Abstract: An actuatable boring bar is configured to place a cutting insert cartridge received onto the boring bar in a cutting position when the centrifugal force generated by the rotation of the boring bar about the rotation axis reaches a centrifugal force threshold and in a non-cutting position when the centrifugal force generated by the rotation of the boring bar about the rotation axis is below the centrifugal force threshold. The boring bar is further configured so that the cutting insert cartridge can be set-up onto the boring bar in the cutting position.

Abstract: A milling tool for face milling includes a tool body and a plurality of cutting members arranged successively along a periphery of the tool body. Each cutting member includes a main cutting edge provided for a roughing operation and a subset having a first, a second and a third secondary cutting edge provided for a finishing operation. The first and third secondary cutting edges extend in a direction perpendicular to an axial direction and the second secondary cutting edge extends between the first and third secondary cutting edge. The main cutting edges are situated at the same radial position and the first secondary cutting edges are situated at the same axial position. A first end point of the second secondary cutting edges successively progress radially inward and a second end point of the second secondary cutting edges successively progress radially inward and axially outward along the periphery of the tool body.

Abstract: A cutting tool has a tool body having at least one pocket, at least one cutting insert releasably fixed to the pocket and a fastening device for securing the insert in the pocket. The pocket has a raised portion) with a flat upper support face arranged to be received in a recess of the insert and support the insert by receiving a bottom surface of the recess bearing on the support face. A projecting member of the raised portion has delimiting walls designed to bear against border walls of the recess of an insert for establishing mutual contact therewith and prevent rotation of the insert in the pocket by receiving a rotational moment acting on the insert in an active chip-removing state of the tool.
