Abstract: A boring bar for a non-rotating boring tool includes an elongated main part configured for attachment to a support structure of a metal cutting machine. A front part is arranged to carry a tool part provided with a cutting element and at least one damping module, which is arranged between a front end of the main part and a rear end of the front part and which is provided with an electrically controlled vibration actuator configured to generate vibratory forces for active vibration damping of the boring bar. 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.

Abstract: A non-rotating boring tool for internal turning includes a boring bar having an elongated body, a cutting element with a rake side, a relief surface and a cutting edge, and an electrically controlled vibration actuator for active vibration damping of the boring bar. Moreover, when seen in a cross-sectional plane that is perpendicular to a longitudinal axis of the elongated body and intersecting the cutting edge in a radially outermost point, straight and imaginary first and second reference lines intersect the cutting edge in the radially outermost point with the first reference line extending at an angle of 6° to the relief surface on the outside of the cutting element, and the second reference line extending between the rake side and the relief surface at an angle of 10-40° to the first reference line. The actuator is arranged with its working axis extending in parallel with the second reference line.

Abstract: An adjustable cartridge for a boring bar includes a support structure including a surface for abutment with a peripheral area of a boring bar. A load-bearing structure mounts a cutting insert assembled to be movable in a first direction on the support structure. An adjustment mechanism is arranged to adjust the position of the load-bearing structure in relation to the support structure. The adjustment mechanism includes at least a first elastic means arranged to exert force against a first surface of the load-bearing structure, and an adjustment part disposed between the support structure and a second surface of the load-bearing structure and arranged to contact and to be movable in a second direction relative to the support structure and the load-bearing structure. The adjustment part has a surface that forms an acute angle with the second direction and is disposed in contact with a second surface of the load-bearing structure.

Abstract: A vibration damping toolholder for a metal cutting tool, the toolholder including a holder body provided with an internal cavity, which extends inside the holder body along the longitudinal axis, and which has a first cavity end at a first holder body end. The damping toolholder further includes a tuning mass, which is movably arranged inside the cavity and extends along the longitudinal axis, and which has a first tuning mass end at the first holder body end. The damping toolholder also includes a damping medium, which surrounds the tuning mass inside the cavity, and a single primary spring element, which is positioned inside the cavity. An outer spring element end is immovably fixed to a first cavity end at the longitudinal axis, and an inner spring element end is immovably fixed to the first tuning mass end at the longitudinal axis.

Abstract: A boring head for fixing a boring tool includes a main body mounted to a rotatable tool holder, a piston being received within and movable with respect to the main body in a radial direction, wherein a circumferential surface of the piston has a flat face parallel with the radial direction, and a combined orientation and fixation device for orienting and fixing the piston with respect to the main body. The combined orientation and fixation device includes a blind sleeve mounted in the main body, a flexible end wall of the blind sleeve facing the flat face of the piston, and a tightening screw configured for engagement with the blind sleeve so that the flexible end wall presses against the flat face when the tightening screw is tightened to press the piston against the main body and to simultaneously orient and fix the piston with respect to the main body.

Abstract: A boring bar for a non-rotating boring tool includes an elongated body configured for attachment to a support structure of a metal cutting machine and arranged to carry a tool part provided with a cutting element. At least two electrically controlled vibration actuators are arranged for active vibration damping of the boring bar. Each actuator includes a moveably arranged damping mass configured to generate vibratory forces in parallel with a working axis of the actuator that is perpendicular to a center axis of the damping mass. Each actuator is a single-axis actuator having one single working axis, wherein the actuators are arranged with their working axes angularly offset from each other. The actuators are arranged in a longitudinal series in the elongated body with the center axis of the damping mass of each actuator coinciding with a longitudinal axis of the elongated body.
