  • Method and apparatus for cross-passageway pressing to produce cutting inserts
    Patent number: 8033805
    Abstract: A die for use with a uni-axial press including top and bottom rams, at least one of the top and bottom rams being movable along a pressing axis. The die includes at least two separable die parts mutually engageable along adjacent parting surfaces extending in a direction non-perpendicular to the pressing axis and a removable core rod. The die parts are movable between separated and engaged positions in a direction non-parallel to the pressing axis. The die includes a first passageway extending therethrough between the periphery of the die and the die chamber. The first removable core rod is configured to be inserted into the die chamber through the first passageway.

  • Method and apparatus for cross-hole pressing to produce cutting inserts
    Patent number: 6986866
    Abstract: A method and apparatus for the cross-hole pressing of cutting inserts is disclosed whereby a green part is fabricated using metallurgical powder and an opening is imparted within the green part by placing the metallurgical powder about an oval-shaped core rod. Using a press with a uni-axial press motion, a core rod is placed within the cavity of a mold and metallurgical powder placed around the core rod and thereafter compressed to form a green part. The subject invention is also directed to an article formed utilizing such a process and the uni-axial press used to produce such an insert.
