Abrasives and abrasive products typically include two types of superhard abrasive materials

Abrasives and abrasive products typically include superhard abrasive materials into two categories . Ordinary ordinary abrasive grinding abrasive means made ​​of superhard abrasive material is abrasive diamond, cubic boron nitride and other superhard materials. Abrasive abrasive bound form by ordinary into bonded and coated abrasives , abrasive paste . In abrasive , a binding agent used in accordance with the different points abrasive fibre disc  vceramic abrasive, abrasive resins , rubber, abrasive, magnesite abrasives and other categories. In coated abrasives , the adhesive can be divided according to different categories . According to different grinding can be made ​​use of different basic shapes and characteristics , whereby can be divided into different categories , such as can be made of abrasive grinding wheels, grinding , stone, sand tiles , polishing block and so on. These different types of abrasive and have a different shape , the first shape and the type of abrasive grinding series combination of different binding agents into different varieties. Each species of different sizes and different characteristics constituting ceramic belt  the abrasive and combined into a variety of specifications .
 Bonded Abrasives manufacturing process are: distribution of material , mixing , forming, heat treatment, machining and inspection . With different binding agents , manufacturing processes are not the same. Vitrified abrasives used mainly -pressure method , the abrasive and binder weight ratio formula weighing, mixing evenly placed within the mixer, put in a metal mold in the press molding of abrasive rough . Blank firing kiln dried and then into the firing temperature is generally about 1300 ℃. When using a welded low-melting binder, the firing temperature is lower than 1000 ℃. Then the provisions of the exact size and shape processing, final inspection products. Resin bonded abrasives are generally molded in the press at room temperature , there is also pressurized with heating in a hot-pressing process under heating conditions . After forming in the hardening furnace hardening . The phenolic resin as binder, the curing temperature is 180 ~ 200 ℃. Rubber bonded abrasives used mainly for mixing roll machine and rolled into thin slices, then use a die cutter punching molding ; also some with loose material, into the inner metal mold press forming. After vulcanization molding vulcanization tank , a temperature of 165 ~ 180 ℃. Metal bonded abrasives manufacturing process , there are two powder metallurgy and plating method , mainly for superabrasive abrasive . Bronze powder metallurgy as the binding agent , or after mixing by hot abrasive fibre disc  press molding at room temperature , and then sintering processing. Plating with nickel or nickel-cobalt alloy as the metal plating , according to the abrasive bonded to a plating process on a substrate made ​​of abrasive.
Special varieties of sintered corundum abrasives and grinding with abrasive fibers and so on. Sintered corundum abrasive is alumina powder and the amount of chromium oxide mixing, forming , sintering at about 1800 ℃. This abrasive compact structure , high strength , mainly used for processing watches, instruments and other parts. Abrasive fibers are adhered or containing abrasive filaments ( eg nylon ) as the raw materials made of , its flexibility , materials and products used in metal polishing .
