Graphite Electrodes and EDM Processes

The use of graphite electrodes is common in the EDM process, providing an economical solution compared to other electrode materials, and less wear on the electrode itself. Absolute also offers a wide selection of AccuteX Die Sinkers for burning.

The AccuteX Die Sinker DS ZNC (manual) series of four RAM-type EDM machines can handle maximum workpiece sizes from 38″ x 22″ x 14.9″ (965 mm x 558 mm x 378 mm) to 67″ x 39″ x 22″ (1700 mm x 990 mm x 558 mm). It’s optional COC-280 Orbit Cut System, when added to the standard Automatic Z Axis Step function, performs like a full 3D machine producing super fine finishes down to 0.18 Ra µm and accuracies to 0.0002″ easily and efficiently.

The AccuteX Die Sinker CMAX Series is a RAM-type CNC EDM machine offering a full range of 10 different model sizes and capabilities. The fully functional C-Axis can be fit with any commercial chuck for electrode holding compatibility and can hold up to 50 pounds. Shuttle and rotary automatic electrode changers or standalone FANUC or Mitsubishi robot can be installed to accommodate untended operations from roughing to finishing changing electrodes and work pieces.
