Abstract: A cable saw for cutting a workpiece includes a circulating saw cable, a guide device, and a cable storage device and cable tensioning device. The saw cable is driven by a drive and includes a sawing section. The guide device is arranged to move the sawing section along a cutting direction for cutting engagement with the workpiece. The guide device is arranged to allow several movement directions including the cutting direction and at least one lengthening or shortening of the sawing section. The cable storage device and cable tensioning device is arranged for storing, releasing and/or tensioning the saw cable when changing a position and/or length of the sawing section. The guide device includes a lever gear with a pivot lever rotatably hinged to a base holder. The lever gear is arranged to convert a rotational movement of the pivot lever into a movement of deflection rollers—which form the sawing section therebetween—to lengthen and/or shorten the sawing section.

Abstract: A cemented carbide insert, including an upper side, an under side, a plurality of side surfaces extending between the upper side and the underside, and an inset including a cutting edge. The cutting edge includes a nose edge and two main edges converging toward the nose edge. The inset is formed of a material that is harder than the cemented carbide, and is countersunk in the surrounding cemented carbide and co-ground with the surrounding cemented carbide. The inset is arranged in a front, wedge-shaped head delimited by one chip surface and two clearance surfaces running along the main edges. The inset transforms into an adjacent body part via limiting surfaces situated inside imaginary planes in the extension of the chip surface and the clearance surfaces.

Abstract: A cutting insert kit, including a base part formed of a brittle and wear-resistant material, and a plurality of cutting insert blanks integrally formed with the base part, which are separable one by one from the base part via indications of fracture. Each insert blank includes a front end portion, a rear end portion, an upper side, an under side, and at least one cutting edge in the front end portion formed between a clearance surface and one of the upper and under sides. The base part is common to all cutting insert blanks and to which each cutting insert blank is united to the base part via an indication of fracture in the form of a weakened connection member between the base part and the rear end portion of the cutting insert blank.

Abstract: 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.

Abstract: A tool for chip removing machining, including a basic body having an insert seat, and an indexable cutting insert fixed in the seat. The insert includes an upperside, an underside, a pair of side contact surfaces, two cutting edges that individually extend along a chip surface included in one of the upperside and underside, at least two heads that are spaced-apart via an intermediate part and individually include a front portion having at least one cutting edge and a rear portion along which the pair of side contact surfaces are formed. The insert seat of the basic body includes a central hollow space, and a front cavity and at least one rear cavity in which the heads of the cutting insert are housed, the front cavity including a pair of side support surfaces against which the pair of side contact surfaces of the cutting insert are pressed when a tightening element pulls the head rearward toward the side support surfaces. The basic body is solid by being formed integrally of steel material.

Abstract: 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.

Abstract: An indexable turning insert, which has a symmetrical, preferably rotationally symmetrical basic shape, that is determined by a clearance surface extending between a top side and an underside, and which includes a cutting edge as well as a coupling device located to the underside. The coupling device comprises at least two, preferably three, suitably equiangularly spaced-apart engagement members, preferably in the form of ridges, emanating radially from a center axis and having a pair of flanks that mutually form an obtuse angle. A turning tool and an attachment for the same is also disclosed.

Abstract: 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.
