    摘要： A face milling cutting tool comprises a cutter body (1) and cutting bits or tips (8) mounted thereon and is characterized in that each cutting tip: is of flat shape with at least one cutting edge of convexly curved contour and has at one part of its peripheral surface a rake surface; is so tangentially mounted that a front clearance face (16) thereof leaves an axial relief angle relative to the surface of workpiece being machined; and is so mounted that the radial rake angle of the curved cutting edge is of a large negative value. The contour shape of a cutting tip (8) may be substantially triangular, rectangular, parallelogrammatic, circular, elliptical, or any other suitable closed figure, or a combination of any of such contour shapes.

    摘要： A metal cutting tool having an exchangeable cutting insert mounted on a replaceable cartridge seat releasably fitted in a tool holder of the cutting, the cartridge seat comprising a body portion with a receiving pocket formed therein, an axially directed external surface of the body portion and a substantially planar rear surface thereof; the receiving pocket being formed with a substantially planar insert receiving surface; the tool holder being formed with an insert receiving cavity having an axially directed internal surface adapted to receive the body portion and a substantially planar end surface adapted to abut said rear surface; one of said axially directed surfaces being substantially cylindrical and the other being formed with three suitably located, axially directed protrusions so that upon the screw coupling together of the cartridge seat in the receiving pocket the body portion pivots about its region of abutment so as to be clamped against the protrusions.

    摘要： Disclosed is a milling cutter in which there is a cutter body having a plurality of insert pockets with each of the pockets having a back wall. There is also an indexable insert having opposed top and bottom surfaces joined by a peripheral wall to form a polygonal body when viewed in plan. The peripheral wall on each side of the insert forms a cutting edge at the juncture of one of the top and bottom faces and a clearance face on each side of the insert joins a peripheral wall and the other of the top and bottom faces. The milling cutter further comprises means for holding the insert in the pocket so that one of the top or bottom surfaces abuts the back wall.
