摘要： A milling tool for the milling of a slot in a workpiece includes a plurality of cutting inserts, which comprise an under side; an opposite upper side, which forms a chip surface and extends parallel to an extension plane; and an edge side between the upper side and the underside. A cutting edge, which extends between the edge side and the chip surface, includes a primary main cutting edge; a front cutting edge, which extends along an edge line; and a primary corner cutting edge, which extends between and connects the primary main cutting edge and the front cutting edge. The primary corner cutting edge has a convex shape and extends, with respect to a rear portion of the cutting insert, forward from the front cutting edge to a position on the other side of an imaginary line, which forms an extension of the edge line and extends in a tangential direction to a point on the primary corner cutting edge.

摘要： An indexable cutting insert for chip removing machining includes a plurality of cutting tips that protrude from a central core. Each of the individual tips include a cutting edge, which is formed in a transition between an upper side serving as chip surface and a clearance surface, which extends between the upper side and an under side. The cutting insert has six equally long cutting tips that are located in pairs along the co-ordinate axes of a three-dimensional, orthogonal system of co-ordinates, the origin of which is situated in the core. By arranging the cutting tips in this way, the inactive cutting tips, which are situated behind an active cutting tip, can be contained within a limited volume and therefore be installed in tool basic bodies having tapering parts. A tool equipped with the cutting insert according to the invention, as well as, a tool basic body is disclosed.

摘要： A cutting insert includes a cutting edge formed at an intersection of a rake face formed on a first surface and a relief face with a positive relief angle. The relief face includes a major relief face located adjacent to a major cutting edge, a first minor relief face located adjacent to the first minor cutting edge, and an intermediate relief face located adjacent to the intermediate cutting edge and extending between the major relief face and the first minor relief face. The intermediate relief face includes a protruding curved relief face extending from the first surface. An intersection of the curved relief face and the rake face has a predetermined radius of curvature and has substantially the same shape as that of an intersection of the curved relief face and a second surface.

摘要： A pair of sub-flank surfaces is formed at a vertex angle portion of an insert body having a substantially polygonal, plate-like shape, and between the sub flank surfaces, a vertex flank surface at a vertical angle portion is formed substantially in a protrusive, curved shape, and is smoothly connected to the sub-flank surfaces in a tangential direction. The vertex flank surface at the vertex angle portion is extended across the entire thickness of the insert body, and boundary lines, between the vertex flank surface at the vertex angle portion and a pair of minor cutting edges, are parallel to each other. A second curved ridge line, which is formed between (i) the flank surface and (ii) the rake surface, and a first curved ridge line, which is formed between (i) the flank surface and (ii) the seat surface, have approximately same shape.

A through hole includes a first section mouthing in the upperside, and a second section mouthing in the underside and having a diameter that is smaller than a diameter of the first section.
