Grinding wheel is the most important one class of abrasive.

 Grinding wheel is the most important one class of abrasive. Added to the abrasive wheel is binding agent, the green compacts, drying and calcining a porous body made. As abrasives, binders and  tuck point blades manufacturing process is different, the wheel characteristics vary greatly, so the grinding machining quality, productivity and economy have a significant impact. Mainly by the grinding wheel abrasive characteristics, the intensity, binders, hardness, structure, shape and size and other factors. Wheel variety.
Can be divided according to the  polishing pads for granite ordinary abrasives abrasives (corundum and silicon carbide, etc.) and natural abrasive grinding wheels and superabrasive (diamond and cubic boron nitride) grinding wheel;
Shape can be divided according to level grinding wheels, bevel wheel, cylindrical grinding wheels, cup wheels, disc wheel, etc.; binding agents can be classified according to the ceramic grinding wheel, resin grinding wheel, rubber wheel, metal grinding wheel. The wheel parameters are abrasive, viscosity, hardness, binders, shape, size and so on.
Since wheel usually work at high wood saw blades  speed, thus turning test should be carried out before use (guaranteed wheel at the maximum operating speed, not break) and static balance test (to prevent machine vibrations caused by the work). Grindstone at work for some time, should be trimmed to restore grinding performance and correct geometry.
