Diamond grinding wheels are commonly used among grinding wheels, and their selection of abrasives is also quite strict. Below is a brief introduction to several commonly used diamond grinding wheel abrasives1. Chromium steel jade has a hardness similar to that of white corundum and good resistance (between brown corundum and white corundum), so the durability and grinding power of the grinding wheel are higher than that of white corundum. After simultaneous trimming, the contour of the abrasive cutting edge on the surface of the grinding wheel can be maintained for a long time (i.e., the abrasive cutting edge is located on the same circumferential surface end plane), therefore under the same conditions. The surface smoothness of the workpiece ground with chromium corundum grinding wheel is slightly higher than that with white corundum grinding wheel. Due to the above characteristics, chromium corundum is suitable for grinding various hardened high-strength steel materials, as well as measuring tools and instrument parts with high smoothness requirements. In addition, it is also suitable for forming grinding and edge grinding of cutting tools. Chromium steel jade has a higher price and is only suitable for precision grinding.

2. Single crystal corundum (GD) and microcrystalline corundum (GW) single crystal corundum have high hardness and resistance, and are resistant to fragmentation during grinding. Used for grinding stainless steel and high-temperature high-speed steel with high resistance. Steel with high hardness performs better, and microcrystalline corundum has high strength, good resistance, and better self sharpening than single crystal corundum, making it suitable for grinding stainless steel. Bearing steel and special ductile iron can also be used for high finish grinding.3. The color of black silicon carbide abrasive is black, and there are also dark blue ones. The ceramic bonded grinding wheel used for manufacturing is also black. Black silicon carbide has a higher hardness than any other type of abrasive such as corundum, with sharp diamond corners but low and fragile resistance. It cannot withstand the cutting pressure of materials with high resistance, making it suitable for grinding materials with low tensile strength or soft materials.4. The color of green silicon carbide is green, and the ceramic bonded grinding wheels made from it are also green. Green silicon carbide has the same hardness as black silicon carbide, but is more brittle and is primarily used for grinding hard alloys. Optical glass and other brittle materials.5. Diamond has a higher hardness than other abrasives and is currently the hardest known material. It has excellent cutting performance, but its price is expensive. It is mainly used for processing high hardness materials that are difficult to machine with other abrasives. The grinding wheel made with this type of abrasive is called a diamond grinding wheel, which has many different characteristics compared to grinding wheels made with corundum and silicon carbide abrasivesArticle source: Diamond grinding wheelhttp://www.jm-nanhua.com
