What are the grinding wheel specification

      First, the classification of grinding wheel specification

      There are two specification to determine the type of grinding wheel: 

      1  The abrasive determines the performance of the grinding wheel specification, the grinding wheel is different, and the optimum range of the grinding wheel is also changed. Specific to the points, the following are the following: white corundum abrasive, chrome corundum abrasive, single crystal corundum abrasive, black corundum abrasive, green silicon carbide abrasive, black silicon carbide abrasive, micro hole grinding wheel, gas hole grinding wheel, grinding wheel, grinding wheel, grinding wheel, grinding wheel, etc..

    2 The final product of the grinding wheel specification is different, and the name is different. Of course, the use is not the same. Preliminary, flat grinding wheel specification(round, the two sides are flat) and shaped grinding wheel specification(irregular wheel). In actual use, flat grinding wheel occupies a dominant position, and shaped grinding wheel because of its variety, offset the inadequacies of the flat grinding wheel. Double bevel wheel, wheel, single convex wheel, single concave grinding wheel, double-sided concave grinding wheel, thin grinding wheel, a barrel type single bevel wheel and cup type grinding wheel, bowl type grinding wheel, disc type grinding, cylindrical grinding head, round cone grinding head, spherical grinding head, square stone, rectangular stone and so on.

    Second, the choice of grinding wheel hardness and use the grinding wheel hardness: the choice of grinding wheel hardness and use, for example, in the course of normal use, the grinding wheel hardness is refers to the grinding wheel sheet sand on the surface in the grinding process of shedding of the degree of difficulty, strong abrasive wheel binder bonded sand process. If the wheel hardness is low, easy to fall off the sand, and the abrasive hardness is high, not easy to fall off. In order to meet the requirements of different grinding process, the grinding specification with various grinding wheel hardness level is required to meet the need of practical use.

     The choice of abrasive hardness is mainly about the grinding efficiency and the surface quality. If the abrasive selection is excellent, it can not be effectively grinding, and easy to burn the work piece; if you choose too soft, will shorten the time to use the tool, increase the cost. Combined with the various conditions of the grinding process, the choice of the national standard of the grinding wheel specification level, for the grinding process, is very important.
