Excetek ED800C CE

The ED800C CE is Excetek's CE-designated die sinking EDM in the 800 class, and on paper it is the heavier-duty table of the two 800 models. It keeps the ED800C travels of 800 mm (31.5 in) in X, 600 mm (23.6 in) in Y and 500 mm (19.7 in) in Z, then raises workpiece weight to 5,000 kg (11,023 lb) on a work table of 1,250 x 750 mm (49.2 x 29.5 in).

What it gives back is at the head. Maximum electrode weight is 300 kg (661 lb), where the ED800C is listed at 350 kg (772 lb). For most cavity work that gap will never be reached; for the largest graphite forms it is the row to check first.

Maximum workpiece size is printed as 1,700 x 1,000 mm (66.9 x 39.4 in), a plan dimension with no height. The machine weighs 5,300 kg (11,684 lb) and, with body, travel, tank and generator, fills 3,150 x 3,150 x 3,100 mm (124.0 x 124.0 x 122.0 in), a square footprint slightly lower than the standard machine's 3,200 mm.

Filtration is arranged differently as well. The oil filter tank holds 1,430 L and is fitted with six paper filters, two more than on the ED800C, at the same 450 kg (992 lb) tank weight. More filter area for a similar oil volume should lengthen the interval between element changes during heavy roughing with graphite. The rest of the description is shared with the ED series: MOSFET sparking circuit, a generator split into front and back modules for service access, roller type linear guide ways and a work table hardened to HRC50. Oil cooling, a permanent magnetic pedestal and the tungsten carbide circuit are options.
