Abstract: A face milling tool includes a tool body having an axial front end surface with several seats. Each seat has support surfaces for rotationally locking and supporting a tangential cutting insert in the seat. One of the support surfaces is a flat axial support surface for supporting the tangential cutting insert in an axial direction defined by the central rotation axis. The flat axial support surface extends perpendicular to the central rotation axis and is situated axially foremost in the seat. A side wall of each seat is formed out of round side support surfaces. Each tangential cutting insert includes an axial back side with a flat axial contact surface abutting the flat axial support surface and a projecting member extending axially from the flat axial contact surface and having a circumferential side surface forming out of round side contact surfaces abutting the out of round side support surfaces.

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: 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.
