It can be used for rough grinding, semi-precision grinding and fine grinding, grooving and cutting of metal or non-metal workpieces with high speed rotation. The characteristics of grinding wheel are mainly determined by abrasive, particle size, binder, hardness, structure, shape and size.
Sandpaper wheel can be divided into resin grinding wheel, ceramic grinding wheel, diamond grinding wheel and so on according to the materials used; cutting slice can also be divided into resin cutting slice and diamond cutting slice.
