Abstract
A milling tool includes a milling body and a plurality of cutting inserts. The milling body has fastening devices to hold the cutting inserts in a plurality of respective insert pockets each having at least one base surface. Each of the cutting inserts has at least one cutting edge. The tool has a rotational axis and a rotational direction, as well as a feed direction and an end surface. The milling tool is provided to cut a work piece substantially in an axial direction of the tool, which is substantially perpendicular to the feed direction.
Claims4
A milling body for a milling tool, the milling body defining an axis of rotation, and a front axial end surface;
- the body including circumferentially spaced pockets configured to receive cutting inserts;
- each pocket comprising at least one base surface;
- wherein the pockets are arranged in a plurality of segments, the segments arranged successively in a first circumferential direction of the body, each segment comprising more than two circumferentially successive pockets and including a leading pocket and a last trailing pocket with reference to the direction of rotation, the insert of each segment becoming disposed gradually radially inwardly in the circumferential direction of the body and gradually axially forwardly in the first circumferential direction of the body, the leading pocket of each segment being disposed adjacent the last trailing pocket of another segment, the leading pockets of the respective segments having substantially the same axial and radial positions on the body.
