GF Machining MLTC

The GF Machining Solutions MLTC (Multi-Laser Tube Cutting) is a specialized femtosecond laser micromachining system purpose-built for manufacturing precision medical tubes, stents, and micro-components in a single setup. Unlike general-purpose laser texturing machines, the MLTC is engineered specifically for the medical device industry's demanding requirements for burr-free, heat-affected-zone-free cutting on thin-walled tubular components.

At the core of the MLTC is a 40 W femtosecond laser source that delivers clean material ablation through ultrashort pulse processing. The femtosecond pulse regime ensures zero heat-affected zones and burr-free cut edges — critical requirements for implantable medical devices where surface quality directly impacts biocompatibility and fatigue life. The system eliminates the need for secondary deburring operations that are common with conventional laser cutting systems.

The machine's granite-based mechanical structure provides exceptional thermal stability, while ironless linear motors and high-resolution glass scales deliver 1 µm positional repeatability across the 280 x 20 x 24 mm work envelope. The integrated 1,000 RPM spindle enables continuous rotation of tubular workpieces during cutting, allowing complex stent patterns and helical features to be produced in a single uninterrupted operation without consumables or dedicated tooling.

Compact at 1,600 x 2,000 x 2,000 mm and 2,300 kg, the MLTC fits into cleanroom and controlled production environments typical of medical device manufacturing facilities. Its single-setup capability — combining cutting, drilling, and surface modification on tubular components — reduces handling, fixturing, and potential contamination compared to multi-machine process chains.
