    Diamond grinding wheel due to its excellent grinding performance, widely used in all kinds of high performance, precision and ultra precision grinding of hard and brittle materials, but because the diamond grinding wheel since the sharp difference, easy to plug, easy to produce vibration force caused by eccentric wheel in grinding process, because of the stability of the grinding process and workpiece the quality of grinding surface, thus limiting the normal use of diamond grinding wheel, therefore must be regular dressing, but the existence of the traditional mechanical dressing method of dressing time long, the difficulty is big, efficiency is low, the precision is not high. Diamond grinding wheel dressing technology and therefore the development of high efficiency, high precision is the key technology of hard and brittle materials, precision and ultra precision grinding, high speed and high efficiency grinding, grinding, grinding automation.
    Super hard abrasive diamond grinding wheel is used more and more widely, the amount of about 1 per year growth rate of midazolam, save the grinding time and processing costs a lot, diamond is one of the most hard materials, the coefficient of friction coefficient is small, good wear resistance, so the diamond grinding wheel made of high grinding ability, abrasives consumption is small, the grinding temperature is low, more and more widely used in optical glass, ceramics, semi allogeneic hard alloy, precious stones and other non metal cutting, grinding of hard and brittle material.
    Diamond grinding wheel is usually composed of diamond and non diamond layer and the substrate layer, composed of three parts. The bond is the role of the abrasive grains bonded together, the grinding wheel has the strength, the hardness and porosity, corrosion resistance, resistance to damp, for bond diamond grinding wheel with metal, resin, ceramic etc.; commonly used is the metal bonded diamond the metal bond grinding machine has the advantages of high strength, good wear resistance, a good electric, and keep good, the advantages of large bearing load in high performance hard brittle materials grinding and precision, ultra precision grinding has been applied widely, but the diamond grinding wheel self dressing, easy to plug, in poor the grinding process is easy to produce vibration force caused by the grinding wheel eccentricity, thus affecting the stability of the grinding process and the grinding surface quality, thereby limiting their use in precision machining of hard and brittle materials of high performance, therefore must be regular dressing, diamond grinding wheel dressing time however there 戈修 whole difficulty is big, the low efficiency of dressing the characteristics of. Therefore the development of high performance, high quality diamond grinding wheel dressing technology is the key technology of hard and brittle materials precision and ultra precision grinding, high speed and high efficiency grinding, grinding, grinding automation.
