1. The process of cylindrical roller
Blank forming, deburring or band - soft grinding raceway surface - soft grinding double face - heat treatment - former roughing ro lling surface, coarse grinding double face - after roughing rolling surface - end mill double face - fine, end mill rolling surface - super finishing rolling surface, cleaning, drying and final inspection appearance, size packet - oil packing.buy bearing
2. Tapered roller process
Blank forming, deburring or band - soft grinding raceway surface - soft grinding double face - heat treatment, coarse grinding rolling surface, fine grinding roller surface - ball base - end mill rolling surface - super finishing rolling surface, cleaning, drying and final inspection appearance, size packet - oil packing.china bearing supplier
The above two kind of roller can make it crowned form bus rolling surface, if the convex metric is less than 0.005 mm, generally can be directly in the super finishing rolling surface process; If the convex metric is gr eater than 0.005 mm, can generally be on the final end mill rolling surface process grinded convex degree, and then to superfinish.
3. Needle process
Blank forming, deburring, heat treatment, coarse and fine, end mill rolling surface - super finishing rolling surface or sawdust polishing.
To flush and cone head needle roller, such as blank forming are hard to guarantee length size tolerance, can in the mill rolling increase grinding double face process. If you want to crown shape bus rolling surface, can be directly in the super finishing rolling surface or channeling light in the process.bearing factory
4. Asymmetric spherical roller type of process
Blank forming, deburring or band - soft grinding raceway surface - soft grinding double face - heat treatment and grinding the ball end - ball end - coarse and fine, end mill rolling surface, polishing, cleaning, drying and final inspection appearance, size packet - oil packing.
Symmetrical type spherical roller process is:
Blank forming, deburring or band - soft grinding raceway surface - soft grinding double face - heat treatment, coarse grinding rolling surface, coarse, end mill double face - fine, end mill rolling surface, polishing, cleaning, drying and final inspection appearance, size packet - oil packing.engine bearings
If the end mill rolling surface process can achieve surface roughness requirement, then don t for polishing.
