METHOD AND APPARATUS FOR CROSS-HOLE PRESSING TO PRODUCE CUTTING INSERTS

摘要

A method and apparatus for the cross- hole pressing of cutting inserts (10) is disclosed whereby a green part (110) is fabricated using metallurgical powder (260) and an opening (25) is imparted within the green part by placing the metallurgical powder about an oval-shaped core rod (235). Using a press (200) with a uni-axial press motion, a core rod is placed within the cavity (210) 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.
