It is developed using high-quality diamond powder, media and additives, integrating physical and chemical effects,the particle size distribution is uniform, and the particle shape is spherical and octahedral, so the grinding product is better and less likely to produce scratches,the hardness is extremely high, The cutting edge is sharp and sharp, and has good grinding effect on hard and soft materials. It only produces grinding effect without rolling and does not produce disturbing layers; it is mainly used for mechanical grinding and polishing of hard alloys, alloy steels, high carbon steels and other high-hardness materials. Precision grinding of material parts and metallographic and petrographic samples, etc.
