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.

Abrasives mechanical strength mainly tensile, flexural, compressive strength and impact strength
Abrasives mechanical strength mainly tensile, flexural, compressive and impact strength. Since the high-speed rotary wheel to produce large centrifugal force, so that the internal tensile stress in the main. Thus, the level of the Diamond blade and the degree of Polycrystalline diamond be broken. Compared with the compressive and flexural strength, tensile strength are generally lower. Empirical data show that: Synthetic diamond flexural tensile strength is about 1/2 to 1/3. A compressive strength of 1/5 to 1/9. So abrasive tensile strength to meet its rotation resistance to stress generated when the request is the first condition of safe use of abrasive.
