Applications of Superfinishing Stones
- ① The outer circumference of rollers incorporated into cylindrical roller bearings
- ② The sliding surfaces in contact with the rollers on the outer and inner rings of bearings
- ③ The outer circumference of engine camshafts
Purpose For Superfinish
- Improvement of surface roughness
- Improvement of wear and abrasion resistance
- Reducing frictional resistance
- Improvement of contact interval
- Removal of chatter marks and spiral marks
- Noise reduction in rotor and sliding area
- Load diffusing
- Improvement of electric and magnetic characteristic
- Improvement of adherability of plating, coating and vapor deposition
- Prevention of seal abrasion
- Improvement of quality level by mirror finish
