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.

Diamond one of the most significant features
PCD is a synthetic diamond single particle basis by a special process of production from the current sintering mechanism in Diamond blade with polycrystalline diamond can be roughly divided into three types, namely, sintered, growth pattern and growth - sintered. The main product is sintered, the polycrystalline diamond powder as the raw material is, there is no additive or additives and high temperature and abrasive grinding conditions, so that the bulk of the sintered agglomerate, its structure and cappuccino that much similar grain disordered, no direction, no cleavage plane. This is the most synthetic diamond features of the diamond one, so in the course of a micro blade broken, and will not occur in brittle fracture under shock loading, chipping caused by non-cutting wear and tear damage. In this way, the service life can be significantly extended.
