Description:
Diamond sanding abrasive belt is a kind of coated abrasive tool, which is superhard material (synthetic diamond) abrasive particles adhesive to the flexible base by bond.And can be divided into metal nickel plating electroplated bond and resin bond, resin bond also consists flexible and hard type. In some sense The grinding by diamond sanding belt for thermal spray coating industry can replace that of diamond grinding wheel and film polishing. Diamond sanding belt can complete the grinding and polishing process. Recently, it is widely used in thermal spray coating industry, the production and repair of hydraulic cylinder and turbine blade.
Application:
Diamond sanding abrasive belt can be widely used for grinding steel, stone, glass, ceramics, mono crystalline silicon, polysilicon, zirconia, alumina, metal-nonmetallic synthetic materials, cemented carbide, aluminum magnesium alloy, aluminum beryllium alloy, titanium alloy and etc. hard brittle materials.
