Tool holder for tool for deburring and chamfering of curved wall, has fixing portion that is movably supported in direction of rotation axis on coupling against force of spring relative to clamping portion along radial direction

摘要

Tool holder (1) has a rotational axis defining clamping portion (2) that is clamped in a machine tool. The tool is mounted by fixing portion (3) which is rotationally fixed with respect to rotation about rotation axis (6). A fixing portion is supported against the force of first spring (13) movable on the clamping portion through connecting coupling (4). The fixing portion is movably supported in direction of rotation axis on coupling against the force of a second spring (24) relative to the clamping portion along radial direction.
