摘要:
The present disclosure relates to a method for producing a metal cutting tool component, comprising the steps of producing a front module (70), the front module (70) comprising a main body (57) and a front module interface (63) at a rear end. This step comprises the steps of providing an intermediate element (58), comprising providing the front module interface (63) at a rear end and a build surface (52) at a front end thereof, and building, using an additive manufacturing process, the main body (57) on the build surface (52) of the intermediate element (58). The method further comprises the steps providing a rear module (68) comprising providing a coupling part (66) at a rear end and a rear module interface (65) at a front end, after producing the front module and providing the rear module (68), mounting the front module (70) on the rear module (68) by immovably connecting the front module interface (63) and the rear module interface (65), after the front module (70) has been mounted on the rear module (68), machining at least one surface of the main body (57), and heat treating the intermediate element (58) with the built main body (57), wherein at least the main body (57) is hardened. The present disclosure also relates to a metal cutting tool component.
摘要:
The present invention is directed to the formation of a chip breaker in a polycrystalline diamond or cubic boron nitride compact. An oversized compact blank having a surface and edges that establish it as oversized is provided. A chip breaker pattern is formed on the compact blank surface. Preferred means for forming the chip breaker pattern include use of a laser, a plunge EDM apparatus, or by ultrasonic abrading. Thereafter, the edges of the patterned oversized compact blank are finished to reduce the size of the blank. When plunge EDM apparatus fitted with a patterned plunger is used, the compact blank must be electrically conductive.

The invention relates to a cemented carbide insert intended for chip removing machining, in particular turning, which comprises an upper side (1), an under side (2), and a number of side surfaces extending between the same, as well as a cutting edge (3a, 3b), which includes a nose edge (5) and two main edges (4) converging toward the same and is included in an inset (14), which consists of a material that is harder than the cemented carbide, and which is countersunk in the surrounding cemented carbide and co-ground with the same. The inset (14) is arranged in a front, wedge-shaped head (7), which is delimited by one chip surface (71) and two clearance surfaces (72) running along the main edges (4), as well as transforms into a postjacent body part (8) via limiting surfaces (81, 82) situated inside imaginary planes in the extension of said chip and clearance surfaces (71, 72). By placing the inset in such a head, the requisite grinding is reduced to a minimum. In addition, the invention relates to a blank for the manufacture of cutting inserts of the kind in question.

Um Verschleißerscheinungen an der Freifläche der Messerplatte einer Reibahle zu vermeiden und um trotz der zu diesem Zweck erfolgten Beschichtung der Messerplatte.mit einem Hartstoff den Schneidkantenradius unter einer Größe von etwa 5 µm zu halten, weist die Messerplatte mindestens im Bereich ihrer Nebenschneide eine von Hartstoff befreite Spanfläche (3) auf.
