  • Patent number: 8915166
    Abstract: A bit mold is milled using a turning stage which forms a base mold component and a base gagering component. Next, a blade milling stage is performed in which the base mold component and base gagering component are milled to define integral junkslot formers separated by blade regions. Lastly, a pocket milling stage is performed in which the blade regions and integral junkslot formers of the base mold component are milled to define a plurality of cutter pockets in primary and perhaps secondary rows. Each cutter pocket includes a seat portion and a face portion. The milling of the pocket milling stage provides, at one or more of the cutter pockets, a facet. This facet is provided in an area about the junkslot former associated with the face portion of the cutter pocket, the face portion having, due to the presence of the facet, a surface for matching a cutter core displacement end surface without voids of a size which would require the use of fill material.

  • Patent number: 8813622
    Abstract: A machine for slitting metal sheet into strips includes a fixed upper beam and a lower beam that is displaceable vertically. Both beams support slitter heads that move along the beams. Each beam carries an arbor that rotates in it and extends through the slitter heads on it. Each beam also has a fixed threaded shaft and lock rods that extend through the slitter heads on it. Each slitter head carries a knife that rotates with the arbor for its beam. Each slitter head also has a motor-driven nut that engages the threaded shaft extending through the beam and, when rotated, moves the slitter head along its beam. The slitter heads have clamps, which clamp down on the lock rods to secure the slitter heads in fixed positions.
