A wide range of wheel:

Press the abrasive can be divided into ordinary abrasive (corundum and silicon carbide, etc.) and natural abrasive grinding wheels and superabrasive (diamond and cubic boron nitride) grinding wheel;
According to the shape can be divided into flat-shaped grinding wheel, bevel wheel, cylindrical grinding wheel, tile granite cutting wheels, disc wheel and so on; by binding agent can be divided into pottery wheel, resin wheel, rubber wheel, metal grinding wheel. The main parameters metal cut off wheels, viscosity, hardness, binding agents, shape, size and the like.
Since the wheel typically operate at high speed, before turning test should be carried out so that the use of (guaranteed at the maximum operating speed of the wheel, do not break) and static balance test (when working to prevent vibrations caused by the machine). Grindstone at work for some time, it should be trimmed in order to restore the grinding performance and correct geometry.
