摘要： A turning insert includes a top surface, an opposite bottom surface, side surfaces connecting the top surface and the bottom surface and two opposite nose portions. Each nose portion includes a convex nose cutting edge, a first cutting edge and a second cutting edge. The convex nose cutting edge connects the first and second cutting edges. A bisector extends equidistantly from the first and second cutting edges. In a top view the first and second cutting edges on the same nose portion form a nose angle (α) of 70-85° relative to each other. Each nose portion includes a third convex cutting edge adjacent to the first cutting edge and a fourth cutting edge adjacent to the third cutting edge. In a top view the fourth cutting edge forms an angle (β) of 0-34° relative to the bisector.

摘要： 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.

摘要： A cutting insert comprises a rake face, a plurality of flank faces including clearance faces having a positive clearance angle. A cutting edge is formed at an intersection between the rake faces and the flank face and a convex wiper cutting edge formed on the cutting edge. A method for forming the cutting insert comprises the steps of placing a powdered material into a die and pressing the powdered material in the die to achieve a form having a convex portion on the rake face and at least one substantially flat clearance face having a positive clearance angle. Next, the form is removed from the die and sintered.

摘要： A cutting insert includes opposing forward and rear surfaces and a peripheral surface extending therebetween. The peripheral surface includes opposing side surfaces and opposing upper and lower surfaces. The upper surface and the forward surface intersect to form a main cutting edge having an associated relief surface that extends therefrom in the forward surface. One of the side surfaces comprises an insert side abutment surface. The rear surface comprises an insert rear abutment surface. The lower surface comprises an insert lower abutment surface. The insert rear and insert lower abutment surfaces form an obtuse abutment angle with respect to each other. In a side view along a side axis, a relief surface line tangent to the relief surface intersects the insert lower abutment surface.

摘要： A cutting insert includes a rake face extending along a cutting edge and a rising wall surface extending so as to form a recess along the cutting edge together with the rake face. The rake face is formed to have a positive rake angle, and includes a first rake face and a second rake face arranged in order in a direction in which a distance from the cutting edge increases. The second rake face is larger than the first rake face in rake angle.

摘要： 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.

摘要： A turning tool includes a turning insert and a tool body. The turning insert has opposite facing top and bottom surfaces connected by a circumferential side surface. The turning tool has a pocket arranged for receiving the turning insert. The pocket includes a bottom support surface and first and second pocket side surfaces, the first and second pocket side surfaces forming an acute angle. The first pocket side surface includes first and second side support surfaces and the second pocket side surface includes third and fourth side support surfaces. The first recess is formed between the first and second side support surfaces and the second recess is formed between the third and fourth side support surfaces.

摘要： A cutting insert according to an aspect includes a top surface and a side surface. At least a part of a ridge line where the top surface and the side surface intersects is a cutting edge. The cutting edge includes a first portion located at a corner portion, a second portion adjacent to the first portion, a third portion close to the second portion, a fourth portion close to the third portion, and a fifth portion adjacent to the fourth portion. When viewed from directly above, a curvature radius of the second portion is less than a curvature radius of the first portion, a curvature radius of the third portion is greater than the curvature radius of the first portion, and a curvature radius of the fourth portion is less than the curvature radius of the third portion.
