<p>The clamping shaft (6) is designed so that in the region of each clamping surface (10) has a shaft radius (r), which seen in a predetermined tool rotation direction (12), ascending from a minimum shaft radius (rmin) away to a maximum shaft radius (rmax) across an angular climb range (alpha 1, fig.3). The shaft radius rises continuously in such a manner, that the clamping surface, in cross section is curved convexly.</p> |
