Overview
The AgieCharmilles Form X 400 is a CNC sinker EDM from GF Machining Solutions (formerly Agie-Charmilles), designed as a high-productivity automation-ready machine for die and mold production. The Form X 400 combines GF's AC FORM generator technology with a large 560x400 mm work tank and an integrated System 3R or Erowa-compatible electrode magazine for lights-out electrode management. The Form X designation indicates the machine is optimized for integration with GF Machining Solutions' 3R WorkShopManager software, enabling automated scheduling of electrode burns across multiple machines in a connected mold shop cell. The Form X 400 achieves Ra 0.1 micron surface finish in mirror-quality finishing conditions, making it suitable for optical mold surfaces and high-polish cosmetic part cavities. With an integrated C-axis rotary unit, the machine burns helical features and complex asymmetric profiles in a single workholding. GF Machining Solutions' iGEN4 intelligent generator monitors spark conditions in real time, automatically adapting discharge parameters to maintain efficient erosion as cavity geometry changes.

Strengths & Limitations
Strengths
- iGEN4 adaptive generator provides industry-leading electrode wear reduction
- Ra 0.1 micron mirror finish for optical mold and cosmetic cavity surfaces
- 60-position electrode magazine enables fully unattended multi-cavity programs
- 3R WorkShopManager integration for multi-machine cell scheduling
- C-axis standard enables helical and asymmetric feature burning without repositioning
Limitations
- Very high capital cost requires high-value mold work to justify
- 60-position electrode magazine adds footprint and setup complexity
- iGEN4 adaptive control most beneficial with complex cavity shapes — less advantage on simple burns
- 3R WorkShopManager requires investment in pallet infrastructure and software licenses

Frequently Asked Questions
01
The Form X series is designed for automation cell integration with System 3R / Erowa electrode magazines and WorkShopManager scheduling software. The Form P series is a more standalone machine. Both share the AC FORM generator but the Form X has deeper automation connectivity.
02
Yes. The C-axis rotary unit is standard on the Form X 400, providing continuous rotation of the workpiece (or electrode) during the burn for helical features, thread EDM, and complex rotational profiles.
03
Graphite electrodes benefit most from iGEN4's low-wear technology. The generator detects electrode-to-workpiece contact conditions and adjusts spark energy to minimize graphite wear, significantly extending electrode life on deep-cavity burns.
