Manufacturer: Yamato Seitosyo Corporation
Model: Superfinish Stone

Feature

• Super Finish Stones are divided into two types: one is used by rotating the wheel and the other is used by vibrating the wheel.
• As the name suggests, super-finishing wheels are designed for final finishing, mirror-finishing, and precision polishing.
• This method of surface finishing is performed by pouring grinding fluid.
  

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
