In cases where the diameter of the grinding tools is not determined by the size and shape of the workpiece to be machined, it generally must be defined based on the proper grinding speed (Vs).
It therefore generally applies that, with larger grinding
tool diameters, the more favorable ratio of the grinding circumference
to the working length positively influences the operating
efficiency. The abrasive grit is subjected to less stress
due to a longer passive phase, thus prolonging the life of
the grinding tool.
In grinding tools used for shape and profile grinding, the
larger diameter yields an improvement of the profile retention.
It is often advisable to adapt the speed of the grinding
spindle to the optimal conditions of the grinding tool.
