The structures of grinding wheel consist of three parts which conclude the work level, the substrate and the transitional layergenerally. The work level ,the grinding tool's effective range ,is also called the the diamond riddlings, which is made of the grinding compound, the cement and the padding . The transitional layer is also called as the non-diamond riddlings,which is made of the cement, the metal powder and the padding , connects reliably the diamond riddlings in the substrate.And at last,the substrate is by the aluminum, the steel or the bakelite ,which plays the role of supporting the work level and installs the card grinding . Because of the diamond grinding wheel's symobals ,such as high degree of hardness , compressive strength ,and resistance. The diamond grinding wheel is as an ideal tool in the abrasive machining , not only the efficiency is high, the precision is high, moreover roughness is good. The grinding tool consumes, the service life to be long few, meanwhile may improve the work conditions. Therefore widely uses in the low-valence iron content metal which and the nonmetallic hard crisp material the ordinary grinding tool difficulty with processes, like hard alloy, Gao Lvci, optical glass, agate gem, semiconducting material, stone material and so on.
