Brown corundum grinding wheel: Brown corundum has high hardness and good toughness, and is suitable for grinding metals with high tensile strength, such as carbon steel, alloy steel, malleable cast iron and hard bronze. This kind of abrasive has good grinding performance and wide adaptability, and is often used for rough grinding with large allowance, and its price is cheap, so it can be widely used.
White corundum grinding wheel: The hardness of white corundum is slightly higher than that of brown corundum, but the toughness is lower than that of brown corundum. Abrasive particles are easily broken during grinding, so the grinding heat is small. It is suitable for manufacturing grinding wheels for fine grinding hardened steel, high carbon steel, high speed steel and grinding thin-walled parts, and the cost is higher than that of brown corundum.

There are many kinds of grinding wheels. According to the abrasives used, it can be divided into ordinary abrasives (corundum and silicon carbide, etc. ), natural abrasives, superhard abrasives and grinding wheels (diamond and cubic boron nitride, etc.). ). According to the shape, it can be divided into plane grinding wheel, inclined grinding wheel, cylindrical grinding wheel, cup grinding wheel and dish grinding wheel. According to the binder, it can be divided into ceramic grinding wheel, resin grinding wheel, rubber grinding wheel and metal grinding wheel.
The characteristic parameters of grinding wheel mainly include abrasive, particle size, hardness, binder, shape and size. Because the grinding wheel usually works at high speed, before use, it is necessary to carry out rotation test (to ensure that the grinding wheel will not break at the working speed) and static balance test (to prevent the vibration of the machine tool when working).
