Abrasives

Manufacturing process abrasive manufacturing process are: distribution of materials, mixing, forming, heat treatment, machining and inspection. With different binding agents, metal cut off wheels‍ manufacturing processes are not the same. ① mainly vitrified abrasive-pressure method, after the abrasive and binder in a weight ratio formula weighing, mixing placed inside the mixer, put into a metal mold in the press molding of abrasive blank (addition , there are a wet mixing method using a potting molding process). Dried and then into the blank firing kiln, the firing temperature is generally about 1300 ℃. Seizure when using low melting point binder, the firing temperature is lower than 1000 ℃. Then the provisions of size and shape precision machining, final inspection products. ② resin bonded abrasives are generally in the press molding at room temperature, there is also heating conditions in the lower side of pressurized heated hot pressing process. After forming the hardening furnace hardening. When the phenolic resin as binder, a curing temperature of 180 ~ 200 ℃. ③ rubber bonded abrasives mainly roller machine mixing and rolled into thin slices, then washed the knife punching molding; also some with loose material, into the inner metal mold press forming. After the vulcanization molding in the curing tank at a temperature Diamond cutting discs‍ of 165 ~ 180 ℃. ④ metal bonded abrasives manufacturing process, there are two powder metallurgy method and plating method, mainly for superabrasive abrasive. Bronze powder metallurgy as the binding agent used after mixing at room temperature or hot press molding, followed by sintering processing. Plating with nickel or nickel-cobalt alloy as the metal plating, according to the plating process in the consolidation abrasive substrate made ​​of abrasive.

Special varieties are sintered corundum abrasives and abrasive fibers and so on. Sintered corundum abrasive is alumina powder and mixing the right amount of chromium oxide, forming, sintering at 1800 ℃. This abrasive compact, have high strength, only its pore size is divided into two types of compact and porous type, for processing watches, instruments and other parts. Fiber containing abrasive or sticking with abrasive filaments (such as nylon) stone cutting wheels‍ as made ​​of raw materials, good elasticity, metal materials and products for polishing.
