Diamond grinding wheel is generally divided into two vitrified bond and resin bond, vitrified bond diamond wheel used to machine PCD Polycrystalline Diamond Compact PCBN cubic boron nitride composite sheet, carbide, ceramic knives, blades, grinding parts the end face of the workpiece, the peripheral surface of the chip breaking groove, bevel; resin bond diamond wheel for grinding hard alloy, non-metallic materials, cutting hard and brittle carbide, non-metallic mineral. Such as tungsten carbide, ceramic, agate, optical glass, semiconductor materials and cast iron, stone. CBN grinding wheel is divided into two vitrified bond and resin bond, vitrified CBN grinding wheel is mainly used for cast iron, tool, ceramic evaporation boats, carbide, steel processing, high-speed steel, hardened steel, precious stones, building materials auto parts industry, grinding power, high-speed machining does not burn the workpiece can be corrected and durable advantages. Resin bond CBN wheel for grinding ferromagnetic material, ideal material for processing steel.

????The most commonly used abrasive is corundum (A) and white fused alumina (WA), followed by the black silicon carbide (C) and green silicon carbide (GC), the remaining common chromium corundum (PA), a single crystal corundum (SA) , microcrystalline corundum (MA), zirconium corundum (ZA). ????Corundum grinding wheel: corundum hardness, toughness, suitable for grinding high tensile strength of the metal, such as carbon steel, alloy steel, malleable iron, hard bronze, this abrasive grinding performance, wide adaptability, commonly used in the removal of a larger margin of kibble, cheap, and can be widely used. ????White corundum grinding wheel: white corundum hardness slightly higher than corundum, toughness than brown fused alumina, grinding, abrasive shatter easily, grinding heat, suitable for the manufacture of fine grinding of hardened steel, high carbon steel, high-speed steel and grinding of thin-walled parts with the grinding wheel, the cost is higher than brown fused alumina. ????Black silicon carbide grinding wheel: black silicon carbide is brittle and sharp and hardness than white fused alumina, suitable for grinding lower mechanical strength of the material, such as cast iron, brass, aluminum and refractory. ?????Green silicon carbide grinding wheel: green silicon carbide hardness brittle than black silicon carbide abrasive sharp, good thermal conductivity, suitable for grinding carbide, optical glass, ceramic and other hard and brittle materials.
