Abrasive abrasive is made the main raw material

Diamond abrasive is diamond as abrasive, metal powder, resin powder, ceramics, and metal plating into various shapes as binder and abrasive grinding tools. Synthetic diamond abrasive used in the  grinding wheel manufacture processing of high normal abrasive machining hard hard metal and non-metallic brittle materials: such as cemented carbide, optical glass, ceramics, stone, semiconductor materials, etc., with high efficiency grinding, good processing quality, durable durable. High hardness of the diamond abrasive, grinding performance and other characteristics are more expensive, so the structure and characteristics of the general mill having very different. Its technical parameters, including the abrasive particle size, binders, concentration, etc. four elements. Each abrasive has its abrasive paper sheet  intrinsic properties, the correct selection and use, can only be assured grinding efficiency and processing quality. China Stone Network
An abrasive
Abrasive abrasive is made the main raw material, directly from the grinding action of the workpiece. Superhard abrasive abrasives are used in two main categories:
Synthetic diamond and cubic boron nitride.
① synthetic diamond is the hardest material, according to its crystal shape and strength, into a variety of models. It is  flap wheel suitable for a variety of hard and brittle materials grinding.
② CBN is yet another hardness only to diamond superabrasive. But its thermal stability and chemical inertness of an iron group metal than diamond. It is suitable for hard toughness (black metal) material grinding.
