1. The process of cylindrical roller
Blank forming, deburring or band-RuanMo groove surface-RuanMo double end, heat treatment and the coarse grinding surface rolling, before the coarse grinding end to double the coarse grinding surface after rolling and grinding end to end the double fine, end face and the rolling mill finish machining, clean, dry rolling surface appearance, size and final inspection group-with oil packing.
2. The technological process of the tapered roller
Blank forming, deburring or band-RuanMo groove surface-RuanMo double end, heat treatment, surface coarse grinding and fine grinding roll surface grinding ball rolling and the surface-end face and the rolling mill finish machining, clean, dry rolling surface appearance, size and final inspection group-with oil packing.
Above two kinds of roller can be made into convex degree form bus rolling face, if convex metric is less than 0.005 mm, generally can be directly in the super finishing rolling surface process; If the convex metric is greater than 0.005 mm, can generally be on the final end mill roll surface grinding process the protruding degree, and then to super finishing.
3. The technological process of the needle
Blank forming, deburring, heat treatment and thick, thin, end face-super finishing rolling mill roll surface or sawdust polishing.
To crew cut and cone head needle, such as blank forming are hard to guarantee length size tolerance, then can increase in grinding roll grinding double end process. If need to crown bus rolling face shape, which can be directly in the super finishing rolling surface or channeling process light.
4. The unsymmetrical spherical roller process
Blank forming, deburring or band-RuanMo groove surface-RuanMo double end face and the ball mill, heat treatment, surface grinding ball and thick, thin, end end rolling mill, polishing and surface cleaning, drying and final inspection and appearance, size packet with oil packing.
Symmetric type spherical roller process is:
Blank forming, deburring or band-RuanMo groove surface-RuanMo double end, heat treatment and coarse grinding roll surface coarse, and end face and fine grinding double end rolling mill, and polishing and surface cleaning, drying and final inspection and appearance, size packet with oil packing.
If the end mill roll surface process can reach the surface roughness requirements, the don't polishing.
