With the continuous development of the abrasive industry, grinding wheels have become an indispensable part of our lives. The most commonly used abrasives for grinding wheel customization are brown corundum and white corundum. This is followed by black silicon carbide and green silicon carbide. The other commonly used ones are chrome corundum, single crystal corundum, microcrystalline corundum, and zirconium corundum.

Brown corundum grinding wheel

Brown corundum has high hardness and high toughness. Suitable for grinding metals with high tensile strength. Such as carbon steel, alloy steel, malleable cast iron, hard bronze, etc. This abrasive has good grinding performance and wide adaptability. It is often used for rough grinding with a large margin, and it is cheap and can be widely used.

White corundum grinding wheel

The hardness of white corundum is slightly higher than that of brown corundum, and the toughness is lower than that of brown corundum. During grinding, the abrasive grains are easily broken. Therefore, the grinding heat is small. It is suitable for the manufacture of grinding wheels for fine grinding hardened steel, high carbon steel, high speed steel and thin-walled parts. The cost is higher than that of brown corundum.

Black Silicon Carbide Grinding Wheels

Black silicon carbide is brittle and sharp, and its hardness is higher than that of white corundum. Suitable for grinding materials with low mechanical strength. Such as cast iron, brass, aluminum and refractory materials.

Green silicon carbide grinding wheel

Green silicon carbide has higher hardness and brittleness than black silicon carbide. The abrasive grains are sharp and have good thermal conductivity. It is suitable for grinding hard and brittle materials such as cemented carbide, optical glass and ceramics.

Chrome corundum grinding wheel

It is suitable for grinding tools, measuring tools, instruments, threads and other workpieces with high surface processing quality requirements.

Single crystal corundum grinding wheel

It is suitable for grinding stainless steel, high-vanadium high-speed steel and other materials with high toughness and high hardness, as well as workpieces that are easily deformed and burned.

Microcrystalline corundum grinding wheel

Suitable for grinding stainless steel, bearing steel and special ductile iron, etc. For profile grinding, plunge grinding, mirror grinding.

Zirconium corundum grinding wheel

It is suitable for grinding austenitic stainless steel, titanium alloy and heat-resistant alloy, especially for heavy-duty grinding.
The grinding wheel corresponding to the workpiece can improve the work efficiency a lot, don’t use it wrong.
