Selection of grain size

The grain size mainly influences the material removal rate and the quality of surface respectively cutting edge. It also affects the lifetime of the grinding tool. On the one hand it is a matter of fact that the material removal rate is higher if a coarser grain size is chosen. A finer grain size, on the other hand, improves the surface.
