Abstract
An electrospindle includes a motor for moving a tool and a motor shaft for transmitting motion from the motor to the tool. The electrospindle has a gripping head of the tool and a coupling of the tool to the motor shaft, and the gripping head includes two flanges, between which a portion of the tool and at least one thrust nut of a first flange can be interposed toward a counterflange, so as to hold the tool in position. The electrospindle further includes an insert coupled by screwing to the free end of the motor shaft, the thrust nut being coupled on an end portion of the insert.
