GF Machining CHARMILLES LASER S 2500 U fs

The GF Machining Solutions CHARMILLES LASER S 2500 U fs is the femtosecond-equipped variant of the largest LASER S platform. Built on the same 2,500 x 2,000 x 1,200 mm travel frame with 10,000 kg workpiece capacity, the fs model adds an ultrashort-pulsed femtosecond laser source for cold-ablation texturing that produces zero heat-affected zone on the workpiece surface.

Femtosecond laser pulses are shorter than the thermal diffusion time in the material, meaning each pulse ablates material without transferring heat to the surrounding area. This cold-ablation process preserves the metallurgical properties and surface integrity of the base material, which is critical for applications in medical, optical, and aerospace sectors where heat damage would compromise component performance.

The 5-axis configuration features a 240-degree laser head tilt (A-axis) and 370-degree rotary table (B-axis) for full access to complex 3D geometries. The 100W Femto IR FD source delivers industrial-grade femtosecond processing speeds. A dual-source configuration with both nanosecond and femtosecond lasers is available for shops requiring both production-rate texturing and precision cold ablation.

At 24,000 kg machine weight, the LASER S 2500 U fs requires a reinforced foundation and 7,125 x 6,304 mm installation space. Electrical supply is 40 kVA.

The fs variant targets the most demanding applications where the combination of large workpiece capacity and heat-free surface processing is required — primarily large medical implant tooling, optical mold inserts, and aerospace components where surface metallurgy must be preserved.
