Boring bar and a non-rotating boring tool and a boring arrangement comprising such a boring bar

A boring bar for a non-rotating boring tool, the boring bar comprising:

• an elongated main part configured for attachment to a support structure of a metal cutting machine, the main part having a rear end and an opposite front end;
• a front part having a rear end facing the front end of the main part and an opposite front end, the front end of the front part being arranged to carry a tool part provided with a cutting element;
• and
• at least one damping module arranged between the front end of the main part and the rear end of the front part, wherein the at least one damping module has a rear end facing the main part, an opposite front end facing the front part and a centre axis extending between the rear end and the front end of the damping module, wherein the at least one damping module is provided with an electrically controlled vibration actuator for active vibration damping of the boring bar, wherein this actuator is configured to generate vibratory forces, wherein the front part is connected to the main part via the at least one damping module, wherein the main part, the front part and the at least one damping module together form an elongated body, and wherein the at least one damping module constitutes a length section of the elongated body.
