Through multiple random grinding, abrasive four weeks will be a lot of debris adhering

   Most of the grinding process the input power into the grinding heat, the grinding point temperature up to 1200K or more, at such a high temperature under the action of  polycrystalline diamond  first case of air quickly oxidized to form low melting point metal oxide, followed by the metal oxide was heated at high temperature in the grinding zone melting state, covering the surface of the wheel when the wheel again on the surface of this part in the grinding, the grinding force of the, some pushed open,  cutting tools , increased affinity and adhesion of the grinding wheel, as well as the adhesion of the workpiece surface is pressed ridge groove surface. Through multiple random grinding, abrasive four weeks will be a lot of debris adhesion, the grinding force increases, the temperature rises,  Synthetic diamond  a vicious cycle, increasing congestion, until the grains broken or fall off, which is melted adhesive .
Chemical affinity between the different elements are bonded blockage is another important reason. And the grinding abrasive material in the heat exposure, the temperature factors to enhance their activity, increased affinity, when have certain conditions, leads to chemical reactions, the abrasive particles and debris on the wheel surface ability to produce a loss of cutting crystals.
