GF Machining Solutions AgieCharmilles CUT F 350

TCS is GF Machining Solutions' structural thermal monitoring and real-time compensation system for wire EDM. Temperature sensors distributed across the machine structure — including the column, work table, and guide head assemblies — continuously report temperature to the AC CUT control. When the system detects thermal expansion or contraction caused by ambient temperature changes or machine warm-up, it applies calculated positional offsets to the X, Y, U, and V axes to maintain programmed cutting positions. The practical result is consistent part dimensions from the first cut of the morning through a full production day, even in shops without precise climate control.

Both are well-regarded compact wire EDMs at similar price points. The CUT F 350's primary differentiator is its Thermal Compensation System — a more developed active thermal management approach than the FANUC C400iB offers. The FANUC C400iB counters with AI Pulse adaptive discharge control, which excels at wire-break prevention and unattended reliability. Surface finish and cutting accuracy are comparable between the two. The AC CUT control database and the FANUC 31i-WB are both mature, capable wire EDM controls — the choice often comes down to dealer support quality and control preference in a specific region.

The CUT F 350 accepts wire from 0.10 mm to 0.33 mm diameter. Standard production wire is 0.25 mm brass for general-purpose cutting and 0.30-0.33 mm for maximizing cutting speed on thicker sections. Zinc-coated brass wire (e.g., Bedra Cobra Cut) at 0.25-0.30 mm improves cutting speed 15-20% over standard brass. For fine-detail work requiring small internal corner radii — connector tooling, micro-mold inserts — 0.15 mm or 0.10 mm wire is appropriate, though cutting speed decreases proportionally. The AWT system is calibrated for each wire diameter and handles re-threading reliably across the full range.

Yes, the CUT F 350 operates in submerged mode — the workpiece is fully immersed in deionized water during cutting. Submerged operation improves flushing, reduces wire vibration, and enhances surface finish quality compared to flush-only cutting. The machine fills and drains the work tank automatically. Submerged cutting is the standard operating mode for precision wire EDM in a GF CUT machine; the dielectric system maintains deionized water conductivity and temperature within the ranges optimal for cutting.

Yes. The CUT F 350 is designed for unattended operation. The AWT system with broken-wire re-threading and hole-threading capability handles wire breaks and new-start threading automatically. The AC CUT control's technology database provides reliable cutting parameters that minimize wire breaks during unattended runs. Many shops run the CUT F 350 overnight on multi-feature parts, returning in the morning to finished workpieces. For maximum reliability in lights-out production, GF recommends a full wire spool sized to the job, dielectric water system in good condition, and cutting parameters selected from the technology database rather than custom-developed values.
