexity is less than 0.005mm, individual can be carried out indirectly in the super finishing processing rolling surface process; if the convexity is greater than 0.005mm, individual can grind out the convexity in the final grinding rolling surface process, and then carry out super finishing processing.

 

3. The process history of rolling pin

Blank forming → deburring → thermal solution → coarse, fine, final grinding rolling surface → superfinishing rolling surface or sawdust polishing.

For flat head and tapered head rolling pin, such as blank forming difficult to guarantee the length of the size tolerance, can be in the grinding rolling add grinding double end face process. If you need convexity shaped bus rolling surface, can be indirectly in the super-finishing rolling surface or tampering light process.

 

4. The process of asymmetric spherical roller

Blank forming → deburring or ring belt → soft grinding raceway surface → soft grinding double end surface → hot solution → grinding non-ball end surface → grinding ball end surface → coarse, fine, final grinding rolling surface → polishing → cleaning, drying → final inspection appearance, size grouping → oiling and packaging.

The process course of symmetrical spherical roller is

Blank forming → deburring or ring belt → soft grinding roller surface → soft grinding double end surface → thermal solution → coarse grinding rolling surface → coarse, final grinding double end surface → fine, final grinding rolling surface → polishing → cleaning, drying → final inspection appearance, size grouping → oiling and packaging.

If the final grinding rolling surface process can reach the appearance of roughness requirements, it may not be polished.
