PCD, bullnose, profile and cup stone grinding wheel materials

PCD grinding wheel, bullnose grinding wheel, profile grinding wheel and cup stone grinding wheel are all common abrasive tools in our daily life. Its appearance has greatly improved people’s grinding efficiency.

Grinding wheel is an indispensable tool for grinding, and the abrasives it uses are also different. Different types of abrasives use corresponding abrasives. Here is an introduction:

Generally used abrasives are brown corundum and white corundum, followed by black silicon carbide and green silicon carbide.The other commonly used are chromium corundum, single crystal corundum, microcrystalline corundum, zirconium corundum, and emery.

1.Brown corundum:

The hardness and toughness of brown corundum are suitable for grinding metals with higher tensile strength, such as carbon steel, alloy steel, malleable cast iron, hard bronze, etc., this kind of abrasive has good grinding performance and wide adaptability, and is often used to remove large amounts of excess metal. A large amount of coarse grinding is cheap and can be widely used.

2.White corundum grinding wheel:

The hardness of white corundum is slightly lower than that of brown corundum, and its toughness is lower than that of brown corundum. During grinding, the abrasive grains are easily broken. Therefore, the grinding heat is small, and it is suitable for the manufacture of finely ground quenched steel, carbon steel, fast steel and thin grinding. The grinding wheel used for wall parts is more expensive than brown corundum.

3.Black silicon carbide:

Black silicon carbide is brittle and sharper than white corundum, and is suitable for grinding materials with lower mechanical strength, such as cast iron, brass, aluminum and refractory materials.

4. Green silicon carbide:

Green silicon carbide is harder and brittle than black silicon carbide, with sharp abrasive grains and good thermal conductivity. It is suitable for grinding hard and brittle materials such as cemented carbide, optical glass, and ceramics.

There are many types of grinding wheels, and there are various shapes and sizes. Due to the different abrasives, bond materials and manufacturing processes of the grinding wheels, various grinding wheels have different working performances. Each type of grinding wheel has different characteristics according to its own characteristics. A certain scope of application. Therefore, when grinding, a suitable grinding wheel must be selected according to the specific situation.
