The basic knowledge of diamond grinding wheelDiamond abrasive as raw material, respectively, with metal powder, resin powder, ceramic and electroplating metal as a binding agent, made of a circular hole in the center of the consolidated diamond grinding wheel known as.Their subjectsMechanical Engineering (a subject);Abrasives (two subjects);Grinding wheel (three subjects)structureDiamond wheel structure generally by the working layer, matrix, the transition layer of three parts.Working layer, also known as diamond layer, by the abrasive, binder and filler composition, is the working part of the wheel. Transition layer, also known as non-diamond layer, by the binder, metal powder and filler composition, the diamond layer is firmly connected to the substrate on the part.A base for receiving the abrasive layer, and, in use, firmly retained by the flange on the spindle of the grinding machine. General metal bonding agent products selected steel, alloy steel powder for the matrix; resin bonding agent used aluminum, bakelite as the matrix. From aluminum, steel or bakelite processing, starting from the support layer and the role of loading card abrasive. The quality of grinding wheel quality and use of high and low accuracy and the matrix has a great relationship.characteristicDiamond grinding wheel characteristics include the type of diamond abrasive, particle size, concentration, binder and shape and size.useAs the characteristics of diamond abrasives (high hardness, high compressive strength, good wear resistance), so that the grinding wheel in the grinding of hard and brittle materials and hard to become an ideal tool, not only high efficiency, accuracy High, and good roughness, abrasive consumption, long service life, but also improve the working conditions. Therefore, it is widely used in hard and brittle materials with low iron content, such as hard alloy, high alumina porcelain, optical glass, agate gemstone, semiconducting material and stone.classificationDiamond grinding wheel according to the binder can be divided into: resin-bonded diamond wheel; ceramic bond diamond wheel; metal bond diamond wheel (bronze bonded diamond wheel)Diamond grinding wheel can be divided according to the production process: sintered diamond grinding wheel (resin bonded diamond wheel; ceramic bonded diamond wheel; metal bonded diamond wheel); electroplated diamond grinding wheel; brazing diamond wheel.Diamond grinding wheel can be divided into: grinding diamond diamond wheel; grinding carbide grinding wheel with diamond (diamond knife grinding wheel); diamond grinding wheel with diamond grinding wheel; coreless grinding machine with heartless diamond grinding wheel; grinding ceramic products With diamond grinding wheel; cutting with diamond grinding wheel (also known as diamond cutting disc); diamond saw blade. Diamond wheel according to the appearance or shape can be divided into: parallel grinding wheel; cylindrical grinding wheel; cup-shaped grinding wheel; bowl-shaped wheel; dish wheel; edging grinding wheel;Diamond grinding wheel is used for abrasive machining of hard and brittle materials such as glass, ceramics, ferrite and semiconducting materials, grinding of metal materials, machining of carbide materials, grinding of electrolytic grinding and grinding of diamond bits in grinding centers Heavy cutting, with a good wear resistance, high efficiency, long service life characteristics
