Wheel hardness and hardness selection

Grinding wheel hardness hardness and choice reaction wheel abrasive grains hardness of the grinding force, the grinding wheel surface from the ease of shedding. Wheel hardness is hardness that  cut off disc is different from the hardness of the abrasive grinding wheel hardness. Wheel hardness should be noted that when used properly, if it is too hard dulls the abrasive untimely loss will generate a lot of heat to burn the workpiece; wheel is too soft, then make the grit off too fast and can not be fully effective.
The hardness of grinding wheel selection principle:
Work harder, softer wheel;
Contact surface of the grinding wheel and the workpiece larger wheel selection softer;
Grinding and profile grinding wheel should be  velcro disc selected hard to maintain the required shape precision grinding. Resin grinding wheel for use with Performance Wheel "> resin grinding wheel grinding wheel to lure large pores, clogging when the grinding wheel, so the grinding efficiency is high, it is widely used in soft metals and plastics cast iron, stainless steel, hard rubber, leather and other non-metallic materials grinding, when used with rapid cooling characteristics, especially suitable for thin workpieces and grinding due to thermal deformation of the workpiece, abrasive than the average high efficiency, but also can be produced according to user needs .
Resin grinding wheel pores present in the  nonwoven belt domestic production of grinding wheels up to 70% porosity, can replace imported products, especially for grinding plastics and rubber products, grinding heat faster, high precision grinding, grinding efficiency, and wear resistance are close to or over imported products water products.
