摘要:
A cutting tool includes a basic body and a cutting body that is fixable to the basic body via a male/female coupling. The coupling includes male-like fingers and female-like seats, which are delimited between elastically resilient projections. Each finger includes two converging wedge surfaces, which are pressable against a pair of diverging support surfaces of two adjacent projections. The axial angle of convergence of the two wedge surfaces of an individual finger differ from the angle of divergence of the two co-operating support surfaces of the projections, as long as the fingers are not loaded against the projections. In such a way, the removal of the cutting body from the basic body is facilitated.

A tool for chip-removing machining includes a holder on which in indexible cutting insert is mounted. The holder includes a first base surface on which a plurality of male parts are disposed to define an insert seat. The insert includes generally parallel second and third base surfaces, each having a plurality of female parts disposed therein. The insert is invertible such that the female parts of one of the second and third base surfaces receive respective male parts of the holder. A fastener secures the insert on the seat, with the male parts tightly fitted in the female parts. The male parts are flexible relative to the first base surface to ensure a firm abutment of the male parts with surfaces of respective female parts.

A cutting insert having a front cutting edge and a connecting surface including male- and/or female-like engagement portions, in order to rigidly secure the cutting insert, a geometrically predetermined reference locus serving as a force-application spot for the clamping of the cutting insert. Simultaneously active engagement portions are of only two types—a first, elongate engagement portion, which is located between the front cutting edge and the reference locus, and a second, elongate engagement means, which is oriented at an angle to the first engagement portion and situated at a greater distance from the front cutting edge than the reference locus. In such a way, it is guaranteed that a tightening force always is applied to the cutting insert in a substantially triangular area, which is defined by the free ends of the engagement portions. Furthermore, a tool for chip removing machining, as well as an attachment, e.g., a shim plate, for such tools is provided.

Tool for chip removing machining includes a basic body having an insert seat, and an indexable cutting insert fixed in the seat. The insert includes two cutting edges and at least two heads spaced-apart via an intermediate part and individually include a front portion having at least one cutting edge and a rear portion along which a pair of side contact surfaces are formed. The insert seat includes a front cavity including a pair of side support surfaces against which side contact surfaces of the cutting insert are pressed. The basic body is formed integrally of steel material and the seat is countersunk in the basic body so side support surfaces are integrated in the steel material. The cutting insert is formed integrally from a second, hard-wearing material having at least the same hardness as cemented carbide, the side contact surfaces of the insert being integrated in the second material.

A cutting tool includes two parts releasably interconnectable via serration surfaces which are mechanically engageable in each other. At least one of the parts is composed of a first body and a supplemental body on which the serration surface of the one part is formed, and which via a permanent joint is stiffly united to the first body. The permanent joint can be established by laser-welding a shim disposed between the first body and the supplemental body.

The invention relates to a cutting tool including a basic body and a cutting insert detachably connected to the basic body via an interface, which includes a pair of co-operating connecting surfaces in which engagement means are included, which may be in the form of knobs and seatings. A knob and a co-operating seating have a rotationally symmetrical, conical shape to prevent translation of the cutting insert in the plane of the interface. Another knob ensures that the cutting insert cannot be rotated in relation to the conical knob. Simultaneously, ample bearing surfaces abut against co-operating support surfaces in a connecting surface. In such a way, the cutting insert is fixed in a stable, non-overdetermined position in the basic body. Furthermore, the invention relates to a cutting insert as such.
