    摘要： The invention relates to a machine tool comprising a motor-driven machine spindle (12) which can be rotated about a spindle axis (20). The machine spindle comprises a tool holder (28) arranged at the face. A tool is exchangeably arranged on the machine spindle (12). The tool has a coupling element (32) which is compatible with the tool holder (28) of the machine spindle (12). The coupling element (32) has a rear surface (34) pointing toward the machine spindle (12). The tool holder (28) comprises a face (30) arranged opposite of the rear surface (34) of the coupling element (32). The machine tool comprises at least one galvanic contact point (38) for the electric current or data transmission, said point being arranged between the machine spindle (12) and the tool (36) and rotating together with the machine spindle (12). The galvanic contact point (38) has a contact element (44) which is arranged at the face (30) of the tool holder (28) on the spindle side, and a contact element (46) which is arranged on the rear surface (34) of the coupling element (32) on the tool side. The contact element (44) arranged on the spindle side and the contact element (46) arranged on the tool side can be moved relative to each other by the action of a centrifugal force component occurring during the rotation of the machine spindle (12) about the spindle axis (20) and can be pressed against each other to make contact.

    摘要： The invention relates to a rotary transmitter (2) for machine tools, having an inductive energy transmission section (31), which is arranged between a stator part (4) fixed to the machine and a rotor part (6) fixed to the tool, and a contactless bidirectional data transmission section (35). A special feature of the invention consists in that, in order to make maximum use of the capacity of the energy transmission section (31), precautions are taken with which the optimal operating frequency (f
    opt ) of the energy transmission operating according to the transformer principle is determined at every system start in a test run with a connected test resistor (51) and a variable frequency (f
    p ). Furthermore, for the purpose of interference-free data transmission, buffer storage of the data to be transmitted via the data transmission section (35) is proposed, which data are synchronised in predefined time windows with interference-free periods of the energy transmission.

    摘要： The invention relates to a machining center for work piece machining. The machining center comprises a machine frame (12), a machine spindle (10) driven by a motor and rotatably arranged on the machine frame (12), and a group of machine tools (18) that can be exchanged on the machine spindle. The machine tools comprise a coupling shaft (16) that is compatible with a holder (14) of the machine spindle. Furthermore, a rotary transmitter (22) for electric energy is provided, having a stator (24) fixed to the machine in a stationary manner and a rotor (26) rotating along with the machine spindle (10). It is claimed as novel that the rotary transmitter (22) comprises at least two transmission paths for electric energy which can be selected according to the electric power to be transmitted and the rotational speed of the spindle to be set and which can be activated in the coupled state of the machine tool (18). At least one first transmission path between the stator and rotor is designed in a non-contact way, while at least one second transmission path between the stator (24) and rotor (26) is provided with contacting contacts. With said measures, complete machining of the workpieces can be made possible when clamped in the machining center.
