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.
