the main material grinding wheel

Grinding wheel is used for grinding abrasive, thin wheel dry pads  a call. Grinding wheel as the dental industry, many industrial enterprises were adopted, then the grinding wheel which specific material it?
The so-called material is produced using abrasive grinding wheel. The most commonly used abrasive grinding wheel is corundum (A) and corundum (WA), followed by black silicon carbide (C) and green silicon carbide (GC), the remaining common and chrome corundum (PA), monocrystalline corundum ( SA), microcrystalline corundum (MA), zirconium corundum (ZA). Produced using different abrasive grinding wheel, there are different characteristics.
Corundum grinding wheel: slightly higher than the diamond cup wheels  hardness of corundum corundum, corundum toughness lower than in grinding, abrasive shatter easily, so grinding heat a small, suitable for manufacturing grinding hardened steel, high carbon steel , high-speed steel and thin-walled parts with grinding wheel, high cost than corundum.
Corundum grinding wheel: corundum hardness, toughness, suitable for grinding high tensile strength metals such as carbon steel, alloy steel, malleable iron and hard bronze, etc. The  industrial saw blades abrasive grinding performance, adaptability , commonly used in the removal of coarse large margin, cheap, can be widely used.
Green silicon carbide grinding wheel: Green silicon carbide high hardness brittle than black, abrasive sharp, good thermal conductivity, suitable for grinding carbide, optical glass, ceramics and other brittle materials.
