The structure of the Diamond cup grinding wheel is different from the ordinary abrasive grinding wheel. Generally, it is composed of a diamond abrasive layer, a transition layer, and a matrix. The working layer, also known as the diamond layer, is composed of abrasives, bonding agents and fillers, and is the working part of the grinding wheel. The transition layer, also known as the non-diamond layer, is composed of a bonding agent, metal powder, and filler. It is the part that firmly connects the diamond layer to the substrate.

The base body is used to accept the abrasive layer and is firmly clamped on the main shaft of the grinder with a flange during use. Generally, metal bond products use steel and alloy steel powder as the matrix; resin bond selects aluminum alloy and bakelite as the matrix. It is made of aluminum, steel or bakelite, and plays the role of supporting the working layer and clamping abrasive tools. The molding quality of the grinding wheel and the accuracy of the users have a great relationship with the matrix.

Diamond grinding wheels are super-hard abrasive grinding wheels. Compared with ordinary abrasive grinding wheels, diamond grinding wheels have very obvious characteristics and advantages: the hardness of diamond abrasives determines the main characteristics of diamond grinding wheels, which can be difficult to process hard alloys, glass, ceramics, etc. The material is efficiently ground, and the grinding tool has the longest service life. Diamond has high abrasion resistance. The smaller the wear of the grinding wheel, the longer the use time. In the grinding process, the size, shape, and morphology of the diamond abrasive grains change little, which is more suitable for high-precision processing and has high production efficiency. , the Diamond grinding wheel is a tool that can meet high-efficiency and precision machining at the same time. The sharpened diamond grinding wheel can maintain the long-term micro-edge properties of the abrasive grains, and its good cutting performance ensures a small grinding force during the grinding process, thereby reducing the grinding power and saving energy. The thermal conductivity of diamond is very good, which is conducive to the evacuation of heat, avoids the phenomenon of burns, cracks, and lumps of the workpiece, and greatly improves the quality of the surface processing of the workpiece.
