Knowledge of bearing roller processing explanation - bearing

1. The craft course of cylindrical roller bearing blank forming - burring or band - soft grinding the raceway surface - soft grinding double - thermal solution to coarse grinding roller surface before, coarse grinding the double - coarse grinding roller surface after - eventually double end face grinding to fine, end mill rolling surface, super finishing rolling surface to clean, dry, final inspection group - oil packing appearance, size. 2. The technology course of tapered roller bearing blank forming - burring or band - soft grinding the raceway surface - soft grinding double - thermal solution to coarse grinding roller surface, fine grinding and rolling surface grinding ball base to end mill rolling surface, super finishing rolling surface to clean, dry, final inspection group - oil packing appearance, size. The above two kinds of roller crown shape bus bar rolling surface can make it, if the convex metric is less than 0. 005 mm, the individual can be indirectly in super finishing rolling surface process; If a convex metric is greater than zero. 005 mm, the individual can be in the last final rolling surface process grinding out the crown, then superfinishing. 3. The craft course of needle roller blank forming to deburring, thermal solution to thick, thin, end mill rolling surface, super finishing rolling surface polishing or sawdust. On flat and cone head needle, such as blank shape is difficult to guarantee the length size tolerance, can add double end face grinding process in the rolling mill. If need to crown shape bus bar rolling surface, can indirectly in super finishing rolling surface or channeling light process. 4. The craft course of asymmetric spherical roller type blank forming - burring or band - soft grinding the raceway surface - soft grinding double - hot solve to the ball end face grinding, grinding ball end to thick, thin, end mill rolling surface, polishing to clean, dry, final inspection group - oil packing appearance, size. Symmetrical spherical roller technological process is: the blank shape - burring or band - soft grinding the raceway surface - soft grinding double - thermal solution to coarse grinding roller surface, thick, double end face grinding to fine, end mill rolling surface, polishing to clean, dry, final inspection group - oil packing appearance, size. If the rolling surface grinding process can reach request appearance coarse degree, not for polishing.
