How to make a diamond grinding wheel wear slower reasons

Diamond Wheel in our daily lives has become so widespread, that how can you wear diamond wheel is often slow, you know? If you do not know to give with Xiaobian look at it.
Select the diamond grinding wheel hardness general principle is: the processing of soft metal, in order not to make premature loss of abrasive, then use a hard wheel. Wear resistance and long life. Diamond grinding wheel ratio up to 3500-5500, a hundred times higher than normal corundum grinding wheel, 3-5 times higher than ordinary diamond wheel. When  GUSHI diamond polishing tools processing hard metal, in order to make timely blunt grit off, thereby exposing new abrasive grains with sharp edges (ie, self-sharpening), use a soft wheel. Or because the soft material in the grinding wheel abrasive wear is slow work, without departing too early; latter is because the grinding of hard materials, abrasive wear of the grinding wheel work faster, require faster updated. High efficiency, good overall economic efficiency. Grinding sharp, small grinding force, diamond grinding wheel dressing cycle length, less the amount of dressing, long replacement time; long life cycle, grinding ratio, getting a better economy, use good shape retention, without regular Replace the wheel and wheel dressing, saving time and improving working conditions conducive to machining operations. In the grinding force and grinding conditions are low speed after using diamond grinding wheel, and its distribution on the surface of a large number of angular, consistent diamond abrasive wear reflective facets. This is GUSHI circular blades  mechanical wear due to mechanical friction and superhard abrasive diamond material produced. This wear is gradual, with the amount of wear of the abrasive grinding stroke length proportional relationship.
At higher temperatures the grinding conditions grinding zone, diamond grit diamond wheel on and graphite oxidation and loss. According to the nature of the diamond understood, oxidation, depending on the degree of graphitization of the diamond abrasive crystals integrity, and the degree of graphitization and also on the crystal orientation. Good crystal perfection diamond abrasive, oxidation, low degree of graphitization loss.
On the part of diamond grit diamond wheel surface localized fracture and fragmentation, resulting in whole shedding. Cleavage  GUSHI stone drill bits occurs diamond abrasive damage. Since the crystal cleavage plane of rupture was determined by the crystal structure of factor 7 bond type, intensity and distribution of the generated, which is often generated along the surface of the orientation strength of the final bond. Random distribution of grains to determine their cleavage occurred damage is inevitable.
