A system for moving a tool in a machine tool, comprising: a frame; a member movable relative to the frame along or about an axis of movement; a unit for transmission of the rotational motion operatively interposed between the frame and the movable member; a hydraulic stop unit operatively interposed between the frame and the movable member; a control unit associated with the transmission unit and the stop unit for controlling them; wherein the stop unit comprises: at least a first element rigidly connected to the frame and at least a second element rigidly connected to the movable member, a hydraulic actuation circuit associated with the first or the second element and configured for moving the first element towards and/or away from the second element, or vice versa, according to a command issued by the control unit, and wherein the control unit is configured for selectively controlling the hydraulic actuation circuit at a first pressure, in which it generates a first contact force between the first and the second element, or at a second pressure, in which it generates a second contact force between the first and the second element, greater than the first pressure; the second pressure being sufficient to stop the movement of the second element /107) with respect to the first element, characterised in that it comprises at least one vibration sensor designed to detect any vibrating motions of the tool and designed to send to the control unit a signal representing the vibrating motions; the control unit being: associated with the sensor for receiving the signal; configured for controlling the hydraulic actuation circuit in such a way as to bring it to the first pressure, defining the first configuration. a frame; a member movable relative to the frame along or about an axis of movement; a unit for transmission of the rotational motion operatively interposed between the frame and the movable member; a hydraulic stop unit operatively interposed between the frame and the movable member; a control unit associated with the transmission unit and the stop unit for controlling them; wherein the stop unit comprises: at least a first element rigidly connected to the frame and at least a second element rigidly connected to the movable member, a hydraulic actuation circuit associated with the first or the second element and configured for moving the first element towards and/or away from the second element, or vice versa, according to a command issued by the control unit, and wherein the control unit is configured for selectively controlling the hydraulic actuation circuit at a first pressure, in which it generates a first contact force between the first and the second element, or at a second pressure, in which it generates a second contact force between the first and the second element, greater than the first pressure; the second pressure being sufficient to stop the movement of the second element /107) with respect to the first element, characterised in that it comprises at least one vibration sensor designed to detect any vibrating motions of the tool and designed to send to the control unit a signal representing the vibrating motions; the control unit being: associated with the sensor for receiving the signal; configured for controlling the hydraulic actuation circuit in such a way as to bring it to the first pressure, defining the first configuration. at least a first element rigidly connected to the frame and at least a second element rigidly connected to the movable member, a hydraulic actuation circuit associated with the first or the second element and configured for moving the first element towards and/or away from the second element, or vice versa, according to a command issued by the control unit, and wherein the control unit is configured for selectively controlling the hydraulic actuation circuit at a first pressure, in which it generates a first contact force between the first and the second element, or at a second pressure, in which it generates a second contact force between the first and the second element, greater than the first pressure; the second pressure being sufficient to stop the movement of the second element /107) with respect to the first element, characterised in that it comprises at least one vibration sensor designed to detect any vibrating motions of the tool and designed to send to the control unit a signal representing the vibrating motions; the control unit being: associated with the sensor for receiving the signal; configured for controlling the hydraulic actuation circuit in such a way as to bring it to the first pressure, defining the first configuration. associated with the sensor for receiving the signal; configured for controlling the hydraulic actuation circuit in such a way as to bring it to the first pressure, defining the first configuration.
