Bearing roller processing procedure

1. The processes of cylindrical roller blank forming - burring or band - soft grinding the raceway surface - soft grinding double - heat treatment - before the coarse grinding roller surface - coarse grinding double - after roughing rolling surface to eventually double end face grinding, fine, end mill rolling surface to super finishing rolling surface, cleaning, drying and final inspection group - oil packing appearance, size. 2. The technological process of the tapered roller blank forming - burring or band - soft grinding the raceway surface - soft grinding double - heat treatment - coarse grinding roller surface grinding balls - fine grinding roller surface - base - end mill rolling surface - super finishing rolling surface to clean, dry, final inspection group - oil packing appearance, size. Above two kinds of roller can make crown bus bar rolling surface, if the convex metric is less than 0. 005 mm, generally can be directly in the super finishing rolling surface process; If a convex metric is greater than zero. 005 mm, generally available in the last final rolling surface process grinding out the crown, then superfinishing. 3. Needle to deburring, heat-treatment process of billet to thick, thin, end mill rolling surface, super finishing rolling surface polishing or sawdust. For flat and cone head needle, such as blank shape is difficult to guarantee the length size tolerance, it can increase the double end face grinding in the mill rolling process. If you need crown shape bus bar rolling surface, can be directly in the super finishing rolling surface or channeling light process. 4. Asymmetric spherical roller type process of the blank shape - burring or band - soft grinding the raceway surface - soft grinding double - heat treatment and grinding of ball end to end face grinding balls, thick, thin, end mill rolling surface to polishing, cleaning, drying and final inspection group - oil packing appearance, size. Symmetrical spherical roller processes is: rough shape - burring or band - soft grinding the raceway surface - soft grinding double - heat treatment - coarse grinding roller surface - thick, double end face grinding to fine, end mill rolling surface, polishing, cleaning, drying and final inspection group - oil packing appearance, size. If the final rolling surface grinding process can reach surface roughness requirements, not for polishing.
