Selection of abrasivesThe most commonly used abrasives are brown corundum (A) and white corundum (WA), followed by black silicon carbide (C) and green silicon carbide (GC), the rest commonly used are chromium corundum (PA), single crystal corundum (SA), microcrystalline corundum (MA), zirconium corundum (ZA).Brown corundum grinding wheel: Brown corundum grinding wheel has high hardness, toughness, suitable for grinding metals with high tensile strength, such as carbon steel, alloy steel, malleable cast iron, hard bronze, etc. This kind of abrasive has good grinding performance, wide adaptability, is often used to remove a large margin of coarse grinding, cheap, can be widely used.
White corundum grinding wheel: white corundum hardness is slightly higher than brown corundum, toughness is lower than brown corundum, in grinding, abrasive particles are easy to break, therefore, grinding heat is small, suitable for grinding quenched steel, high-carbon steel, high-speed steel and grinding thin-walled parts of the wheel, the cost is higher than brown corundum.
Black silicon carbide grinding wheel: Black silicon carbide grinding wheel is brittle and sharp, harder than white corundum, suitable for grinding low mechanical strength materials, such as cast iron, brass, aluminum and refractories.
Green silicon carbide grinding wheel: green silicon carbide grinding wheel has higher hardness and brittleness than black silicon carbide, sharp abrasive particles, good thermal conductivity, suitable for grinding hard and brittle materials such as cemented carbide, optical glass, ceramics.If you want 180*6*22mm metal grinding disc and China cheap grinding disc price, please visit our website.
