The Model HE4232 disc holder—designed for use with Hirschmann Engineering USA, Inc.’s (Buffalo Grove, IL) Fixturing System 4000—provides quick and positive clamping of polycrystalline diamond CBN discs. This device ensures that the discs will be held perfectly flat and well into the cutting zone of a wire EDM. The device is mounted to the company’s quick-change pallet system, which allows for off-line setup and alignment. Two clearance holes on 50 mm centers also are provided for permanent mounting directly to the machine table.

The holder is designed for 2.35-inch diameter discs up to 2 inches thick—allowing a maximum cutting area while firmly holding the disc. The distance from the bottom of the disc to the machining table is the same with either mounting so that accurate tapers can be cut. Alternative versions of the holder for different diameter discs also are available.
