Generally speaking, the diamond grinding wheel can mainly be divided into three types, the first type is ordinary grinding materials and grinding tools, including adamantine spar series, silicon carbide, resin grinding tools, ceramics grinding tools and so on. The secondly type is coated abrasive, including gauze, abrasive paper and abrasive belt. The third type would be the super hard materials, including diamond grinding wheel, Cubic Boron Nitride and its related products. Cutting and grinding ways are the ones which can not be replaced among machine work, on the contrary, they would be developed more and more mature.

In the new century, cutting and grinding machining is also the third popular machine work all over the world, nowadays the hard turning is gradually replaced by some grinding ways, however, because of the development and using of cementation technology and top grade grinding materials, the diamond grinding wheel still plays the important role in machine work.

According to the grinding material and grinding tools products and market report from the U.S.A, in last year, the total quantity demanded of grinding material and grinding tools in the U.S.A reaches up to 5.8 billion USD and what’s more it will increase by 4 percent every year.
