GF AgieCharmilles Form S 1000

The GF AgieCharmilles Form S 1000 is one of the largest sinker EDM machines in GF Machining Solutions' portfolio, designed to meet the demands of the heaviest die and mold work in automotive, aerospace, and energy sectors. With a full meter of X-axis travel and a worktable capable of supporting multi-ton tooling blocks, the Form S 1000 represents the top of GF's sinker EDM lineup for shops that regularly machine large stampings dies, automotive body panel molds, large forging dies, and oversized die casting tooling.

At the core of the Form S 1000 is GF AgieCharmilles' top-tier ISPG (Intelligent Speed Power Generator) system, configured for high-current roughing capability without sacrificing the fine-finishing modes needed to complete cavities to specification in a single setup. The generator delivers up to 160A peak current for aggressive material removal in large electrode plunge operations, while the same generator platform steps down smoothly to the ultra-fine discharge conditions needed to achieve mirror finishes in finishing passes. This single-machine capability eliminates the need to transfer work between roughing and finishing EDM machines, saving setup time and maintaining positioning consistency.

The Form S 1000's HMI is GF Machining Solutions' current-generation touchscreen control with full iQ technology integration. iSpark technology handles real-time gap monitoring and adaptive spark control; iExpert provides an extensive machining condition database covering the full range of electrode and workpiece material combinations encountered in large die and mold work; and iCoach guides operators through setup and first-article qualification procedures. The control also integrates with GF's digital manufacturing connectivity tools for remote monitoring, process data logging, and OEE tracking — capabilities that large production die shops increasingly require for process documentation and continuous improvement.

Handling workpieces that can weigh several tons requires a machine structure of exceptional rigidity. The Form S 1000 is built on a heavy cast iron base and column with a robust C-frame or traveling-column architecture (depending on variant) designed to maintain geometric accuracy under maximum table load. The work tank is engineered with adequate volume for deep immersion of large workpieces, and the dielectric fluid system is scaled to the machine's size with high-capacity filtration and precise temperature regulation. Thermal growth compensation is applied to maintain cavity position accuracy across the multi-hour or multi-day cycles common in large die work.

For shops operating large-scale automated manufacturing cells, the Form S 1000 supports integration with GF Machining Solutions' automation products and System 3R tooling for electrode management. While full robot integration at this machine size requires custom cell engineering, GF's applications team supports the design and commissioning of automated cell configurations. The machine's scale makes it a significant capital investment, but for shops whose business depends on large-format precision die and mold work, the Form S 1000 is a machine that can anchor a competitive large-die machining capability.
