  • Patent number: 6006564
    Abstract: The present invention applies dry lubricant to appropriate components of a forming die of a stamping press to minimize frictional force against such components during operation of the forming die or to appropriate components of a forging die of a forging press to minimize shear force against such components during operation of the forging die. A layer of dry lubricant is applied to any one or more of the die, the punch, or the binder of a forming die of a stamping press, and a layer of hard chrome may also be plated thereon before the layer of dry lubricant is applied. A layer of dry lubricant is applied on the inner surface of a cavity within a forging die of a forging press of the present invention. A dry lubricant may also be applied on the outer surface of the punch of the forging press.

  • Patent number: 5318094
    Abstract: The production of complex cavities inside castings or semi solid forms is effected by forming a core pattern (10) of a low melting point metal in order to provide a rigid metal core pattern (10). The pattern (10) is then nickel coated using either electroplating or electroless nickel plating. The metal core pattern (10) is melted out of the nickel plating to provide a nickel liner core (16). The nickel liner core (16) is placed within a mold or die cavity, and molten metal introduced into the cavity in order to provide a casting or form (30). The casting or form (30) is removed from the cavity and includes therein a plurality of passageways (20) each of which is defined and surrounded by a corrosion resistent nickel liner surface (22).

  • Patent number: 4204787
    Abstract: A milling cutter is disclosed that comprises a rotatable adapter plate having a central protrusion on one side of the plate. A cutter ring, having recesses for mounting inserts therein, is provided with bayonet slots and a central opening so it can be fitted with and bolted to the adapter plate. The central protrusion is tapered and a conical grind is put on one of the mating surfaces between the adapter and the cutter plate to aid in disassembly after use of the milling cutter.
