The circular bonded abrasive tools with a through hole in the center are made of diamond abrasives as raw materials and metal powder, resin powder, ceramics and electroplated metal as binders respectively, which are called diamond grinding wheels.


The diamond grinding wheel structure generally consists of three parts: working layer, matrix and transition layer. The working layer, also called the diamond layer, is composed of abrasives, binders and fillers and is the working part of the grinding wheel. The transition layer, also known as the non-diamond layer, is composed of binder, metal powder and filler. It is the part that firmly connects the diamond layer to the substrate. The base body is used to receive the abrasive layer and is firmly clamped on the grinder spindle with a flange when in use. Generally, metal bond products use steel and alloy steel powder as the matrix; resin bonding products use aluminum alloy and bakelite as the matrix. Processed from aluminum, steel or bakelite, it plays the role of supporting the working layer and mounting the grinding tool. The quality of the grinding wheel and the accuracy of its use are closely related to the matrix.


The characteristics of diamond grinding wheels include the type, particle size, concentration, bonding agent and shape and size of diamond abrasives.


Due to the characteristics of diamond abrasives (high hardness, high compressive strength, and good wear resistance), diamond abrasives have become ideal tools for grinding hard and brittle materials and cemented carbide in grinding processes. They not only have high efficiency and precision High, good roughness, less abrasive tool consumption, long service life, and can also improve working conditions. Therefore, it is widely used in metals and non-metallic hard and brittle materials with low iron content that are difficult to process with ordinary abrasive tools, such as cemented carbide, high alumina porcelain, optical glass, agate gemstones, semiconductor materials, stones, etc.


Diamond grinding wheels can be divided into: resin bond diamond grinding wheels; ceramic bond diamond grinding wheels; metal bond diamond grinding wheels (bronze bond diamond grinding wheels). Diamond grinding wheels can be divided into: sintered diamond grinding wheels (resin bond diamond grinding wheels) according to the production process. Diamond grinding wheel; ceramic bond diamond grinding wheel; metal bond diamond grinding wheel); electroplated diamond grinding wheel; brazed diamond grinding wheel. According to the grinding method, diamond grinding wheels can be divided into: diamond grinding wheels for grinding diamonds; diamond grinding wheels for grinding carbide (diamond knife grinding wheels); diamond grinding wheels for grinding diamond composite sheets; centerless grinding diamond grinding wheels for coreless grinders; and grinding ceramic products. Use diamond grinding wheels; diamond grinding wheels for cutting (also known as diamond cutting blades); diamond saw blades. According to appearance or shape, diamond grinding wheels can be divided into: parallel grinding wheels; cylindrical grinding wheels; cup-shaped grinding wheels; bowl-shaped grinding wheels; dish-shaped grinding wheels; edge grinding wheels; grinding discs, etc.


Diamond grinding wheels are used for the grinding of hard and brittle materials and metal materials such as glass, ceramics, ferrite, and semiconductor materials, the shape processing of cemented carbide materials, electrolytic grinding, and the grinding of diamond drills used in grinding machining centers, etc. Heavy-duty cutting, with the characteristics of good grinding wear resistance, high efficiency and long service life.
