Grinding Wheel production of the grinding wheel hardness refers to the degree of difficulty in falling under the action of the grinding force of the abrasive grains on the grinding wheel surface. Soft hardness of the grinding wheel, said abrasive grains of the grinding wheel is easy to fall off, the hard Grinding Wheel select the hardness of the grinding wheel, said abrasive grains harder shedding. The hardness of the grinding wheel and the hardness of the abrasives are two different concepts.
The Grinding Wheel adopted with an abrasive can be made of different hardness of the grinding wheel, and it is mainly determined by the performance of the binding agent, quantity, and the wheel manufacturing process. The significant difference of grinding and cutting wheel has a "self-sharpening", select the hardness of the grinding wheel, in fact, is to choose the self-sharpening of the grinding wheel, also sharp abrasive particles do not fall off too early, do not blunt not fall off .
