MACHINING SYSTEM COMPRISING A TOOL HOLDER CAPABLE OF INTEGRATING SENSORS AND/OR ACTUATORS IN A ROTATING REFERENCE FRAME

The invention relates to a machining system comprising an electric spindle (10) on which tool holders (PO1, PO2, PO3) can be mounted that are able to contain several types of actuator and/or sensor, and a data acquisition and control member for acquiring data from the sensors via at least one signal conditioning circuit (Acq_1 - Acq_4) and controlling the actuators via at least one power electronics circuit (EP_1, EP_2), the system being characterised in that it comprises a switching matrix (40) and a control module (31) capable of receiving unique identification information of the tool holder mounted on the electric spindle and of configuring a switching arrangement of the matrix in order to selectively connect respective power and data paths of the power electronics circuit and the conditioning circuit to the identified tool holder.
