Wheel of life

In the grinding process, with the wheel itself wear, wheel face state is changing. The longer the time, the lower the cutting ability of the grinding wheel, a variety of grinding defects will continue to emerge, the grinding not up to standard. Then it must trim grinding wheels to reach normal state. We usually refer to is the actual grinding wheel life time in two trim wheel between. Wheel length of life directly affects the grinding effects, especially more important for profile grinding.
