The manufacturing process of the bonded abrasives includes: distribution, mixing, molding, heat treatment, processing, and inspection. The manufacturing process is different depending on the binder. The ceramic bond abrasive tool mainly adopts the pressing method, and the abrasive and the bonding agent are weighed according to the weight ratio of the formula, and then uniformly mixed in the mixing machine, put into the metal mold, and the abrasive blank is formed on the press. The blank is dried and then calcined in a kiln, and the firing temperature is generally about 1300 °C. When a low melting point fusion bonding agent is used, the firing temperature is lower than 1000 °C. Then accurately process according to the specified size and shape, and finally check the product. The resin bond abrasive is generally formed on a press at room temperature, and is also subjected to a hot press process which is heated while being heated under heating. After molding, it hardens in the hardening furnace. When the phenol resin is used as a binder, the curing temperature is 180 to 200 °C. The rubber bond abrasive tool is mainly mixed with a roller machine, rolled into a thin sheet, and then punched and formed by a punching knife; and some are loosely put into a metal mold and formed on a press. After molding, it is vulcanized in a vulcanization tank at a temperature of 165 to 180 °C.
The metal bond abrasives are manufactured by powder metallurgy and electroplating, and are mainly used for superabrasive bonded abrasives. The powder metallurgy method uses bronze or the like as a binder, and is mixed by hot pressing or at room temperature under pressure, and then sintered. The electroplating method uses nickel or nickel-cobalt alloy as the electroplating metal, and the abrasive is consolidated on the substrate by an electroplating process to prepare an abrasive article. Special varieties of grinding have sintered corundum abrasives and fiber abrasives. The sintered corundum abrasive is made by mixing and molding aluminum oxide powder and an appropriate amount of chromium oxide, and sintering at about 1800 °C. This kind of abrasive tool has a compact structure and high strength, and is mainly used for processing parts such as watches and meters. The fiber abrasive is made of fiber yarn (such as nylon wire) containing or adhering with abrasive. It has good elasticity and is mainly used for polishing metal materials and their products.
Super-hard abrasive bonded abrasives are mainly abrasive tools made of diamond, cubic boron nitride and the like. Due to the high price of diamond and cubic boron nitride and good wear resistance, the fixed abrasives made with them are different from ordinary abrasive bonded abrasives. In addition to the superabrasive layer, there are transition layers and substrates. The superabrasive layer is part of the cutting action and consists of a superabrasive and a binder. The substrate is supported by grinding and consists of materials such as metal, bakelite or ceramic. The transition layer is used to join the matrix and the superabrasive layer, consisting of a bonding agent, and sometimes it can be omitted. Commonly used binders are resins, metals, electroplated metals and ceramics.
