NON-ROTATING BORING TOOL FOR INTERNAL TURNING AND A BORING ARRANGEMENT COMPRISING SUCH A BORING TOOL

A non-rotating boring tool for internal turning comprising:- a boring bar (2) comprising an elongated body (6);- a cutting element (5) with a rake side (30), a relief surface (32) and a cutting edge (33); and- an electrically controlled vibration actuator (8) for active vibration damping of the boring bar.When seen in a cross-sectional plane that is perpendicular to a longitudinal axis (7) of the elongated body and intersects the cutting edge in a radially outermost point (39), straight and imaginary first and second reference lines L1, L2 intersect the cutting edge in the radially outermost point with:* the first reference line L1 extending at an angle of 6° to the relief surface (32) on the outside of the cutting element, and* the second reference line L2 extending between the rake side (30) and the relief surface (32) at an angle of 10-40° to the first reference line L1.Said actuator is arranged with its working axis (10) extending in parallel with the second reference line L2.
