A cylindrical roller of the process
   
Rough shape → deburring or band → Flexible Polishing the raceway → soft grinding double end → heat treatment → coarse grinding rolling surface → coarse grinding double end → coarse grinding the rolling surfaces → final grinding double end → fine, and finally grinding the raceway → super finishing rolling surface → the cleaning, drying → final inspection the appearance, size grouping → ??oiled packaging.
   
Two tapered roller process
   
Rough shape → deburring or band → Flexible Polishing Flexible Polishing face → heat treatment → raceway → coarse grinding the rolling surfaces → finely ground raceway → ball base surfaces → final grinding the → the raceway → super finishing rolling surface cleaning, drying → final inspection of the appearance, size grouping → ??oiled packaging.
   
These two kinds of roller can be made convex-shaped bus rolling surface, convex metric is less than 0.005mm, generally in the rolling surface of the super finishing processes; convex metric is greater than 0.005mm, generally end in the last mill rolling surface processes grind convexity, then the super finishing.
   
3 process of the needle
   
 Deburring rough shape → → heat treatment → coarse, fine, and finally grinding the rolling surface → super finishing rolling surface or sawdust polishing.
   
Flat head and the needle of the cone, such as the rough shape is difficult to guarantee the length of the dimensional tolerances can increase grinding mill rolling double-end processes. If you need a rolling surface of the crown-shaped bus, directly on the rolling surface of the super finishing or in the channeling of light process.
  
(4) non-symmetrical spherical roller process
  
 Rough shape → go to glitches or band → Flexible Polishing raceway → Flexible Polishing face → heat treatment → mill grinding ball end of non-ball end → → coarse, fine, and finally grinding the rolling surfaces → polishing → ??washing, drying → appearance of the final inspection, the size grouping → oiled packaging.
   
Symmetrical spherical roller process is as follows:
   
Rough shape → deburring or band → Flexible Polishing the raceway → soft grinding double end → heat treatment → → coarse coarse grinding rolling surface, and finally grinding double end → thin, and finally grinding the rolling surface → polishing → ??washing, drying → final inspection appearance, size The grouped → oiled packaging.
   
If the final grinding process of the rolling surface can reach the surface roughness can not be polished.
