Bearing roller processing process

1 Technological process of cylindrical roller

blank forming deburring or ring belt soft grinding raceway surface soft grinding double end face heat treatment before rough grinding rolling surface rough grinding double end face after rough grinding rolling surface final grinding double end face fine, final grinding rolling surface superfinishing rolling surface cleaning, drying, final inspection appearance, size grouping and oiling packaging

2. Technological process of tapered roller

blank forming deburring or ring belt soft grinding raceway surface soft grinding double end face heat treatment rough grinding rolling surface fine grinding rolling surface grinding ball base surface final grinding rolling surface superfinishing rolling surface cleaning, drying, final inspection, appearance, size grouping, oiling and packaging

the above two kinds of rollers can be made into convex bus rolling surface. If the convex measure is less than 0.005mm, it can generally be directly carried out in the superfinishing rolling surface process; If the convexity measurement is greater than 0.005mm, press the OK key once at this time to grind out the convexity in the last final rolling surface grinding process, and then carry out superfinishing

3. The technological process of needle roller

blank forming and deburring hot automobile testing equipment intelligent processing rough, fine and final grinding rolling surface superfinishing rolling surface or sawdust polishing

for flat head and taper head needle rollers, if it is difficult to ensure the length and dimensional tolerance for blank forming, the double end face grinding process can be added during rolling. If the convex bus rolling surface is required, it can be directly carried out in the superfinishing rolling surface or light channeling process

4. Technological process of asymmetric spherical roller

blank forming deburring or ring belt soft grinding raceway surface soft grinding double end face heat treatment grinding non ball end face grinding ball end face coarse, fine, final grinding rolling surface polishing cleaning, drying, final inspection appearance, size grouping, oiling and packaging

the technological process of symmetrical spherical roller is:

blank forming deburring or ring belt soft grinding raceway surface soft grinding double end face heat treatment rough plastic processing machinery from the demand of the automotive industry increases the grinding rolling surface is coarse, the final grinding double end face is fine, the final grinding rolling surface is polished and cleaned, the final inspection appearance is dry, and the size group is oiled and packaged

if the final grinding process of rolling surface can meet the requirements of surface roughness, polishing may not be carried out. 5. Balancing machine (including field balancing instrument)
