Mixed reaction produced by high elasticity and high strength rubber material with a very sharp aluminum oxide, silicon carbide. Relatively 10S series 9R series of polishing abrasive hardness abrasive polishing hard grinding power, high grinding efficiency and long life characteristics. Its polishing weaker than the 10S series polishing abrasive teach hard,DC wheel, therefore, it has the grinding power, high grinding efficiency and long life characteristics. Polishing abrasive polishing weaker than 10S series.abrasive wheel

Typical glass edge processing: diamond rough grinding wheel - Diamond Diamond fine grinding wheel - 9R series of polishing abrasive.
