摘要： A double-sided, indexable face milling insert, including an upperside, an underside, and a neutral plane (NP) parallel to the upperside and the underside, the neutral plane forming a right angle with a geometrical center axis (C2). A plurality of indexable cutting edges are formed along circumferential borderlines in transitions between a number of clearance surfaces and the upperside as well as the underside. Each cutting edge includes a chip-removing main edge and a surface-wiping secondary edge, the secondary edge forming an obtuse angle with the main edge in planar view. A corner clearance surface extends between and connects each pair of upper and lower secondary edges, the corner clearance surface including first and second part surfaces which each form an acute angle (η) in side elevation view with respective reference planes (RP) parallel to the neutral plane.

摘要： A milling insert, including an upperside, an underside, and a reference plane parallel to the upperside and the underside. A plurality of indexable cutting edges are formed along a peripheral borderline in transitions between at least the upperside and a number of clearance surfaces. Each cutting edge includes a chip-removing main edge and a surface-wiping secondary edge, the secondary edge forming an obtuse angle with the main edge as viewed in planar view from the upperside. The main edge, from a first end of the main edge adjacent to the secondary edge, first declines toward the underside of the milling insert and then, from a lowest part, rises toward an opposite second end of the main edge. The secondary edge is inclined at an angle (ε) in relation to the reference plane as viewed perpendicularly to the clearance surface of the secondary edge, such that a first end of the secondary edge connected to the main edge is situated on a lower level than the opposite, second end of the secondary edge.

摘要： A drilling tool includes a basic body defining a center axis of rotation and having two chip channels and two replaceable indexable cutting bits in the form of a center bit and a periphery bit mounted in respective center and periphery pockets formed in an axially front end of the basic body. The center bit and the center pocket are spaced radially from the periphery bit and the periphery pocket along a first diametrical plane of the basic body. At least the center bit includes four identically-shaped cutting edges, one of which constituting an operative cutting edge intersected by a second diametrical plane oriented perpendicularly to the first diametrical plane. Each cutting edge of the center bit comprises first and second part edges joined by a transition edge portion. The first and second part edges of the operative cutting edge constitutes operative first and second part edges, respectively; the operative first part edge being spaced from the center axis and situated closer than the operative second part edge to an outer periphery of the basic body. An axially forwardmost portion of the operative first part edge is disposed axially forwardly of an axially forwardmost portion of the operative second part edge, and an axially forwardmost portion of an operative cutting edge of the periphery bit lies axially between the axially forwardmost portions of the operative first and second part edges of the center bit, respectively.

摘要： A drilling tool set includes a plurality of drilling tools having different operative drill diameters to blast drill holes of different respective diameters. Each drilling tool of the set has a basic body defining a central axis of rotation, and two replaceable indexable bits including a center bit and a periphery bit which are mountable in respective center and periphery pockets formed in a front end of the basic body. The periphery bits of the respective drill tools of the set are identical, and the center bits of the respective drill tools of the set are identical. Each of the center and periphery pockets of each drill tool defines a radial center point. A first of the drill tools has a smaller operative drill diameter than a second of the drill tools. The first tool includes a first periphery pocket and a center pocket. The center point of the first periphery pocket is disposed closer to the axis than is the center point of the second periphery pocket. The center point of the first center pocket is disposed closer to the axis than is the center point of the second center pocket.

摘要： An indexable cutting insert for metal machining comprises an upper rake surface, a bottom surface and side surfaces that extend between the upper and bottom surfaces. Cutting edges are formed at the transitions between the side surfaces and the upper surface. Disposed along the cutting edges on the upper surface are elongated primary lands. Disposed inside of the lands is a chip-breaking depression. A raised land area to be ground is situated in the chip-breaker, so that the total grinding area of the upper surface becomes about as large as the total grinding area of the bottom surface. The insert can thus be ground by upper and lower grinding wheels which rotate simultaneously in opposite directions.
