Diamond wheel made of boron carbide, silicon carbide, corundum and general abrasive grinding wheel edge angle sharp, wear, long life, high productivity, good processing quality, but the price is expensive, making it suitable for fine grinding carbide, ceramics , semiconductor and high hardness brittle difficult to machine materials. The diamond wheel comprising the abrasive type, particle size, hardness, concentration, binding agents, wheel shape and dimensions. Abrasive: widely used artificial diamond (JR), according to its crystalline shape and intensity of particles, in a variety of models, select models according to their particular purpose. Granularity: workpiece roughness, of grinding productivity and diamond consumption three aspects to consider. Hardness: resin bonded diamond grinding wheel have characteristics of "hardness". The general use of the S (Y1) level or higher.

Cubic boron nitride particles, the cubic boron nitride (CBN) grinding wheel, stick, in the general wheel surface, only a thin layer, the abrasive toughness, hardness, durability is corundum class grindstone 100 times, the most suitable for the processing of high hardness, tack large, high-temperature, high strength, low thermal conductivity, the hard grind steel and high-speed or ultra-high-speed grinding. Plays a complementary role in its range of applications and synthetic diamond. Diamond grinding wheels grinding carbide and non-metallic materials, has a unique effect, but when grinding steel material, especially grinding specialty steel, the effect is not significant. Cubic boron nitride grinding wheel is the efficiency of the steel is higher than corundum class wheels nearly a hundred times, five times higher than diamond wheel, but not as diamond grinding brittle materials. Cubic boron nitride grinding wheel selection and the selection of the diamond grindstone similar. However, in the selection of binding agent, most resin binder, followed by electroplating, metal binding agent. Vitrified CBN grinding wheel is mainly used for the grinding of black metal titanium alloys, high-speed steel, malleable iron and other difficult to machine, resin bond CBN grinding wheel suitable for grinding ferromagnetic material, is the ideal choice for steel processing. The concentration of CBN grinding wheel generally choose between 100% to 150% more economical reasonable, it does not need a special cutting with ordinary cutting fluid, liquid.

The large pores wheel grinding can not easily be blocked, high durability and cutting ability. Soft metal and plastic, rubber and leather and other non-metallic materials suitable for the coarse and fine grinding. The same time, it has the characteristics of rapid cooling, grinding heat-sensitive material, thin-walled workpieces and dry grinding process (for example, sharpening carbide cutting tools and machine tool guide, etc.) have a good effect. The large pores wheel and ceramic bonded grinding wheel manufacturing method is essentially the same. The different point is porogen plus a certain amount of growth in the ingredients, it is in the grinding wheel before sintering completely volatilized or burned embers, thereby generating large pores. Large pores wheel production range: abrasive generally opt for carbide and corundum, used black silicon carbide (C), green silicon carbide (GC) and white fused alumina (WA) and several high hardness abrasive resistance crisp and sharp, having a good thermal and electrical conductivity; abrasive particle size (~ 180 # 36 #); binding agent (ceramics binding agent); hardness (G ~ M levels); shape (flat-shaped, cup-shaped, bowl-shaped or dish shape, etc.); pore size (approximately 0.7 to 1.4 mm).
