Abstract: A cutting insert (1) comprises: a first end surface (2) and a second end surface (3) which are opposed to each other; a peripheral side surface (4) which extends so as to connect the first end surface (2) and the second end surface (3); a first cutting edge (5a) which is arranged in an intersecting edge between the first end surface (2) and the peripheral side surface (4); and a second cutting edge (5b) which is arranged in an intersecting edge between the second end surface (3) and the peripheral side surface (4). The peripheral side surface (4) includes a first flank (4a1) which is connected to the first cutting edge (5a) and an intermediate peripheral side surface portion (4b) which is arranged closer to the second end surface (3) than the first flank (4a1). The first flank (4a1) extends in a direction perpendicular to the first end surface (2). The intermediate peripheral side surface portion (4b) protrudes outward from the first flank (4a1).

Abstract: A double-sided, indexable cutting insert for a milling cutter includes a first surface, a second surface, and side surfaces. Major cutting edges are defined at an intersection between the first and second surfaces and side surfaces. Minor cutting edges and ramping cutting edges are defined at the intersection between the first and second surfaces and side surfaces. The cutting insert is mounted in a milling cutter having a bottom seating surface formed at an angle with respect to a central, rotational axis of the milling cutter, which provides superior performance for both milling and ramping cutting operations.

Abstract: A prismatic and cylindrical cutting insert for long edge rotary milling applications has multiple indexable cutting edges ranging from four to six or even more depending on the actual milling applications. Each cutting edge of a prismatic or cylindrical cutting insert provides a positive cutting geometry and is equivalent to an indexable cutting edge of a traditional single-sided parallelogram-shaped cutting insert having two indexable cutting edges (often referred as A-Style insert). The prismatic and cylindrical (including tapered or conical) cutting insert may be used for machining a wide range of materials including difficult-to-machine materials, cast-iron and alloys, aluminum and alloys, carbon steels, and fiber reinforced composites.

Abstract: A cutting insert has polygonal first and second end surfaces which are connected by a peripheral side surface, each end surface defining first and second end planes, respectively. The peripheral side surface has first peripheral side portions alternated in the circumferential direction with second peripheral side portions. The first peripheral side portions are inverse copies of the second peripheral side portions. Each peripheral side portion includes first and second sub-faces which form different angles with the first and second end planes. The first and second sub-faces intersect one another between the first and second end planes to form a line which is parallel to the first and second end planes.

Abstract: A double-sided cutting insert for milling, in particular for face milling, includes first and second cutting edges each having alternately disposed main lips and secondary lips which each extend between active and passive cutting corners. Each main lip, starting from a first distance from a reference plane at an active cutting corner, extends in a manner dropping monotonously to a smaller, second distance from the reference plane at a passive cutting corner. That end of a secondary lip that adjoins the active cutting corner is in each case at a greater distance from the reference plane than the other end of the secondary lip that is remote from the active cutting corner. A circumferential side surface has, immediately adjacent the secondary lips, in each case planar secondary flanks and each secondary lip is formed at least regionally in a convex manner in plan view of the associated secondary flank.

Abstract: Provided is a cutting tool such that the progress of wear is delayed and that wear resistance is excellent. This cutting tool is configured in such a way that multiple cover layers (7, 8, 9, 10, 11, 12, 14) are formed on the surface of a substrate (6); that the outermost layer (14), which is one of the cover layers, comprises a Ti(CxNyOz)a (x+y+z=1, 0≦x≦0.6, 0≦y≦0≦0.6, 0.2≦z≦0.8, 1.0≦a≦1.7) layer; and that the thickness of that portion of the outermost layer (14) which is located in the center section (3a) of a flank surface is smaller than the surface roughness (Ra) of the outermost layer (14). The outermost layer (14) comes into contact with an article to be cut, leading to a coating being generated, with the result that the progress of wear is restricted.
