A turning insert arranged for longitudinal turning of metal work pieces includes a nose cutting edge that slopes from a trailing cutting edge in direction towards a leading cutting edge. A turning tool is also disclosed.

Turning insert

A set of cutting inserts includes a stem portion, a plurality of branch portions attached to and extending from the stem portion, and at least one cutting insert attached to each of the plurality of branch portions. The stem portion has a longitudinal axis extending between a top end of the stem portion and a bottom end of the stem portion and at least one of the top end of the stem portion is disposed along the longitudinal axis above uppermost portions of each cutting insert, and the bottom end of the stem portion is disposed along the longitudinal axis below lowermost portions of each cutting insert. Also, methods for manufacturing a set of cutting inserts are disclosed.

A grooving blade for chip removing machining includes a cutting insert pocket and a damping arrangement fixed to the blade. The damping arrangement projects laterally with respect to at least one major surface of the blade. A grooving tool and a method of grooving a metallic workpiece are also disclosed.

Blade, tool and method of grooving a metallic workpiece

The present disclosure relates to a cutting tool for metal chip removing machining having at least one internal coolant channel for fluid having a flow direction. The at least one internal coolant channel having a length and including a plurality of grooves extending internally at least partially along the coolant channel.

Cutting tool and a nozzle with internally extending grooves

The present disclosure relates to a tool having a holder body, a cutting insert and a nozzle. The nozzle includes a single through hole for a fastening member. The nozzle has a forward end, a rear end and a bottom face. The through hole extends between the bottom face and an opposite top face. At least one internal coolant channel is provided in the nozzle and extends from a first opening to a second opening. The first opening connects to a coolant supply conduit in the holder body. The second opening serves as an exit for the coolant at the forward end. The at least one coolant channel and the first opening are spaced from the through hole.

A coupling and a blade for a cooling system in a cutting tool includes a first member including a shank having a first end and a second end. The first end of the shank defines a first end of the first member, and a head of the first member disposed at the second end of the shank and a top of the head of the first member defines a second end of the first member. The head of the first member is frustoconical and the first member includes a longitudinal passage in the shank. A radial opening in the head of the first member is in fluid communication with the longitudinal passage.

The present invention relates to a cutting insert for chip removing machining. The cutting insert has a substantially circular cutting edge formed at a transition between an upper side and an edge surface of the cutting insert. The upper side includes a chip surface including at least one chip breaker portion and the edge surface includes a clearance surface having an arrangement for indexing the cutting insert. The chip breaker portion is provided at varying distance from the associated cutting edge. The arrangement is provided in a position relative to a reference line or axis of the tool in order to orient the chip breaker portion in the chip surface to a desired position.

Indexable cutting insert with chip breaker

An indexable turning insert includes two opposing larges sides formed by a support center part and a plurality of cutting parts projecting outwardly therefrom, each having a cutting edge extending between the sides and being spaced apart around the outer perimeter of the center part for indexing, has four the cutting parts. Each cutting part has a clearance side extending on one of the sides of the insert from the cutting edge of the cutting part towards the center part while making clearance angles in two dimensions with respect to the cutting edge, and the cutting edge of each cutting part makes an angle being below 90&#xb0; by less than the clearance angles with the other of the sides of the insert.

Indexable turning insert and a cutting tool comprising such an insert

A cutting insert for turning includes a polygonal body of a hard, wear-resistant material, which has an upper surface and a lower surface, and a plurality of edge surfaces uniting the surfaces. At least one rounded cutting corner, provided with a nose-cutting edge, is formed at a nose portion at the area of the intersection area of two edge surfaces. The cutting corner defines a bisector. At least one recess is arranged in a support surface of the upper surface at a distance from the nose-cutting edge. The recess has a general extension toward the nose portion. Each recess is elongate and has successively increasing depth toward the nose portion.

A negative insert for cutting machining has a top side, a clearance side perpendicular thereto and a cutting edge in a region interconnecting these sides and extending substantially in parallel with these sides. The insert has further a flat or rounded chamfer connecting the cutting edge to the clearance side on at least one lateral side of the insert in the region of a corner thereof. The chamfer makes an angle of 1&#xb0;-15&#xb0; with the clearance side for enabling application of the chamfer substantially tangentially to a work piece to be machined for bearing of the insert in two dimensions against the work piece during cutting machining operation carried out by the insert.

Machine tool

A cutting insert includes a polygonal body of a hard, wear-resistant material, which has an upper surface and a lower surface, and a plurality of edge surfaces uniting said surfaces. At least one chip-breaker arrangement is provided in at least one of the lower and upper surfaces. At least one rounded cutting corner, provided with a nose-cutting edge, is formed at a nose portion at the area of the intersection area of two edge surfaces. The cutting corner defines a bisector. The chip-breaker arrangement includes two elongate chip-breaker segments having an opening provided therebetween intended to give room for a cooling jet directed toward the opening.

Cutting insert for metal chip removal

The present invention relates to a cutting insert, a cutting tool for chip removing machining, a shim as well as a method for mounting a cutting insert. The cutting tool includes a holder equipped with at least one insert pocket including a base surface, at least one circular shim including opposite first and second surfaces, and at least one cutting insert, which includes a circular cutting edge formed at a transition between an upper side and an edge surface of the cutting insert. The upper side includes a chip surface comprising at least one chip breaker portion and the edge surface includes a clearance surface. The shim is provided between the base surface of the insert pocket and the cutting insert. The cutting tool includes a clamping arrangement for holding its parts together. The chip breaker portion is provided at a varying distance from the associated cutting edge. The shim and the cutting insert include at least one pair of cooperating projection and recess for indexing of the cutting insert. The pair of cooperating projection and recess is provided to be positioned in a position relative to a reference line or axis of the tool in order to orient the chip breaker portion in the chip surface to a desired relative position. The number of chip breaker portions is a multiple of the number of projections or recesses.
