For example: 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. The abrasive has good grinding performance, wide adaptability, low price, and 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.
Chrome corundum grinding wheel: suitable for grinding tools, measuring tools, instruments, threads and other workpieces with high surface processing quality requirements.
Single crystal corundum grinding wheel: suitable for grinding materials with high toughness and hardness such as stainless steel and high vanadium high speed steel, as well as workpieces that are easy to deform and burn. Microcrystalline corundum grinding wheel: suitable for grinding stainless steel, bearing steel and special nodular cast iron. Used for forming grinding, cutting grinding and mirror grinding.
Therefore, the appropriate grinding wheel must be selected according to the specific conditions (such as the material properties of the workpiece, heat treatment method, shape and size of the workpiece, processing form and technical requirements, etc.). Otherwise, improper selection of grinding wheel will directly affect machining accuracy, surface roughness and production efficiency. Wang Cai
