The problem of side grinding with brown corundum grinding wheels is that according to regulations, using a circular surface as the working surface of the grinding wheel is not suitable for side grinding. This type of grinding wheel has a high radial strength and a low axial strength. When the operator applies too much force, it can cause the grinding wheel to break and even injure people. This behavior should be prohibited in actual use.
Brown corundum grinding wheel: Brown corundum has high hardness and toughness, making it suitable for grinding metals with high tensile strength, such as carbon steel, alloy steel, malleable cast iron, hard bronze, etc. This type of abrasive has good grinding performance and wide adaptability, and is commonly used for rough grinding with large margins. 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, while its toughness is lower than that of brown corundum. During grinding, the abrasive particles are prone to fragmentation. Therefore, the grinding heat is low, making it suitable for manufacturing grinding wheels for precision grinding of quenched steel, high carbon steel, high-speed steel, and thin-walled parts. The cost is higher than that of brown corundum.
