Structure and classification of abrasive tools
1 the structure of the abrasive tool is generally composed of abrasive, binder, porosity, three elements. Abrasive is the main body of the abrasive tool, it is the basic factor of the cutting action of the abrasive tool, which is used to bond abrasive material, can make the abrasive tool has certain geometry and strength. The gap between the abrasive grains and the bond is called the air hole of the abrasive tool. According to the need of cutting process, the size, the number and the uniformity of the air hole can be improved, and the cutting performance of the abrasive tool can be improved. The so-called abrasive, that is, with different binders, the abrasive bond into a certain geometry or paste, for grinding, polishing, grinding and Jin Mo tool. '
2 the classification of abrasive tools due to the use of the tool is very extensive, because of the use of method, processing, processing requirements vary, so many types of abrasive. According to the use of different abrasives, abrasives are divided into two types of ordinary abrasive tools. The so-called ordinary abrasive tool is made of ordinary abrasives, such as corundum abrasive, silicon carbide abrasive and boron carbide abrasive. Ordinary abrasive abrasive in accordance with the form of the combination of abrasive abrasive, coated abrasives and grinding paste. According to the different ways to use bonded abrasives can be made of grinding wheel, oilstone, sand tile, grinding, polishing grinding block and so on; coated abrasives; made of sandpaper, emery cloth, abrasive belt. Grinding paste into plaster and ointment.
