GF Machining AgieCharmilles CUT 2000 OilTech

The GF Machining Solutions AgieCharmilles CUT 2000 OilTech is the oil-dielectric variant of GF's CUT 2000 series, purpose-built for the finest achievable surface finishes in wire EDM. By replacing the standard deionized water dielectric with hydrocarbon-based oil, the CUT 2000 OilTech achieves surface finishes down to Ra 0.05 µm — a true mirror-class result that sets the benchmark for surface quality in wire-cut EDM.

The physics behind oil-dielectric wire EDM are straightforward: oil produces smaller, more controlled spark discharges than water, resulting in shallower recast layers and finer surface textures. This makes the CUT 2000 OilTech the definitive choice for applications where surface finish is the single most important parameter — precision mold cavities that must achieve optical-grade surfaces, medical implant tooling where surface roughness directly affects biocompatibility, and watch component dies requiring mirror-polished wire-cut surfaces.

The machine shares the CUT 2000 platform's mechanical architecture: X/Y/Z travels of 350 x 250 x 256 mm, U/V travel of ±70 mm, and 200 kg workpiece capacity. Wire diameter support ranges from 0.10 to 0.30 mm standard, with optional micro-wire capability down to 0.05-0.07 mm. The IPG generator is configured with oil-specific discharge parameters optimized for the different dielectric properties of oil versus water.

A significant secondary benefit of oil-dielectric EDM is the elimination of workpiece corrosion. Water-based wire EDM can cause surface rust on steel and iron workpieces if parts remain in the tank after cutting. Oil dielectric eliminates this entirely, preserving pristine surfaces on hardened steel mold components throughout the cutting process and beyond.
