摘要： The invention concerns an indexable cutting insert (2) intended for chip removing machining and of the type that comprises a plurality of cutting tips (21) that protrude from a central core (20) and individually include a cutting edge (25), which is formed in a transition between an upper side serving as chip surface (26), and a clearance surface (33), which extends between the upper side and an under side. According to the invention, the cutting insert comprises six equally long cutting tips (21 a, 21 b, 21 c, 21 d, 21 e and 21 f) that are located in pairs along the co-ordinate axes (X, Y, Z) of a three-dimensional, orthogonal system of co-ordinates, the origin of which is situated in the core (20). By arranging the cutting tips (21 a, 21 b, 21 c, 21 d, 21 e and 21 f) in this way, the inactive cutting tips, which are situated behind an active cutting tip, can be contained within a limited volume and therefore be installed in tool basic bodies having tapering parts.
In addition, the invention relates to a tool equipped with the cutting insert according to the invention as well as a tool basic body as such.

摘要： A multi - grooving tool holder for holding cutting members (14) seated in a side-by- side formation in a clamping portion (16) of the holder. The clamping portion (16) includes an upper clamp (20) and a lower clamp (22) and an elastic member (58) is located in one of the upper and lower clamps. When cutting members (14) are assembled in the clamping portion(16), the elastic member (58) engages the cutting members and aligns each cutting member independently, by applying a force, and consequently a moment on the cutting members.

摘要： The invention relates to a cutting tool comprising a solid basic body (1) of steel and an indexable cutting insert (2), which is fixed in a seat (3) that is formed in the basic body and includes a bottom surface (30) and two side support surfaces (37) projecting from the same. The cutting insert (2) comprises an upperside (5), an underside (6), a pair of side contact surfaces (13), which are kept pressed against the side support surfaces (37) of the seat (3) by means of a tightening element (4) as well as at least two alternately usable cutting edges (11) that individually extend along a chip surface included in the upperside (5). The cutting insert (2) comprises at least two heads (8) that are spaced-apart via an intermediate part (15) and individually include a front portion having at least one cutting edge (11) as well as a rear portion along which the two side contact surfaces (13) are formed. By, on one hand, manufacturing the cutting insert (2) integrally from a material having at least the same hardness as cemented carbide and in such a way integrating the side contact surfaces in the hard material, and on the other hand, integrating the side support surfaces (37) of the seat directly in the steel material in the basic body (1), a meticulous location is obtained of the active cutting edge (11) of the cutting insert in relation to the fixing part of the basic body (1). In addition, the invention relates to an indexable cutting insert as well as a basic body of the tool.

摘要： A cutting tool assembly includes a cutting tool and an indexable cutting insert having an insert index axis. The cutting insert includes parallel insert first and second sides connected by an insert peripheral surface that extends peripherally around the cutting insert. At least one clamping hole opens out to one or both of the insert first and second sides, and at least a portion of the clamping hole is in a clamping region of the cutting insert. The insert peripheral surface includes cutting edges that are spaced-apart and extend from the insert first side to the insert second side. Along a width direction, which is perpendicular to the insert first and second sides, each of the cutting edges is wider than the cutting insert, at least at the cutting region of the cutting insert.

摘要： The present invention relates to an indexable cutting insert (20) comprising two opposing end surfaces (22) with a peripheral side surface (24) and a central axis (C) extending therebetween. The cutting insert (20) has four cutting portions (26a, 26b, 26c, 26d), four spaced apart abutment zones (28a, 28b, 28c, 28d), and mirror symmetry about mutually perpendicular first and second planes (P1, P2) containing the central axis (C). Each of the four cutting portions (26a, 26b, 26c, 26d) has a cutting edge (32a, 32b, 32c, 32d) formed by the intersection of a rake surface (34a, 34b, 34c, 34d) and a relief surface (36a, 36b, 36c, 36d), the four rake surfaces (34a, 34b, 34c, 34d) and the four relief surfaces (36a, 36b, 36c, 36d) located on the peripheral side surface (24). Each of the four abutment zones (28a, 28b, 28c, 28d) represents a distinct region of the peripheral side surface (24) capable of making clamping contact with a corresponding region of a mating component in at least one index position of the cutting insert (20). The peripheral side surface (24) includes two pairs of opposing side surfaces (38a, 38b), a first pair of opposing side surfaces (38a) mirror symmetrical about the first plane (P1), and a second pair of opposing side surfaces (38b) mirror symmetrical about the second plane (P2). The four cutting edges (32a, 32b, 32c, 32d) are formed at the intersections between the two pairs of opposing side surfaces (38a, 38b). The second pair of opposing side surfaces (38b) includes the four rake surfaces (34a, 34b, 34c, 34d) and the four abutment zones (28a, 28b, 28c, 28d). In a side view of the cutting insert (20), each of the four abutment zones (28a, 28b, 28c, 28d) forms a V-shape with an adjacent one of the four abutment zones (28d, 28c, 28b, 28a).

摘要： A threading insert is provided of a type that includes a mount portion and a plurality of arms radiating therefrom that each forms a pair of cutting edges, which is rugged, facilitates accurate positioning of the insert on the tool holder, encourages reliable breaking of cutting chips, and enables internal threading in a small diameter hole. One insert includes four arms (34-40, Fig. 3) radiating from a mount portion (24), with each arm having a radially outer edge (52) and a pair of opposite sides (54, 56), and forming a cutting edge (58, 60) at the interception of each side with an end of the outer edge. The mount portion has four flat locating surfaces (42-48) lying at the sides of an imaginary square, with each locating surface lying between a pair of arms and with there being an obtuse angle (D) between each locating surface and an adjacent side of an arm. The side of each arm extends only a short radial distance before intersecting a flat locating surface, which results in rapid breaking of chips and there being a considerable distance between a central hole in the insert and each locating surface to avoid insert breakage. Each arm outer edge subtends an angle of no more than about 30°.
