Resin wheel classification

December 7, 2018 by zengbin  

The choice of abrasive particle size is primarily related to machined surface roughness and productivity. When grinding requires coarse grinding, the grinding allowance is large, and the required surface roughness value is large, and coarser abrasive grains should be selected. Because the abrasive grains are coarse and the pores are large, the grinding depth can be large, and the grinding wheel is not easy to block and generate heat. When grinding requires fine grinding, the margin is small, the roughness value is required to be low, and finer abrasive grains can be selected. In general, the finer the abrasive grains, the better the surface roughness of the grinding. The resin grinding wheel is generally divided into an ordinary resin grinding wheel and a super-hard resin grinding wheel according to the abrasive. Ordinary resin grinding wheel is a grinding wheel with main abrasives such as white corundum, brown corundum, and silicon carbide as the main grinding component. The super-hard resin grinding wheel is a grinding wheel with a diamond or CBN as the main grinding component. Common flat cutting disc on sale and ordinary resin grinding discs are commonly used in the general resin grinding wheel market. Common diameters are 100, 180, 230, 300, 350, 400, 500. The super-hard resin grinding wheel market mainly includes super-hard resin cutting sheets and super-hard resin grinding discs. The diameter of common cutting sheets is 100, 125, 150, 200. Common disc sizes are 150, 200, 250, 300, 400.
