摘要： A drilling tool having an elongated body with a longitudinal axis and provided with at least one insert receiving pocket and an indexable cutting insert for use with the drilling tool for performing drilling action is disclosed. The insert of the drilling tool includes a rake face, relief flank faces, a base, a plurality of cutting edges, each defined between the rake face and adjacent relief flank face and included between two adjacent cutting corners. Each cutting edge has at least one set of component cutting edges, each set having two pairs of component cutting edges merging in a common point, each pair comprising a first and a second component cutting edge merging via a bridging section directed towards a central line constituting or parallel to a median line of the insert and passing through the common point. The component cutting edges are oriented with respect to the central line so that an outermost extremity of the second component cutting edge is closer to a center of the insert and to the central line than the outermost extremity of the first component cutting edge. This ensures that during the drilling action, a line parallel to the longitudinal axis and passing through the outermost extremity of the first component cutting edge intersects the second component cutting edge and the extremities overlap.

摘要： A multi-cornered cutting insert includes a corner cutting edge at each corner, and a chipbreaking recess spaced inwardly of each corner cutting edge. The recess is curved as the insert is viewed in plan. A clearance face for each corner cutting edge has a clearance angle which progressively increases toward the respective corner.

摘要： A cutting insert for chip forming machining comprises an upper rake face, a lower face, and an edge clearance face interconnecting said upper and lower faces. The edge clearance face includes a step located intermediate the upper and lower faces. The step defines a fracture zone so that in the event of insert breakage, the location of the breakage can be controlled. The portion of the insert located below the step defines, in effect, an integral shim.

摘要： An end mill includes a body having a core receiving recess and a cutting insert releasably mounted thereon. An upper surface of the insert has a first cutting edge ridge serving as an outer peripheral cutting edge, a second cutting edge ridge providing an end cutting edge and a third cutting edge ridge providing an inner peripheral cutting edge. The upper surface has a corner where the second and third cutting edge ridge intersecting each other. The upper surface is composed of a central portion and a corner portion including the corner, whereby the third cutting edge ridge comprising a first edge portion defined by a ridge of the corner portion and a second edge portion defined by a ridge of the central portion. At least that portion of the corner portion disposed adjacent the central portion is inclined providing a thickness of the insert is progressively reduced toward the corner. The insert has a negative radial rake at the outer peripheral cutting edge and a positive axial rake. The second edge portion extends radially outwardly of the body and in a direction opposite to the direction of rotation of the body from that point where the first and second edge portions intersect. The distance between the corner and the axis is longer than between the axis and a point at which a line extending radially outwardly of the body from the axis and a line on which a corner ridge lies cross at right angles.

摘要： An end mill comprises an end mill body and a throw-away tip mounted on a forward end of the end mill body so as to be spaced from an axis thereof. A core receiving recess is formed at a center of a forward end face of the end mill body and has a size equal to or greater than a distance between the throw-away tip and the axis of the end mill body. The throw-away tip has an end cutting edge formed by a cutting edge ridge located adjacent the forward end of the end mill body and extending from an outer peripheral side of the end mill body toward an inner peripheral side thereof, and outer and inner peripheral cutting edges respectively formed by cutting edge ridges respectively extending from outer and inner peripheral ends of the end cutting edge toward a rearward end of the end mill body. The end mill body may mount at least two throw-away tips disposed symmetrically with respect to the axis thereof.

摘要： In a triangular turnround cutting plate, in particular for precision machining, a main cutting edge (3, 3a, 3b) defines an acute angle with the adjoining auxiliary cutting edge (4a, 4b, 4). A continuous radius (R) is provided between the two cutting edges (3, 3a, 3b and 4a, 4b, 4, respectively) and the length (L) of all three sides is the same. The radius (R) is in the range of 0.15 to 0.3 times the size of the length (L) of the sides of the turnround cutting plate (1) and the center (M) of this radius (R) is arranged offset from the main cutting edge (3, 3a, 3b) at a distance (a, a1) towards the center of the turnround cutting plate (1) which is in the range of 0 to 0.3 times the radius (R).

摘要： A cutting tool of the broach type for holding a plurality of disposable and indexable cutting inserts. The broach tool comprises a holder body having a plurality of transverse grooves on its peripheral surface, each of the grooves containing a plurality of spaced cutting inserts. The cutting inserts, generally U-shaped, straddle projections in the base of the groove for lateral location of the insert. A wedge member adjacent the inserts cooperates with the projections to hold each of the inserts in spaced location in the grooves of the holder body.
