摘要： A cutting insert for mounting on a milling cutter has a generally quadrangular shape with top and bottom surfaces, a pair of opposite first side surfaces intersecting the top surface at first cutting edges and a pair of opposite second side surfaces intersecting the top surface at second edges. Each second edge has a front cutting portion oriented substantially transversely to an adjacent first cutting edge and meeting therewith via a cutting corner. Each of the first and second side surfaces has upper and lower sections adjacent respective top and bottom surfaces, which sections have leading portions adjacent their associated cutting corner and trailing portions remote therefrom. The trailing portion of the lower section of each second side surface is at least slightly inwardly depressed relative to the leading portion of the lower section and is substantially inwardly depressed relative to the associated trailing portion of the upper section of the second side surface. The trailing portions of the lower and upper sections merge via a transition surface oriented transversely thereto.

摘要： A cutting insert includes a first surface and a second surface each of which is polygonal and that face away from each other; a side surface that is continuous with the first surface and a side surface that is continuous with the second surface; a cutting edge formed along each of a ridge where the first surface and the side surface intersect and a ridge where the second surface and the side surface intersect; a bearing surface formed in each of a part the first surface and a part of the second surface adjacent to an insert center, the bearing surfaces disposed parallel to each other; and a recessed portion that separates the side surface that is continuous with the first surface from the side surface that is continuous with the second surface. The cutting edge includes three corner edges, a first cutting edge, and a second cutting edge, the first and second cutting edges being continuous with each other and located between each pair of the corner edges. A length of the first cutting edge is greater than that of the second cutting edge, an end portion of the first cutting edge adjacent to one of the corner edges is at a position higher than the bearing surface, and an end portion of the first cutting edge opposite to the end portion adjacent to the corner edge is at a position lower than the bearing surface. Each of the first surface, the second surface, and a cross section of the recessed portion has such a shape that outlines of the shape before and after rotation of the insert by 120° around the insert center are coincident with each other. The first surface and the second surface have the same shape, and the second cutting edge of the second surface is located at a corner at which the first cutting edge of the first surface is located.

摘要： A throwaway insert and a cutting tool enable a high speed cutting operation for a metallic material having great ductility such as aluminum and obtaining a vertical wall with a high quality machined surface while improving chin control. The throwaway insert comprises a major cutting edge including a tapered cutting edge connected to a cutting edge of a nose portion, and a curved cutting edge connected to an end of the tapered cutting edge at a connection point. The curved cutting edge is formed so as to extend along an imaginary cylindrical surface whose center axis coincides with the axis of rotation of a tool main body, and tapered cutting edge is formed so as to gradually curve from the imaginary cylindrical surface toward the inside of the imaginary cylindrical surface as the distance from the curved cutting edge increases, and the distance from the nose portion decreases. The throwaway insert is attached to the tool main body in which the surface of the distal end thereof is machined so that surface roughness thereof is less than 3.2 nullm when indicated by the Ry roughness.

摘要： A slotting cutter includes a circular disc having an outer periphery along which a plurality of chip channels are formed which define respective seats for receiving respective index able cutting inserts. Each insert includes a planar bottom side. Either the seat or the bottom side has a male locator portion, and the other of the seat and the bottom side has a female locator portion which receives the male locator portion to define therewith and insert-locating structure. The male and female locator portions are offset laterally from a center plane of the insert oriented perpendicular to an axis of rotation of the disc. Alternating ones of the insert-locating structures are disposed on respective opposite sides of the center plane.

摘要： A cutting tool, for milling, comprises a holder and a cutting insert. The cutting insert has a generally octagonal basic shape and has at least two cutting edges created by a transition between an upper face and an edge face of the cutting insert. The upper face constitutes a rake face and the edge face constitutes a clearance face, created at the transition of two adjacent cutting edges. The edge face forms a clearance angle of at least 20 degrees with a plane extending parallel to a center axis of the insert. The edge face is provided with a step which defines a fracture zone. The step forms an angle with a line extending perpendicular to the center axis. Cutting corners of the insert are beveled to form an angle greater than an angle formed by adjacent cutting edges.

摘要： A cutting insert for use in a rotary milling tool is provided. The cutting insert includes an insert body including a bottom face, a top face, and a side face. A stepped cutting edge is formed at the intersection of the top face and the side face for engaging a workpiece and removing a chip from it. The stepped cutting edge includes at least two offset edge portions which produce distinct, transversely-spaced chip segments during the cutting operation. The offset edge portions are connected by transition edge portions which are disposed at an obtuse angle with respect to the offset edge portions. The angle of the transition edge portions tends to spread the individual chip segments apart during the machining operation to effect a thinning of the chip between the individual chip segments. The entire cutting edge is helically curved so that the cutting edge lies on the surface of a circumscribing cylinder defined by the rotation of the cutting edge about the axis of the milling cutter.

摘要： A cutting bit, in particular an indexable cutting bit, has a polygonal base body with a flat bottom side (1), a flat or structured top side (4) spaced apart from the bottom side, and a number of side surfaces (2) adjoining one another, forming corners (3). On the top side, the base body is beveled to descend in the outward direction of the region of the chip removing surface at at least one corner (3), in such a way that at the corner a delimited region (9) is formed that is inclined with respect to the bottom side (1). In this inclined region (9), on one side of the corner (3), the main cutting edge (5a , 5b) extends to the vicinity of the corner (3), while on the other side of the corner in the inclined region a plane, or facing, cutting edge (5c) is formed, which essentially adjoins the main cutting edge, and the portion of the main cutting edge located in the inclined region (9) has essentially at most the same length as the plane cutting edge.
