GF Machining Solutions AgieCharmilles CUT X 500

The CUT X 500 carries two independent wire spools and thread paths. In the cutting program, the programmer specifies which wire to use for each cutting pass — typically the coarser, faster wire for the main (roughing) cut and the finer wire for skim passes. When the program transitions between passes, the machine automatically retracts the active wire, threads the second wire through the workpiece start position, and continues cutting. The changeover takes approximately 30-60 seconds and requires no operator presence. This eliminates the manual wire changeover that single-wire machines require when switching between main cut and finishing wire, which typically takes 5-15 minutes of operator time per occurrence.

The most common twin-wire configuration is: Spool 1 — 0.30 mm zinc-coated speed wire (e.g., Bedra Cobra Cut) for the main roughing cut at maximum cutting speed; Spool 2 — 0.20 mm standard brass or diffusion-annealed wire for precision skim passes with better corner fidelity. Another common configuration: 0.25 mm standard brass for main cuts on most features, 0.15 mm fine wire for corners and detail features in the same program. For shops cutting carbide-tipped tooling, a third approach pairs a carbide-specific main cut parameter (low speed, stable conditions) with a fine finish wire for skim passes to achieve mirror-quality carbide surfaces.

Both are premium mid-size wire EDMs targeting precision die and mold work. The Sodick ALC600G Premium uses linear motors on all axes for zero-backlash positional accuracy that is maintained throughout the machine's life. The CUT X 500 counters with AI real-time discharge optimization and twin-wire capability — features Sodick's ALC600G does not offer. In terms of surface finish, both achieve Ra 0.08-0.10 µm. The Sodick's linear motor advantage is long-term positional accuracy maintenance; the CUT X 500's twin-wire advantage is workflow efficiency for shops that regularly switch wire sizes. Both price similarly at the premium end of the mid-size wire EDM market.

Yes. The CUT X 500 is designed for unattended overnight operation. AWT handles wire breaks and new-start threading automatically — AI guidance improves re-threading reliability on challenging geometries. The twin-wire system operates autonomously within a program, eliminating the need for operators during wire changeover. The AI discharge optimization reduces wire break frequency by adapting parameters before conditions become problematic. Many shops program complete multi-feature parts with main cuts on all features (Wire 1) followed by skim passes on all features (Wire 2) in a single unattended program, loading the workpiece at day's end and returning to a finished part.

The cycle time benefit of twin-wire varies by job complexity. For a simple profile requiring one main cut and two skim passes, the savings are modest — perhaps 10-15 minutes of eliminated manual changeover time. For a complex progressive die insert with 20+ punch openings, each requiring main cut plus skims, the savings compound: 20 manual wire changeovers at 10 minutes each is over 3 hours of operator time and machine downtime eliminated per part. On high-mix jobs where wire changes happen multiple times per program (different wire diameters for different feature types in the same workpiece), twin-wire delivers its greatest advantage — enabling single-program unattended completion of what would otherwise require multiple operator interruptions.
