Introduction of several kinds of diamond grinding wheel abrasives

Diamond grinding wheel is a commonly used grinding wheel among grinding wheels, and diamond grinding wheel is also strict in the selection of abrasives. The following briefly introduces several commonly used diamond grinding wheel abrasives
1. Chromium steel jade the hardness of chromium steel jade is similar to that of white corundum, but the toughness is better (between brown corundum and white corundum), so the durability and grinding efficiency of the grinding wheel are higher than that of white corundum. At the same time, the contour of the abrasive cutting edge on the surface of the grinding wheel can be maintained for a long time after trimming (that is, the abrasive cutting edge is on the end plane of the same circumferential surface), so under the same conditions. In addition, it is suitable for grinding steel and corundum, and the surface finish of the grinding wheel is slightly higher than that of the steel and corundum. In addition, it is also suitable for grinding the workpiece with chrome and corundum. Chrome corundum has a high price and is only suitable for fine grinding.
2. Single crystal corundum (GD) and microcrystalline corundum (GW) single crystal corundum have high hardness and toughness and good crushing resistance during grinding. It is used for grinding stainless steel and high-temperature high-speed steel with high toughness. High hardness steel has better effect, microcrystalline steel jade has high strength and toughness, and its self sharpening property is better than that of single crystal corundum. It is suitable for grinding stainless steel. Bearing steel and special nodular cast iron can also be used for high finish grinding.
3. The color of black silicon carbide abrasive is black, some are dark blue, and the ceramic bond grinding wheel made of is also black. The hardness of black silicon carbide is higher than that of any kind of corundum abrasive. The abrasive grain has sharp water chestnut, but its toughness is low and fragile. It can not withstand the cutting pressure of materials with high toughness, so it is suitable for grinding materials with low tensile strength or soft materials.
4. The color of green silicon carbide is green, and the ceramic bond grinding wheel made with it is also green. Green silicon carbide has the same hardness as black silicon carbide, but it is more brittle. It is mainly used for grinding cemented carbide. And brittle materials such as optical glass.
5. Diamond has higher hardness than other abrasives. It is the hardest material known at present. It has excellent cutting performance, but the price is too expensive. It is mainly used to process high hardness materials that are difficult to be processed by other abrasives. The grinding wheel made of this abrasive is called diamond grinding wheel. It has many different characteristics from the grinding wheel made of corundum and silicon carbide abrasive.
