Abstract
A tool turret includes a tool disk (1) having at least one tool receptacle (7) for a machining tool and being fastened to an accommodating disk (51). The disk can be swiveled about a support column that defines a swivel axis into positions in which the particular machining tool is in a working position. A contact surface (55) is provided on the tool disk (1) and can be clamped to an accommodating surface (53) on the accommodating disk (51) by a clamping device. The clamping device has an annular groove on one disk to be clamped. The annular groove is concentric to the swivel axis, is open radially outside and has at least one inner slanted surface (81). At least one compression piece (57) is on the other disk, penetrates the annular groove (61) under compressive force and has a wedge surface (79). In interaction with the slanted surface (81) of the annular groove (61), the wedge surface produces a force component as a clamping force from the compressive force pressing the contact surface (55) and the accommodating surface (53) against each other.
