How much does the GF AgieCharmilles FORM X cost?
Estimated price range
Our best estimate for a sinker edm (ram edm) in this class — not a quote from GF Machining Solutions. Configuration moves it a long way.
Overview
The AgieCharmilles FORM X on this page is listed with 350 x 250 x 250 mm of X, Y and Z travel, a 500 x 350 mm table and a 4-position LTC, which makes it a 350-class sinker rather than one of the larger sizes GF sells today. GF Machining Solutions' current FORM X series comes as the FORM X 400 and FORM X 600, and none of the figures below has been matched to a GF product page.
Set beside these figures, the current AgieCharmilles FORM X 400 lists 400 x 300 x 350 mm travels, 800 kg workpieces, a best finish of 0.05 μm and a machine weight of 3837 kg. This page gives 400 kg workpieces, Ra 0.10 µm and 2,500 kg without dielectric. A buyer offered a used FORM X should therefore read the nameplate and the travel limits before assuming it matches either current size.
Within its own table the machine is well equipped for small mould work. The C axis is standard with full 360-degree rotation, the ISPG generator is rated 80A peak and resolution is 50 nm. Workpieces can measure up to 800 x 500 x 265 mm, while electrodes can weigh up to 50 kg. With four changer positions, a typical job runs one roughing and one or two finishing electrodes per cavity without an operator.
Rapids are 4,000 mm/min on X and Y and 6,000 mm/min on Z, the dielectric volume is 300 liters, and the control is AC FORM HMI.

Strengths & Limitations
Strengths
- Standard C axis with full 360-degree rotation
- 4-position LTC (Linear Tool Changer) for short unattended sequences
- Workpieces up to 800 x 500 x 265 mm and 400 kg
- ISPG generator at 80A peak with 50 nm positioning resolution
Limitations
- Not one of GF's current FORM X sizes, and the figures have not been matched to a GF product page
- Travels of 350 x 250 x 250 mm against 400 x 300 x 350 mm on the current AgieCharmilles FORM X 400
- Best finish of Ra 0.10 µm, coarser than the 0.05 μm of the current AgieCharmilles FORM X 400
- Four electrode positions limit long unattended runs

Frequently Asked Questions
01
No. The current AgieCharmilles FORM X 400 lists 400 x 300 x 350 mm travels, 800 kg workpieces and 0.05 μm best finish. The FORM X on this page lists 350 x 250 x 250 mm, 400 kg and Ra 0.10 µm, which points to an older or smaller machine.
02
Up to 800 x 500 x 265 mm and 400 kg, on a 500 x 350 mm table. Electrodes can weigh up to 50 kg. The travels are 350 x 250 x 250 mm, so a part as large as the size limit can only be eroded within that reach.
03
The listed table gives a C axis as standard with full 360-degree rotation, alongside a 4-position LTC (Linear Tool Changer). Confirm both on any machine you inspect, since these figures have not been matched to a GF product page.
04
The machine is listed at 2,500 kg without dielectric, and the dielectric volume is 300 liters. Add the weight of the filled tank when checking the floor, and measure the tank and travels on the machine itself, since the figures have not been matched to a GF product page.
