For Finishing Various Holes / Super Sizing Reamer
Longer Tool Life for Hardened Steel Parts such as Gears This CBN electro-deposited wheel has a long service life in the process of hardened steel components such as gears by improving form-stability. ・The number of workpieces that can be machined can be increased while maintaining shape accuracy by making the abrasive grains tougher and stabilizing the amount of grain protrusion. (longer wheel life) ■Features
A high performance superabrasive reamer capable of finishing holes precisely by 1 pass. Highly Precise Hole Finishing by 1 Pass
・Capable of 1 pass hole machining. ・High accuracy (roughness • roundness • cylindricity). ・Reduction of rolled edge around lubricant hole or keyway. ・Skill is not required. ■Features

Cam Grinding Wheel / VITMATE HIG Wheel
・This wheel has excellent cutting ability and dressing performance as well as high wear resistance to work best in grinding operations that require high accuracy. ・This bond has higher wear resistance to make this wheel ideal for grinding that requires high grinding accuracy. ■Features ・Grinding of Cams, Crankshafts, Injection needles, Rocker arms, Turbo components, etc. ■Applications Highly Efficient Wheel for Processing with High Dressing Performance and Wear Resistance The employment of the bond that has high grain holding force enables the properties of CBN grains to be utilized fully to achieve highly efficient grinding and significant tooling cost reduction.
For Rubber Belts / PSL Wheel
It has high abrasive grain holding power, together with large abrasive grain protrusion amount and abrasive grain spacing, providing excellent sharpness and discharge performance of chips. ・Ideal for machining that tends to cause loading due to deposition of chips such as rubber and resin. ■Features Ideal for Materials that Tend to Cause Loading such as Rubber and Resin
・Machining of various automotive rubber belts ■Applications
