How much does the GF AgieCharmilles FORM S 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
Listed here as the AgieCharmilles FORM S, this is a die-sinking EDM with a 12-position ATC, an IPG generator rated 120A peak and travels of 350 mm in X, 250 mm in Y and 350 mm in Z. GF Machining Solutions' current lineup has no unnumbered FORM S, and the figures below are listed values that nobody has matched to a GF product page. Read them as a starting point for checking a used machine.
The current AgieCharmilles FORM S 350 makes a useful reference: it lists 300 mm of Z, workpieces of 760 x 460 x 275 mm and 500 kg, a best finish of 0.05 μm and a machine weight of 2400 kg. The FORM S on this page claims more on load and size, with 900 x 600 x 350 mm and 800 kg workpieces on a 600 x 400 mm table, but a coarser best finish of Ra 0.08 µm and a weight of 4,500 kg without dielectric. Those differences point to another generation or a different build, so the nameplate decides.
For precision work the listed figures are positioning accuracy of 2 µm with 50 nm resolution, adaptive gap control, and a C axis that is standard with full 360-degree rotation. Electrodes can weigh up to 100 kg. Twelve changer positions are enough for a roughing and finishing set on three or four small cavities.
Rapid traverse is 5,000 mm/min on X and Y and 8,000 mm/min on Z, the dielectric volume is 400 liters, and the control is AC FORM HMI.

Strengths & Limitations
Strengths
- 12-position ATC for unattended electrode changes
- Positioning accuracy of 2 µm with 50 nm resolution
- Workpieces up to 900 x 600 x 350 mm and 800 kg on a 600 x 400 mm table
- Standard C axis with full 360-degree rotation
- IPG generator at 120A peak with adaptive gap control
Limitations
- Best finish of Ra 0.08 µm is coarser than the 0.05 μm listed for the current AgieCharmilles FORM S 350
- Not a current GF listing, and the figures have not been matched to a GF product page
- 4,500 kg without dielectric needs a floor rated for it
- X and Y travels of 350 x 250 mm cover only part of a 900 x 600 mm workpiece in one setup

Frequently Asked Questions
01
The current AgieCharmilles FORM S 350 lists 350 x 250 x 300 mm travels, 760 x 460 x 275 mm and 500 kg workpieces, 0.05 μm best finish and 2400 kg machine weight. This page lists 350 mm of Z, 900 x 600 x 350 mm and 800 kg workpieces, Ra 0.08 µm and 4,500 kg.
02
Positioning accuracy of 2 µm and positioning resolution of 50 nm. The table does not say how the accuracy was measured or over what length, so ask for a recent calibration report when inspecting a used machine.
03
The listed ATC has 12 positions. Electrodes can weigh up to 100 kg by the head rating; the table gives no separate per-pocket limit for the changer, which is worth checking before loading heavy graphite.
04
Not in this unnumbered form. GF Machining Solutions currently lists the FORM S 350. The machine on this page is an older or differently configured FORM S, and its figures should be confirmed on the machine itself.
