Definitions

  • Workpiece 2 is bolted or clamped to a moving table 10, which is slidable on track 7 (shown in phantom), so that workpiece 2 can move with respect to tooling post 8 and shaping cathode 6.
  • the moving table 10 has an aperture or slot 10A through which the tooling post 8 projects upwardly. The slot permits the table to move with respect to tooling post 8 to bring workpiece 2 and cathode 6 into close proximity during the electrochemical ma chining process.
  • FIG. 9 shows a magnified view of the top part of tooling post 8 to illustrate how the shaping cathode 6 can be attached to either side of tooling post 8 and how fine adjustments can be made in the position of the shaping cathode.
  • a plurality of the above air outlets distributed in a uniform manner about the upper surface of support ring 29 will permit ring 28 to rise upon application of air pressure, and to remain level on a blanket of air while being rotated.
  • An apparatus used in electrochemically machining a conductive metal workpiece which comprises: a table having a work-supporting surface, said table having an aperture in said surface; means for holding the workpiece on said work-supporting surface; an elongated member extending throu h said aperture in a direction generally perpendicular to said work-supporting surface; an electrolyte shaping cathode; means for holding said electrolytic shaping cathode on said elongated member in a position spaced from said workpiece and extending generally parallel to said Work-supporting surface; means for displacing said table and said cathode holding means with respect to each other to bring said workpiece and said cathode into close proximity with each other; and means for connecting a source of DC voltage across said workpiece and said cathode to make said workpiece anodic.
