GF Machining AgieCharmilles FORM E 350

The AgieCharmilles FORM E 350 is a compact die-sinking EDM with X, Y and Z travels of 350 x 250 x 250 mm, a 270 L dielectric tank and the AC FORM CNC control. It does not appear in GF Machining Solutions' current AgieCharmilles lineup, so most buyers will meet it as a used machine.

Read the table on this page with care. The rows that fit a 350-class machine are the travels, a bath level range of 140-310 mm, a table to chuck distance of 170-420 mm, a best surface finish of 0.1 µm Ra and a machine weight of 1,730 kg. Further down, the same table carries a second set of rows that describe a larger machine: travels of 600 x 400 x 400 mm, a 750 l tank, a table to chuck distance of 190-590 mm, a 1000 x 700 x 400 mm workpiece limit, 1,000 kg workpiece and 100 kg electrode capacity, and a total weight of 4,400 kg. Those cannot all belong to a machine with 250 mm of Z, so treat the larger set as unconfirmed for the 350.

Taken on its own figures, the FORM E 350 suits small cavities and inserts. 250 mm of Z with a 170-420 mm table to chuck range gives room for a moderate electrode stack over a low workpiece; tall parts eat into that quickly. A 270 L tank keeps the dielectric volume modest, which helps where floor space and fluid handling are limited.

Before buying a used machine, measure the travels and the tank, and ask for the generator and control version on the nameplate, since the listed figures have not been matched to a GF product page.
