Grinding wheel: Central abrasive and a binder resin made of a circular abrasive through hole. Abrasive wheel is the most widely used as a maximum amount, the use of face, high-speed rotation, can the outer, inner circle, plane type and various other metal or non-metal surface of the workpiece when using coarse grinding, fine grinding and half grooving and grinding and cutting and so on.

Grinding wheel is the most important for a class of abrasive. Abrasive wheel is added to the binding agent, a porous body through compacts made of dried and calcined. Due to the abrasive, bond and different manufacturing processes, a large difference in characteristics of the wheel, so the grinding process quality, productivity and economy have an important impact. The characteristics of the wheel mainly determined by the abrasive particle size, binder, hardness, structure, shape and size and other factors.
1 classificationWheel variety.
The press can be divided into ordinary abrasive abrasive (corundum and silicon carbide) abrasive grinding wheel and the natural and super abrasive (diamond and cubic boron nitride) grinding wheel;According to the shape can be divided into flat-shaped grinding wheel, bevel wheel, cylindrical grinding wheel, cup wheel, disc wheel and so on; press binding agent can be divided into ceramic wheel, resin wheel, rubber wheel, metal grinding wheel. The main parameters of the abrasive wheel, viscosity, hardness, binding agents, shape, size and so on.
Since the wheel typically operate at high speed, before turning test should be carried out so that the use of (guaranteed wheel at the maximum operating speed, 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 the correct geometry.
