ABSTRACT:
A tool has independently radially adjustable cutting edges. Adjusting drives are provided for each cutting edge. Each adjusting drive is laterally spaced from, and axially overlaps, an adjacent adjusting drive. Each adjusting drive comprises a servomotor which directly drives a screw. A screw nut is axially movable on the screw and is rigidly connected by means of a bridge with an adjusting piston arranged parallel thereto. The adjusting piston is axially movable and is connected by a bearing to a tubular connecting rod. Axial movement of the latter serves to radially adjust an associated cutting edge of the tool. The connecting rods of the adjusting drives are coaxially and telescopingly arranged.
