摘要： A cutting insert for a tool for machining a workpiece. The cutting insert comprises a rake face with a chip shaping geometry which is particularly suitable for machining titanium and titanium alloys. The chip shaping geometry is designed in such a way that the chip lifted from the workpiece is deformed comparatively strongly about its longitudinal axis. The chip shaping geometry is arranged at least in a rear area of the rake face, which is laterally bounded by a first concavely curved portion and a second concavely curved portion of the minor cutting edges of the cutting insert. The chip shaping geometry projects upwardly beyond a cutting plane in which the main cutting edge of the cutting insert and two rectilinear portions of the two minor cutting edges are arranged and comprises at least two elevations so that the rake face in the rear area in a further cross-section parallel to the main cutting edge comprises two high points and an intermediate second low point which has an equal third distance from the first concavely curved portion and the second concavely curved portion. A rake angle along the main cutting edge varies such that the rake angle γ1 at a center of the main cutting edge, which has an equal second distance from a first end and a second end of the main cutting edge, is greater than the rake angle in the area of the first and/or second ends.

摘要： An insert holder has a holder longitudinal axis defining opposite forward to rearward directions, a holder end surface located at a forward end thereof, and a holder peripheral surface extending circumferentially about the holder longitudinal axis. The insert holder has upper and lower jaws which are spaced apart by a clamping recess recessed in the holder end surface. The upper jaw is resiliently movable with respect to the lower jaw upon rotation around an angled pivot axis. The insert holder includes a forwardly located insert mounting portion which includes a forwardly protruding clamping finger and a forwardly protruding support rib. The clamping recess is defined partially by an elongated recess hinge surface formed on an angled hinge portion. The recess hinge surface includes a first hinge end and a second hinge end, longitudinally spaced apart from one another. The second hinge end is located forward of the first hinge end.

摘要： A cutting tool includes a holder and a cutting insert releasably clamped in the holder. The holder has a rear pocket surface which includes a pocket abutment surface and an adjacent pocket wedge surface. The cutting insert has at least one abutment surface and an adjacent wedge surface. When the cutting tool is assembled but not in use, the pocket abutment surface of the holder abuts the abutment surface of the cutting insert, and the wedge surface of the holder is facing and spaced apart from the wedge surface of the cutting insert. During cutting operations, the wedge surface of the insert may abut against the wedge surface of the holder.

摘要： A tool is provided having a tool holder and a brazed top clamp positioned in a portion of the tool holder. The brazed top clamp is made of a material that has a hardness that is greater than the material that makes up the tool holder. In certain embodiments, the tool holder has a slot that is in the shape of a “T-slot” and the top clamp is in the shape of a “T shaped rail” that is positioned within the “T-slot” of the tool holder.

摘要： An indexable parting blade has opposite blade first and second sides, a blade peripheral edge, a central index axis, and at least first, second and third insert pockets located along the blade peripheral edge. The parting blade also has first, second and third coolant channels, each forming a coolant path from a corresponding inlet to a corresponding one of the insert pockets. Each coolant channel includes a rake outlet opening out to a rake side of its corresponding insert pocket and a relief outlet opening out to a relief side of that same insert pocket. The inlet corresponding to a given coolant channel is located further from that coolant channel's insert pocket than at least one of (a) the inlet corresponding to a different coolant channel, and (b) the central index axis.

摘要： A turning insert includes a head portion connected to a stem portion. A CBN cutting edge includes a surface generating cutting edge and two major cutting edge portions, such that each major cutting edge portion forms an angle of 5-20° in relation to a tangent line of the cutting edge at a forward point of the cutting edge.

摘要： A method of efficiently forming a finished part, the method includes providing a cutting tool having a first cutting edge extending from a first end of the cutting tool, a second cutting edge extending from a second end of the cutting tool, and a shaping edge disposed between the first cutting edge and the second cutting edge. The cutting tool is advanced into a rotating workpiece such that the first cutting edge removes a trailing end of the rotating workpiece, the shaping edge shapes a working portion of the rotating workpiece, and the second cutting edge removes the working portion of the rotating workpiece to form the finished part.

摘要： A cutting insert may include a base and a cutting part. The cutting part may include an upper surface, a first cutting edge and a second cutting edge. The first cutting edge may be located on a first ridgeline. The second cutting edge may be located on a second ridgeline. The upper surface may include a first inclined surface, protrusions and a first upheaved part. The first inclined surface may be located along the first ridgeline. The protrusions may be located side by side in a direction along the first ridgeline on the first inclined surface. The first upheaved part may be located at a side further away from the first ridgeline than the pair of protrusions. The second cutting edge may be inclined downward. An upper end of the first upheaved part may be located above the second cutting edge.
