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.
A milling tool arranged for face milling of a work piece, said milling tool comprising:
A kit of replaceable cutting inserts configured to be arranged successively along a periphery of a tool body of a milling tool for face milling, said milling tool including a tool body having a central rotation axis defining an axial direction, said periphery including an envelope surface extending along the axial direction and a front surface extending along a radial direction, each of said cutting inserts including a rake face, a clearance surface, and a main cutting edge provided for a roughing operation, wherein said main cutting edge is formed between said rake face and said clearance surface and extends along the axial direction and the envelope surface of the tool body, when arranged on the tool body, and wherein the cutting inserts of a subset of the cutting inserts includes at least two cutting inserts including a plurality of secondary cutting edges provided for a finishing operation, wherein said plurality of secondary cutting edges are formed between said rake face and said clearance surface along the front surface of the tool body, and wherein each of said plurality of secondary cutting edges includes at least a first secondary cutting edge, a second secondary cutting edge, and a third secondary cutting edge, wherein said first and third secondary cutting edges, when arranged on the tool body, extend in a direction perpendicular to said axial direction and said second secondary cutting edges extend between said first and said third secondary cutting edge, wherein, when arranged on the tool body, the main cutting edges of the cutting inserts are situated at a same radial position along the envelope surface of the tool body, said first secondary cutting edges being situated at a same axial position and wherein, when arranged on the tool body, a first end point of each of said second secondary cutting edges successively progresses radially inward relative to a succeeding cutting insert of said subset, and a second end point of each of said second secondary cutting edges successively progresses radially inward and axially outward from the front surface along a periphery of said front surface of said tool body relative to the succeeding cutting insert of said subset, such that the second secondary cutting edge of the succeeding cutting insert has a greater length and is situated closer to the central rotation axis of said tool body than the second secondary cutting edge of a preceding cutting insert along said front surface of the tool body.
