A rotary table (1) for work centres comprises a base body (2), a workpiece holder plate (4) rotatable with respect to the base body (2), means (5) for rotationally operating the workpiece holder plate (4), actuator means (7) for actuating locking means (6), control means (15) for controlling the operating means (5), communication means (17) able to exchange signals with corresponding communication means (17') and with the control means (15), and electrical power supply means (12) for powering the control means (15) and the communication means (17). The table (1) also comprises an energy source (10), mounted on-board the table (1), for actuating the actuator means (7) of the locking means (6). The means (5) for rotational operation of the workpiece holder plate (4) are electric motor means able to be powered by the electric power supply means (12). |
