Abstract (en)
This invention concerns a grinding system comprising a grinder (30) and an abrasive grinding wheel (1). The grinder (30) comprises an actuating arm (31) adapted to receive the grinding wheel (1), an actuator (33) coupled to the actuating arm (31) to rotatably drive or translate it along a driving axis, an electronic control unit (35) operatively coupled to the actuator (33) and a transceiver unit (39) coupled to the control unit (35) and adapted to transmit electromagnetic signals. The grinding wheel (1) is fixed to the actuating arm (31) of the grinder (30). The grinding wheel (1) comprises a body (10) which has at least one abrasive surface (13) intended to come into contact with a workpiece to be machined, and an electronic unit (20) coupled to the body (10). Furthermore, the transceiver unit (39) of the grinder (30) comprises a plurality of resonant circuits (391) arranged aligned along an axis parallel to the driving axis of the actuating arm (31), whereas the electronic unit (20) of the grinding wheel (1) comprises a further resonant circuit (271) having a resonance frequency equal to or close to the resonance frequency of the resonant circuits (391) of the transceiver unit (39).
