Abstract
A tool and workpiece arrangement for material-removing machining includes a primary holder and a replaceable secondary holder which is mounted on the primary holder, and which carries a tool or a workpiece. The primary holder is provided at its end face, which cooperates with the secondary holder, with portions which extend crosswise with respect to one another around an unprofiled central region at mutually displaced sides so as to be parallel at respective mutually opposite sides, and which have respective flanks. The corresponding end face of the replaceable secondary holder is contoured in a corresponding or complementary manner. Due to the cooperation of the juxtaposed flanks of the profiled portions of the primary holder with those of the secondary holder, there is attached a self-centering effect with a highly repeatable degree of accuracy, and with a positive engagement in the direction of three mutually perpendicular axes, so that axial and radial bending forces as well as torques can be transmitted without any oscillations. The primary and secondary holder are clamped to one another by either a manually operable or an automated clamping arrangement. |
