Abstract

Components (36,37) are provided to rotate the grinding spindle (29) around its longitudinal axis. The grinding plate (43) at the working end of the spindle has a specific radial extension at right-angles to the rotation axis of the spindle. On its side facing the pin drill crown, the grinding plate has an endless track which is concentric to its rotation axis. - The grinding spindle rotary axis forms an angle in the interval between 30 and 60 deg. with the longitudinal central axis of the pin to be ground. Components are also provided to produce a relative movement between the grinding plate and the pin.
