Abstract
The cutting insert carrier, in particular for a face milling cutter (2) comprises a tool basic body (4), having a multiplicity of insert seats (5), in which cutting inserts (6) are received. Rotatably fastened to the tool basic body (4) is a setting element, which is realized, in particular, as a curved ring (8) and which has circumferential cams (10), by means of which the clamping levers (12) are actuated for the purpose of fastening the cutting inserts (6) in a locking manner. The setting element (8) enables all clamping levers (12) to be actuated jointly, at the same time, such that all cutting inserts (6) are simultaneously released or locked in their insert seats (5). As a result, the assembly and setup time for insert changing is reduced significantly in comparison with conventional systems.
Claims16
A cutting insert carrier comprising a tool basic body having a plurality of insert seats distributed around the circumference thereof, a plurality of cutting inserts mounted in a respective insert seat, a setting element provided on the tool basic body, a plurality of clamping elements for clamping/unclamping a respective cutting insert, each clamping element comprising an articulated clamping lever having a first lever arm and a second lever arm, the articulated clamping lever attached to the tool basic body in such a way that the articulated clamping lever rotates about a rotation axis to bring the first lever arm into pressing engagement with the respective cutting insert while second lever arm is guided in a constrained manner on the setting element, and wherein plurality of clamping elements are jointly actuated by the setting element to simultaneously clamp/unclamp the plurality of cutting inserts in the plurality of insert seats.
