Patent ID: 10828739

Abstract:
The invention relates to a tool holder (10) which is embodied for rotation around a tool holder rotation axis (D) and which comprises at its one axial longitudinal end (10a) a tool segment (14) for receiving a tool, and at its other axial longitudinal end (10b) a coupling segment (16) for torque-transferring coupling to a machine tool (78), a measurement apparatus (28) for sensing data relating to the operation of the tool holder (10) being provided on the tool holder (10), which apparatus encompasses at least the following components:—at least one sensor (30, 32, 34, 36) supplying a sensed signal;—a signal transfer apparatus (38) for transferring a measured signal;—an electrical circuit (40) connected in signal-transferring fashion to the sensor (30, 32, 34, 36) and to the signal transfer apparatus (38); and—an energy supply apparatus (42) that is connected to the signal transfer apparatus (38) and to the electrical circuit (40). According to the present invention the tool holder (10) comprises a tool holder main body (12) that comprises both the tool segment (14) and the coupling segment (16), at least one component from among the sensor (30, 32, 34, 36), electrical circuit (40), and energy supply apparatus (42) being received in a recess (56, 62) in the interior of the tool holder main body (12).
