What role does electroplated diamond grinding wheel play in diamond grinding tools?
Electroplated diamond wheel is widely used in high-speed and ultra-high-speed grinding, high-performance grinding of difficult to machine materials, forming grinding and other machining fields because of its excellent grinding performance and grinding surface quality. Diamond grinding wheel takes diamond abrasive as raw material and metal powder, resin powder, ceramic and electroplated metal as binder respectively. The circular consolidated grinding tool with a through hole in the center is called diamond grinding wheel (alloy grinding wheel). Electroplated diamond grinding wheel has longer service life, can be cut freely, self-tuning and grinding, and improve grinding efficiency. It is a good choice for automatic equipment grinding. The grinding forming of low carbon steel is to scrape off the binder by the flowing chips formed when grinding low carbon steel with CBN grinding wheel, so as to achieve the purpose of forming. This method can be divided into single drum method and double drum method. Double drum method uses the speed difference between two drums to realize smooth forming, which can improve the forming quality. Low grinding efficiency, unstable forming and dressing of carbon steel.
Advantages of electroplated diamond grinding wheel:
Electroplated diamond grinding wheel has high grinding efficiency and is not easy to generate heat and agglomerate in the grinding process. Powder metallurgy is used to solidify small-sized diamond particles on cemented carbide matrix to manufacture flake dresser. The hardness of diamond grinding wheel determines the main characteristics of diamond grinding wheel. It can grind hard materials such as cemented carbide, glass and ceramics efficiently, and the service life of grinding tools is long. The advantage of dressing CBN grinding wheel with diamond chip dresser is that the cost is low, and the performance of chip dresser changes little after wear. Therefore, it can be trimmed with a large dressing feed without increasing the surface roughness of dressing grinding wheel.
Electroplated diamond grinding wheel has small grinding force and low grinding temperature. Structural parts: cemented carbide is used for a variety of products of structural parts, such as rotating seal ring, press piston, lathe chuck, grinder spindle, bearing journal, etc.
Electroplated diamond grinding wheel has high precision, good surface quality and good shape retention. It combines diamond / CBN abrasive particles to form a wheel shape, and keeps the abrasive particles easy to drip when subjected to cutting reaction. It is composed of resin and filling materials. Diamond grinding wheel takes diamond abrasive as raw material and metal powder, resin powder, ceramic and electroplated metal as binder respectively. The circular consolidated grinding tool with a through hole in the center is called diamond grinding wheel (alloy grinding wheel). There are many dressing methods for ceramic grinding wheel, among which diamond roll dressing method has good effect, and the appropriate dressing method can be selected according to the actual operation. The characteristic of CBN grinding wheel dressing method is to avoid the influence on CBN abrasive particles and directly etch the binder. Therefore, among various CBN grinding wheel dressing methods, free abrasive particle dressing method has better effect.
