The abrasives used are mainly brown corundum, white corundum, black silicon carbide and green silicon carbide, etc. :

1, brown corundum high toughness, suitable for grinding carbon steel, alloy steel, malleable cast iron, hard bronze and other high tensile strength materials;

2, white corundum than brown corundum has higher hardness, cutting and grinding performance is better, suitable for quenching steel, high carbon steel, high-speed tools and other materials grinding process;

3, black silicon carbide high hardness, brittle and sharp, suitable for grinding, cutting low tensile strength materials, such as cast iron, glass, ceramics, stone, refractory, etc.;

4, green silicon carbide is more pure than black silicon carbide, suitable for grinding hard alloy, optical glass, gems, agate and other hard brittle materials.
