Excetek ED600C CE

Three rows separate the Excetek ED600C CE from the ED600C: electrode weight, tank capacity and outside dimensions. The working envelope is common to both. This CNC die sinking EDM has 650 mm (25.6 in) of X travel and 400 mm (15.7 in) of Z, a 1,000 x 600 mm (39.4 x 23.6 in) work table and a 1,290 x 700 mm (50.8 x 27.6 in) maximum workpiece.

Electrode weight is the row with consequences at the spindle. The CE model is listed at 150 kg (331 lb). The ED600C is listed at 50 kg (110 lb). A 150 kg limit admits large graphite forms and gang-mounted electrodes that the other machine cannot hold, which suits a table of this size.

The second difference is the dielectric volume, 1,000 L here against 1,200 L on the ED600C, still with four paper filters and a 350 kg (772 lb) tank weight. The third is the installation envelope. With body, travel, tank and generator the CE machine measures 2,110 x 2,580 x 2,575 mm (83.1 x 101.6 x 101.4 in). It is narrower than the ED600C in the first dimension and slightly lower. Machine weight is identical at 3,900 kg (8,598 lb).

As with the ED600C, Y travel and workpiece weight are worth confirming with the supplier for this model. Excetek's short description calls it the optimum size EDM for most molds. The generator text is the series standard: MOSFET sparking circuit, front and back module assembly, separate heat paths for hot components and cold circuits. From the ED Series catalogue come the Z axis counterweight, ISO G code programming and an optional ATC system.
