Zhengzhou Research Institute For Abrasives & Grinding

Founded in 1958, our company is the unique comprehensive researching, developing and producing unit for the abrasive industry in China. It is the leader in superabrasive material and products field.

Diamond grinding wheel is used for processing work-pieces of hard carbide alloy, super-hard composite compact, PCD&PCBN, glass, ceramics, gem, ferrite and cast iron, spray coated articles, etc.

CBN grinding wheel is used for processing hard-to-work materials, such as high speed steel, alloy steel, die steel, bearing steel and tool steel, Titanium alloy, etc.

Grit size: 50/60~W0. 5
Outer Diameter: D8~D1065mm
Thickness: 1~200mm
Compare with normal abrasives

1. Longer life, is 30~200 times compare with the normal abrasives
2. High efficiency, can improve the productivity 50%~200% in different application
3. High precise, can improve the yield of the production
4. Cost effective, save a lot of cost of equipment, labor and time

Compare with domestic products:
1. Higher cbn concentration, longer life(150%, 175%, 200%)
2. Better capability of self sharp
3. Easy truing and degressing
