The cutting disc is the most important type of grinding tool in grinding. The high quality cutting disc supplier is a porous body which is prepared by adding a binder to an abrasive, compacting, drying and baking. Due to the different abrasives, binders and manufacturing processes, the characteristics of the cutting discs vary widely, which has a significant impact on the quality, productivity and economy of the grinding. The characteristics of the cutting disc are mainly determined by factors such as abrasive, particle size, binder, hardness, structure, shape, and size. According to the abrasive used, it can be divided into ordinary abrasive (corundum and silicon carbide) grinding wheel and natural abrasive super-hard abrasive and (diamond and cubic wheel boron nitride, etc.) grinding wheel; According to the shape, it can be divided into a flat grinding wheel, a beveling grinding wheel, a cylindrical grinding wheel, a cup-shaped grinding wheel, a dish-shaped grinding wheel, etc.; according to the bonding agent, it can be divided into a ceramic grinding wheel, a resin grinding wheel, a rubber grinding wheel, a metal grinding wheel and the like. The characteristic parameters of the grinding wheel mainly include abrasive, viscosity, hardness, bonding agent, shape and size.
