Abrasives manufacturing process are

assign material, mixing, forming, heat treatment, machining and inspection. With different binders, manufacturing processes are not the same. Mainly vitrified bond-pressure method, the abrasive and binding agent according to the weight ratio of formulation weighed, placed in the standard abrasives  mixer are mixed evenly into a metal mold in the press forming of rough grinding. Blank firing kiln dried and then into the firing temperature is generally about 1300 ℃. When the binding agent is low melting point welded shut, the firing temperature is lower than 1000 ℃. Then the provisions of size and shape precision machining, final inspection products.
Resin bonded abrasives are generally at room temperature in the press forming, there is also the condition of heating under sandpaper  pressurized hot pressing process with heating. After forming in the hardening furnace hardening. Phenolic resin as binding agent, the curing temperature is 180 ~ 200 ℃.
Rubber bonded abrasives mainly used for mixing roller machine and rolled into thin slices, then die cutter punching molding; also some with loose material, the inner mold into the press molding. After the vulcanization molding vulcanization tank, a temperature of 165 ~ 180 ℃.
Metal bonded abrasives manufacturing process has wide belt  two kinds of powder metallurgy and electroplating method, mainly for superabrasive abrasive. Bronze powder metallurgy method as the binding agent used after mixing at room temperature or under hot pressure molding, and sintering process. Plating with nickel or nickel-cobalt alloy as the metal plating, the plating process according to the abrasive bonded to a substrate, made of abrasive.
