摘要： Polygonal turning insert has a cutting edge including three part edges, a nose edge and two main edges, and chip-guiding flank surfaces for each part edge, a primary flank surface, and secondary flank surfaces. The primary flank surface is convexly arched and delimited by an arched lower boundary line, which has an apex point facing the nose edge and is situated along a bisector between the main edges, and includes two mirror-symmetrical arc part lines extending from the apex point to a pair of opposite end points situated along a reference line intersecting the bisector at a midpoint between the end points. The distance between the midpoint and the individual end points is greater than that between the midpoint and the apex point. An angle of inclination of the primary flank surface decreases from a greatest value in a bisector section to a smallest value in a reference line section.

摘要： A cutting insert, intended for chip removing machining, includes a body delimited by two opposite, first and second surfaces, which in the operative state of the cutting insert form an actively chip removing top surface and a bottom surface, respectively. The insert also includes at least one side surface, serving as a flank surface, which extends between the first and second surfaces. A cutting edge is formed between the flank surface and at least one of said first and second surfaces, in which a segment is included, which has the purpose of smoothening and facing the machined surface of the workpiece. The smoothening edge segment is divided into at least three different part edge segments, a first of which forms a tangent point and is surrounded by two part edge segments having longer radii (R22, R23) than the first edge part segment.

摘要： A double-sided, indexable turning insert having a polygonal basic shape, including at least three corners, and an upper side and an under side, in which first and second opposite, plane support surfaces are included, The plane support surfaces are delimited inside outer contour lines, and parallel to each other and to a neutral plane (NP) situated halfway between the plane support surfaces. A plurality of cutting edges are along the upper side and the under side, each one of which includes a nose edge and two main edges converging toward the nose edge, all nose edges along the individual upper or under side being situated in a common reference plane (RP) that is depressed in relation to the support surface. A circumferential chip surface is adjacent to a peripheral clearance surface, the individual main edge being formed between the chip surface and a part of the clearance surface extending between two corners, and the individual nose edge being between the chip surface and a convex part of the clearance surface. A flank surface, which slopes toward the chip surface, extends from the outer contour line of the support surface. The individual main edge, as viewed in side elevation, declines from a highest point adjacent to the nose edge toward a lowest point between two corners, a level difference between the support surface and the lowest point of the main edge amounts to at most 0.5 mm, and the rake angle (α) of the individual cutting edge is acute along the entire extension of the cutting edge.

摘要： A cutting insert for chip removing machining of workpieces, including at least one chip-removal surface that carries away chips, at least one side surface that is a clearance surface, and at least one cutting edge formed between the at least one chip-removal surface and the at least one side surface. The cutting edge includes a main-edge segment that carries out a major part of a chip-removing operation, and a wiping-edge segment that, in the chip-removing operation, wipes off and levels a machined surface of the workpiece. The wiping-edge segment forms a depression.

摘要： A turning insert includes a chip-breaking surface and first and second clearance surfaces located at a corner of the insert. First and second edges are formed at a junction of the chip-breaking surface and the first and second clearance surfaces, respectively. The first edge defines a major cutting edge, and the second edge defines a finishing cutting edge. The major cutting edge is straight and transforms into the second edge by a sharp transition.

摘要： A cutting insert, intended for chip removing machining includes a cutting geometry surface having a cutting edge from which extends a primary chamfer that transforms into a chip removing surface. The chip removing surface is inclined in a inwards/downwards direction in order to permit sinking of a chip being formed, and transforms into a deflection surface arranged to initiate deflection of the chip from the cutting insert. The angle of inclination of the chip removing surface does not exceed 18°. The level difference in elevation between the primary chamfer and the chip deflection surface amounts to maximally 0.20 mm.
