摘要： A milling insert for a side and face milling tool includes an upper side defining an upper extension plane, a lower side defining a lower extension plane, and a side surface extending between the upper and the lower sides around a periphery of the insert that includes a main radial clearance surface, two opposite axial clearance surfaces and two corner clearance surfaces. At least one cutting edge is formed in a transition between the upper and the side surfaces, wherein each cutting edge includes a main cutting edge extending above the main radial clearance surface and two corner cutting edges extending above the corner clearance surfaces on opposite sides of the main cutting edge. The main cutting edge slopes downward toward a midpoint of the main cutting edge and the main cutting edge and the main radial clearance surface slope outward from the corner cutting edges toward the midpoint.

摘要： A connection tube (1) for connecting two tubes (8, 9) of different alloys, wherein the connection tube has a central through-hole extending along a longitudinal axis and comprises a first end portion (2) of a first alloy, a second end portion (3) of a second alloy, and a middle portion (4) which is at least partly double-layered with said second alloy forming an annular inner layer and said first alloy forming an annular outer layer, wherein a metallic bond has been formed between said layers. The inner and outer layers are mechanically interlocked by means of at least one helically extending thread formed in an interface between said layers. The connection tube is manufactured from a base component and an outer component threaded onto the base component to form a work piece, which is hot worked to form a metallic bond.

摘要： A method of making a cutting tool includes providing a first sintered cemented carbide body of a WC, a metallic binder phase and eta phase and wherein the substoichiometric carbon content in the cemented carbide is between −0.30 to −0.16 wt %. The first sintered cemented carbide body is subjected to a heat treatment at a temperature of between 500 to 830° C. for a time between 1 to 24 h. A cutting tool made according to the above method having an increased resistance against comb cracks is also provided.

摘要： A cutting tool having an elongate cutting head provided with a plurality of teeth and flutes in which a plurality of cooling grooves are recessed at a land region of each tooth between a cutting edge and a trailing edge. The grooves at the land do not extend to and are physically separated from the cutting edge to provide a tool optimized for cutting via radially consistent cutting edges and the promotion of heat exchange and dissipation from the rearward side/region of the teeth.

摘要： A blade portion for a grooving tool includes opposite first and second surfaces, a blade width thereof being defined as a shortest distance between the first and second surfaces, opposite third and fourth surfaces, and a fifth surface and an opposite blade portion end. The blade width is constant or substantially constant from the fifth surface up to the blade portion end. An insert seat separating the third surface and the fifth surface is arranged to receive an insert having a main cutting edge, an associated rake face, and an associated main clearance surface. The main cutting edge defines an insert width being greater than the blade width. A shortest distance from the fifth surface to the opposite blade portion end is greater than a shortest distance from the third surface to the fourth surface.
