摘要： A milling cutter tool including a basic body and a replaceable cutting body. The basic body includes an envelope surface and two opposite ends, between which a geometrical center axis (C1) extends around which the basic body is rotated in a predetermined direction of rotation. The replaceable cutting body includes a pair of opposite main surfaces, one of which in a mounted state forms an underside and the other one of which forms an upperside, a pair of opposite sides, and a pair of opposite end surfaces. The cutting body further includes a set of teeth which are situated with a uniform partition along one of the pair of opposite sides of the cutting body, each of the teeth including a chip surface formed adjacent to a cutting edge from which the tooth extends between a pair of flanks along a length extension which is orientated at an angle to the underside of the cutting body. The cutting body is fixed in a pocket opening in the envelope surface of the basic body and having a support surface facing the forward direction of the direction of rotation of the basic body, against which the underside of the cutting body is mounted. The support surface of the pocket, and the underside of the cutting body, are tipped at a negative axial angle (γ) of at least 0.5° in relation to the center axis (C1) of the basic body such that the teeth of the cutting body are located along a common, phantom helical line (X), which is concentric with the center axis (C1) of the basic body and has an even pitch which corresponds to the partition between the teeth.

摘要： A cutting insert for a gear milling tool comprises an under side, an opposite upper side that forms a chip surface and is parallel to an extension plane (p), a circumferential edge side that connects the upper side and the under side. A centre axis (A) extends through the under side. A symmetry line (S) is perpendicular to the centre axis. A first cutting edge comprises a primary main cutting edge, a secondary main cutting edge—which are symmetrical in respect of the symmetry line—and a transverse end cutting edge between the primary and the secondary main cutting edge. A normal to the extension plane (p) forms an acute clearance angle with the edge side at least along the first cutting edge so that the cutting insert obtains a positive cutting geometry.

摘要： A hobbing tool made of cermet composed of 70 to 97 percent by weight of hard phase and a binder phase. The hard phase is made of a composite carbonitride of transition metals including titanium and tungsten, and at least one other element. The binder phase contains nickel and/or cobalt and inevitable impurities. The ratio between nitride atoms and carbon atoms and the ratio between titanium atoms and the atoms of transition metals other than titanium in the hard phase should be within specific ranges. The cermet having the above composition has an increased toughness and an excellent resistance to heat and wear and is difficult to weld.

摘要： A skiving cutter includes a cutting edge portion in which a tooth trace extends in a direction inclined with respect to an axis of a base. The cutting edge portion is segmented into a plurality of segmented cutting edges by cutting edge grooves extending in a direction intersecting the tooth trace. One of the plurality of segmented cutting edges forms a reference cutting edge. Among the plurality of segmented cutting edges constituting the cutting edge portion, the reference cutting edge has the largest axis-cutting edge distance which is a distance from the axis to the outer circumferential cutting edge of the segmented cutting edge, and the remaining one or more segmented cutting edges have gradually smaller axis-cutting edge distances as a distance from the reference cutting edge to each of the remaining cutting edges increases. A helix angle is different according to positions of the plurality of segmented cutting edges.
