摘要： A cutting tool includes a two-way indexable cutting insert retained in a tool holder by a clamping member. The cutting insert has a tetrahedral basic shape and includes two cutting edges at opposite ends of thereof. The insert holder includes a forwardly located mounting portion that includes three spaced apart mounting jaws which together define an insert receiving pocket having a pocket opening. The clamping member is attached to the insert holder body so that a clamping portion of the clamping member protrudes into the pocket opening. When the cutting insert is releasably attached to the insert holder in a fastened position of a cutting tool, the cutting insert is located in the insert receiving pocket and clampingly engaged therein by the clamping portion.

摘要： A turning insert includes a top surface, an opposite bottom surface, a reference plane located parallel to and between the top surface and the bottom surface, and a center axis extending perpendicular to the reference plane and intersecting the reference plane (RP), the top surface and the bottom surface. Side surfaces connect the top surface and the bottom surface. Three nose portions are formed symmetrically relative to the center axis. Each nose portion includes a first cutting edge, a second cutting edge and a convex nose cutting edge connecting the first) and second cutting edges. In a top view the first and second cutting edges on the same nose portion form a nose angle of 25-50° relative to each other. The distance from the first cutting edge to the reference plane varies in such a way that that this distance is decreasing at increasing distance from the nose cutting edge.

摘要： A method for manufacturing a cubic boron nitride cutting tool including a base metal and sintered cubic boron nitride compact at a corner portion of the base metal, capable of improving the accuracy of the center height and reducing the angle of inclination or width of a negative rake face; and the cubic boron nitride cutting tool. The method includes grinding the compact by pressing it against an end face of a grindstone of a grinder to form flank and rake faces on the compact while the base metal of the cutting tool is held by a chuck of the grinder, so that the compact is substantially ground. The rake face is formed to be recessed from a top face of the base metal or only a portion of the compact that protrudes from a base-metal rake face is ground while the tool is continuously held by the chuck.

摘要： A turning tool including a basic body having an insert seat, an indexable turning insert having a triangular basic shape, and a tightening element fixing the turning insert in the insert seat. The insert includes an upperside and an underside between which three side surfaces extend that are situated in a first imaginary, equilateral triangle and therefore converge in pairs at an angle of 60° toward corners in which cutting edges are included. The turning insert is engaged with the insert seat via an interface that includes elongate and straight, female-like and male-like engagement members, which are in engagement with each other in order to prevent turning of the turning insert. The insert seat includes a supporting surface having a corner section against which an active corner of the turning insert is applied. The insert seat includes a single active engagement member, which is spaced-apart from the supporting corner section, and is in engagement with one of three engagement members included in the turning insert and located in a second imaginary triangle having an equilateral shape, which is smaller than the first imaginary triangle and rotated in relation to the first imaginary triangle.

摘要： An object of the invention is to reliably control chip, particularly that produced in profiling. To achieve this, rake faces are formed on polygon faces of an insert in the form of a polygonal plate shape, and a pair of cutting edges extending respectively from corner parts of the polygon faces are formed on a ridge part of the polygon faces, and each of the rake faces is gradually inclined as it becomes farther away from the cutting edge, and a land formed along the cutting edge, is inclined so that it gradually sinks as it become farther away from the cutting edge at an angle of inclination smaller than a rake angle, and angles of inclination of these rake face and land are made smaller in the direction to separate from a tip of the corner part along the cutting edge, and a main convex being a convex spherical face shape is formed at intervals between the cutting edges, on the corner part C, and at least one pair of sub convexes being a convex spherical face shape is also formed respectively at positions away from this main convex, along the pair of cutting edges.

摘要： A cutting tool for removing material from a workpiece wherein the cutting tool is held in a pocket of a tool holder. The cutting tool includes a cutting tool substrate with a rake surface and flank surfaces, as well as a notch at the intersection of a pair of adjacent ones of the flank surfaces. The substrate includes opposite flank surfaces that are opposite from the notch and are disposed at a substrate disposition angle with respect to the rake surface of the cutting tool substrate. The cutting tool further includes a cutting blank that is within the notch. The cutting blank has a rake surface and a pair of exposed flank surfaces wherein a cutting edge is at the intersection of the rake surface and the exposed flank surfaces. The exposed flank surfaces of the cutting blank are disposed at a cutting clearance angle with respect to the rake surface of the cutting blank. The cutting clearance angle is not equal to the substrate disposition angle.
