Diamond Grinding wheel

Using diamond abrasives as raw materials and using metal powder, resin powder, ceramics and electroplated metal as binders respectively, the circular bonded abrasive tools with a through hole in the center are called diamond grinding wheels (alloy grinding wheels) structure The structure of the diamond grinding wheel is different from that of ordinary abrasive grinding wheels. It is generally composed of a diamond abrasive layer, a transition layer and a matrix. 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. characteristic Diamond grinding wheels are super-hard abrasive grinding wheels. Compared with ordinary abrasive grinding wheels, they have very obvious characteristics and advantages: 1. The hardness of the diamond abrasive determines the main characteristics of the diamond grinding wheel. It can efficiently grind difficult-to-machine materials such as carbide, glass, and ceramics, and the grinding tool has the longest service life. 2. Diamond has high wear 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 particles change little, which is more suitable for high-precision processing and production. High efficiency, diamond grinding wheel is a tool that can meet both high efficiency and precision machining. 3. The sharpened diamond grinding wheel can maintain the micro-edge properties of the abrasive grains for a long time. The good cutting performance ensures a small grinding force during the grinding process, thus reducing the grinding power and saving energy. 4. The thermal conductivity of diamond is very good, which is conducive to the evacuation of heat, avoids burns, cracks and falling pieces of the workpiece, and greatly improves the quality of the surface processing of the workpiece. Classification According to the bond, 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) According to the production process, diamond grinding wheels can be divided into: sintered diamond grinding wheels (resin bonded diamond grinding wheels; ceramic bonded diamond grinding wheels; metal bonded diamond grinding wheels); electroplated diamond grinding wheels; brazed diamond grinding wheels. 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. Diamond grinding wheels can be divided according to appearance or shape: parallel grinding wheels; cylindrical grinding wheels; cup-shaped grinding wheels; bowl-shaped grinding wheels; dish-shaped grinding wheels; edge grinding wheels; grinding discs, etc. use Due to the characteristics and advantages of diamond abrasives, diamond grinding wheels have become the ideal tool of choice for grinding hard and brittle materials such as glass, ceramics, gems, stones, and cemented carbide. With the progress of the times, the development of science, the needs of society, the development of new materials, grinding processing continues to develop in the direction of high quality, high precision, high efficiency, and automation. The role of diamond grinding wheels is becoming more and more obvious, and metal bonding agents The diamond grinding wheel has high holding strength of abrasive grains, long life and less wear, so that the diamond grinding wheel can give full play to its characteristics of strong wear resistance and strong cutting ability in high-speed and ultra-high-speed, high-efficiency and high-precision grinding processes, especially in hard, brittle and difficult-to-machine processes. The material shows its obvious advantages and is widely used. Diamond grinding wheels are used in almost all industrial sectors and fields, such as aerospace, mold manufacturing, semiconductor manufacturing, optical processing manufacturing, etc. Ceramic materials, optical materials, aircraft engine turbine blades, silicon wafer products, etc. are all commonly ground with diamond grinding wheels.
