Effect of the thickness of abrasive grains on the blockage of grinding wheel

Usually, during the use of the grinding wheel, there are often some problems, especially the longer the use time, the more problems, in which the grinding wheel is blocked by a grinding wheel, and the grinding wheel is blocked for many reasons, such as abrasive, wire speed, hardness and Abrasive grain size, etc. may cause blockage of the grinding wheel. Today, let's take a look at the effect of abrasive grain size on wheel blockage:

Different grinding wheels, such as diamond wheel grinding wheels, have different abrasive grain shapes and densities, as well as different sizes, so the blockage during grinding is different. In general, fine and dense abrasive grains can cause blockage. . Due to the small size of the grinding wheel, the density of the abrasive grains is high, the spacing of the abrasive grains is small, and the porosity of the grinding wheel is small. The grinding wheel has more abrasive particles, and the harder cutting produces relatively less debris in the cut product. These voids and voids are quickly filled with debris and powder from the grinding of the grinding wheel. In addition, due to the small number of voids, the heat generated by grinding wheel and workpiece grinding is more difficult to disperse, which accelerates the increase of grinding heat and easily melts some powder, making it easier for the powder to bond with the gap of the grinding wheel.

The coarse abrasive wheel has less abrasive grains, large individual, large cutting edge, relatively large cutting amount, relatively large cutting block, relatively wide gap between abrasive grains, and large cutting block filling speed is not fast. The pores are not easily blocked, and the heat dissipation system is better. This coarse-grained grinding wheel is slower than the fine-grained grinding wheel in the pre-grinding stage, but in the later stage, when the pores and gaps of the grinding wheel are filled with debris and powder, the coarse-grained grinding wheel is more likely to cause clogging than the fine-grained grinding wheel. Because the self-sharpness of the fine-grained grinding wheel is better than that of the coarse-grained grinding wheel at this time, the clogging of the coarse-grained grinding wheel is more serious.
