The main use of abrasives are cutting, grinding and polishing.Stone smooth light, can not leave the role of grinding tools.Therefore, the grinding equipment is a more important kind of stone machinery equipment.
Stone industry grinding equipment classification is relatively complex, generally according to its material distinction, can be divided into natural grinding tools and artificial grinding tools two categories.Common natural abrasives in the mechanical industry are only whetstone.According to the difference of shape and application, there are five kinds of grinding wheel, grinding head, whetstone, sand tile and coated abrasives.In addition, it is customary to classify abrasives as abrasives.

According to the different abrasives, the abrasives can be divided into abrasives and superhard abrasives.The former is made from abrasives such as corundum and silicon carbide, while the latter is made from superhard abrasives such as diamond and cubic boron nitride.
The consolidation grinding tool is a kind of grinding tool with a certain strength and a certain shape consolidated by the binder.It is usually composed of abrasives, binders and pores, and is called the three elements of a consolidated abrasive.
Generally, the factors of consolidation abrasive are: shape, abrasive size, particle size, hardness and binder.The method of measuring the hardness of abrasive tools is hand cone method, mechanical cone method, rockwell durometer method and sandblasting durometer method.
