Rotierend angetriebener Fräskopf

摘要

The working of the back of a book block (18) of pressed-together printed sheets by a cutting process requires the process to be carried out in one operating cycle with one cutting tool in two cutting stages, in which the first cutting stage has a higher cutting speed than the directly following second cutting stage. To this end, a rotatively driven cutter head (1) is used, the tip holder (3) of which has cutting edges (5) on the periphery at the front end, to which cutting edges (5) a raised cutting edge (6) is allocated which is set back radially towards the axis (7) of rotation.
