The invention relates to a machine tool having a machine frame, a motor-driven machine spindle rotatably mounted on the machine frame, and at least one exchangeable processing head on the machine spindle. The processing head comprises a coupling element compatible with a receiving portion of the machine spindle. Furthermore, a rotary transmitter for data transfer between a stator fixed to the frame and a rotor fixed to the spindle is provided. The invention is characterized in that the machine spindle comprises a plurality of function modules on the spindle side as well as a line system forming a component of a spindle bus to which the function modules on the spindle side are connected to form subscriber stations of the spindle bus and wherein the spindle bus communicates via the rotary transmission path with a field bus fixed to the frame. |
