1 abrasive selection abrasive selections mainly depends on the workpiece material and heat treatment method. a grinding a material of high tensile strength, the selection of the toughness of the abrasive. b. the grinding low hardness, elongation material, the choice of the relatively brittle abrasive. c grinding material with high hardness, the selection of the higher hardness of the abrasive. d. choice easily be processed materials react chemically abrasive.

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.
