Microscopic Analysis Of Diamond Grinding Wheel Loss

  Microscopic analysis of diamond grinding wheel loss

  The application of diamond grinding wheel under microscope under various grinding conditions can be investigated in detail, and the results are as follows:

  Under the condition of low grinding force and grinding speed, diamond grinding wheel is used, its appearance is scattered with many sharp sharp, reflective diamond abrasive wear facets, this is because the diamond abrasive and superhard data mechanical conflict and mechanical wear. This kind of wear is gradually carried out, the wear of abrasive grains and grinding stroke length is proportional to the case contact.

  Under the grinding condition of high temperature in grinding zone, the diamond abrasive grains on diamond grinding wheel are oxidized and graphite-depleted. According to the properties of diamond, the degree of oxidation and graphitization depends on the crystal integrity of diamond abrasive, and the degree of graphitization is related to crystal orientation. The diamond abrasive with good crystal integrity has low degree of oxidation and graphitization loss.

  Diamond Grinding wheel on the appearance of some of the diamond particles attack some cracking and fragmentation, resulting in the whole grain falling. Because the crystal cleavage is by the crystal structure element 7 Chemical bond type, intensity and spread of the plane break, it is often along the chemical bond strength end of the azimuth surface attack. The randomness of the dispersion of abrasive grains, the resolution of its attack and cleavage damage is not to be prevented.

  Diamond abrasive grains are cracked and broken, and the fracture is irregular. Grinding process, grinding particles instantaneous rise to high temperature, and in the effect of grinding fluid in the cold, repeated repeatedly, in the abrasive appearance of a large amount of thermal stress, so that the appearance of grinding particles broken. Thermal stress breaking and wear and diamond abrasive particles of the shortcomings of dispersion and oxidation, graphitization have close contact, so first in the surface defects in the abrasive crystal attack some thermal stress gathered, induced multiple cracks attack and expansion. In the effect of grinding force, the weakest of the intensity of some attacks broken. The crushing and falling of abrasive grains is the result of grinding and grinding heat.
