1 cylindrical roller bearing technology course
Rough shape → deburring or zoning → Flexible Polishing raceway → Flexible Polishing the double face → thermal resolve → before kibble rolling surface after the kibbled rolling surface → kibbled double end face → → final → fine grinding double-end, end mill rolling surface → super finishing rolling surface → cleaning, boring final inspection of the appearance, size grouping → → oiled packaging.
Tapered roller bearings craft course
Rough shape → deburring or zoning → Flexible Polishing raceway → hot → Flexible Polishing double face solve → kibble rolling surface → finely ground rolling surface → → end mill grinding balls base surface the finishing rolling surface rolling surfaces → → washing boring → final inspection → oiled packaging appearance, size grouping.
Crown-shaped bus rolling surface above two rollers can be made, if less than convex metric 0.005mm, individual indirectly in the in super finishing rolling surface processes; if convex metric greater than 0.005mm, individual in the last final The the mill rolling surface process grind the crown, and then super finishing.
Needle craft course
→ coarse rough shape → the deburring → thermal resolve fine the end mill rolling surface → the super finishing rolling surface or sawdust polishing.
Flat head and cone needle, such as the rough shape is difficult to guarantee the length of the dimensional tolerances can add grinding mill scroll double-end process. The rolling surface of the crown-shaped busbar if required, can be an indirect process in the the super finishing rolling surface or channeling light.
Asymmetric spherical roller technology course
Rough shape → deburring belts the → soft tactics raceway → Flexible Polishing the double face → thermal resolve → mill non-ball end face the → → coarse grinding balls end face, fine, end mill rolling surface → polishing → cleaning, boring → final inspection of the appearance, size grouping → oiled packaging.
Symmetrical spherical roller technology course is:
Rough shape → go burrs or annulus → Flexible Polishing raceway solve → kibble rolling surface → rough → hot → Flexible Polishing double face, double face end mill → fine, end mill rolling surface → polishing → cleaning, boring → final inspection appearance size grouping → oiled packaging.
If a request can not be polished end grinding process of rolling surface to reach the appearance of rough.
