摘要： A four-sided cutting insert has a top surface, a bottom surface, and a pair of first side surfaces connected to a pair of second side surfaces via corner surfaces. The cutting insert has a rotational axis of symmetry, a first axis extending along the first side surfaces and second axis extending along the second side surfaces. Opposite corners of the cutting insert are provided with a first pair of corner edges defined between a first edge and an associated second edge. Proximate its leading end, the first edge has a main portion which, in a top view of the insert, extends inwardly toward the first axis at a first angle. In a side view, the first edge slopes downwardly from the corner edge in the direction of the base surface. The associated second edge, in the top view of the insert, extends from the corner edge in an outward direction relative to the second axis.

摘要： A cutting insert intended exemplarily for use in a face-milling cutter, has an all-around extending rake surface which changes into a plateau surface by an uninterrupted step. The step reaches its greatest height in the corner regions of the cutting insert. The rake surface defines a positive rake angle. The step prevents the produced chips from running onto the plateau surface. As a result of such a measure, a smear-on of material onto the plateau surface from a chip is prevented.

摘要： The invention relates to an indexable drill for drilling a hole in a metal workpiece. The drill includes an elongated generally cylindrical body having a central longitudinal axis and a pair of cutting inserts. The body includes a tip end portion having first and second recessed pockets on generally diametrically opposite sides of the longitudinal axis. Each cutting insert is removably secured within a pocket and includes at least one cutting edge having an outer peripheral corner and an inner corner. The at least one cutting edge extends linearly from the outer peripheral corner to a curve extending convexly toward an inner region proximate the central longitudinal axis and then to a linear relief edge extending linearly from the inner region in a direction away from the longitudinal axis to the inner corner.

摘要： A rotary cutting tool for cutting a spherical seat on a surface of a workpiece comprises a body adapted to carry cutting inserts. The body is fixed to a drive shaft which rotates the body about a longitudinal center axis of the body. The body includes a forwardly facing front surface of generally convex shape, and a plurality of insert seats formed in the front surface in circumferentially spaced relationship about the axis. Each of the seats faces forwardly and comprises recesses of generally pyramidal shape. A screw threaded hole extends through each of the seats in a rearward direction and is adapted to receive an insert fastening screw. The cutting inserts include projections of generally pyramidal shape received in respective ones of the recesses. The projections are formed by a first plurality of V-shaped parallel grooves intersected by a second plurality of V-shaped parallel grooves arranged perpendicular to the first groove.

摘要： A cutting insert (1) for use in a milling cutter for a face milling has upper, lower and side surfaces and at least one pair of main and minor cutting edges (10, 11) formed by the intersection between the upper surface (5) and an adjacent side surface (7). The cutting edges (10, 11) merge via a cutting corner portion (12) of a relatively large radius, which is provided with a land (15) formed at the upper surface (5) of the insert. The land (15) is inclined to the insert lower surface at an inclination angle which continuously varies from a negative value at an area of the corner portion (12) adjacent the main cutting edge (10) to a positive value at an area of the corner portion (12) adjacent the minor cutting edge (11).

摘要： An on-edge indexable cutting insert in which each end of the insert is formed with a convexly curved surface which gradually decreases in area per unit of length as the curved surface proceeds away from the cutting edges so as to form each cutting edge with a convexly curved tip of relatively large radius while leaving a flat and planar locating surface of substantial area on each end of the insert.

摘要： A cutting insert includes a main body including a first face, a second face, and a third face. The second face includes a rake face. Among the outer-peripheral sides of the second face, the boundary portion with the first face is a main cutting edge. When viewed from the side where the first face is disposed, the main cutting edge includes a first straight portion, a second straight portion, and a curved portion. The first straight portion is located adjacent to a reference side. The second straight portion is arranged at a distance from the first straight portion. The curved portion connects the first straight portion and the second straight portion. A first intersection angle of the first straight portion with respect to the reference side is different from a second intersection angle of the second straight portion with respect to the reference side.
