ABSTRACT:
A rotating body, for example a chuck (10) comprises a sensor (56), a signal processing unit with amplifier and a plurality of transmitting diodes (14) and receiving diodes (16) peripherally spaced in a radial plane, in which also a stationary transceiving station (18) is arranged. The sensor (56) detects special working conditions of a tool clamped in the chuck (10). Signals of sensor (56) are fed to the signal processing unit. Sense commands transmitted from the transceiving station (18) via receiving diodes (16) are processed in the processing unit during rotation of the chuck (10) and corresponding working condition signals are transmitted from the transmitting diodes (14) back to the transceiving station (18).
