Wheel hardness selection

Wheel hardness refers to the degree of difficulty on the abrasive grinding wheel surface under the force of falling. Wheel hardness soft, abrasive grinding wheel showing off easily, the hardness of the ceramic diamond disc hard, showing off abrasive difficult. Hardness and abrasive grinding wheel hardness are two different concepts. With an abrasive wheel can be made of different hardness, which is mainly determined by the binding agent performance, quantity and wheel manufacturing processes. Significant differences are grinding and cutting wheel having a "self-sharpening", select the hardness of the stainless steel flap disc, in fact, choose self-sharpening wheel, hope still sharp abrasive grains fall off too early, do not blunt the not fall off .
