Wheel must be used with safety guards. The actual rotational axis of the wheel and its axis of rotation through the center of mass deviation from parallel state called static unbalance wheel. This is usually due wheel uneven density, both ends of the hole and the surface is not parallel or coaxial cylindrical deviation has caused.

FRP glass fiber reinforced plastic is actually, a glass fiber and epoxy or phenolic resin conjugate
FRP is not tempered. FRP glass fiber reinforced plastic is actually, a glass fiber and epoxy or phenolic resin combination, fiberglass epoxy phenolic resin binder is a glass fiber filler, adding a small amount of cubic boron nitride thermosetting plastic. Especially the content of more than 90% of high silica glass and steel, the cutting process, cutting tools abrasive nature of the tool wear serious, the workpiece from the floor, dregs, dust seriously. Resin due to high cutting temperature and charred. synthetic diamond, steel, grade diamond tools with the following process characteristics: high tool life, turning finish; processing efficiency, the use of cutting fluid grade is generally not carried out dry cutting; If for high speed or workpiece causes poor thermal conductivity cutting temperature is too high, we can use water-based cutting fluid for cooling.
