Key Features and Advantages
Dual Independent 5-Axis Machining Stations
At the heart of the GL.Ultra lies a twin-station architecture, with each side offering a full 5-axis configuration (X/Y/Z with dual rotary A/B or C). This enables:
- Complete independence in programming and operation
- Simultaneous or mirrored part machining
- Batch production or sample iteration within one cycle
- High-volume productivity in a reduced footprint
Ultrafast Laser Sources with Ultraprecise Beam Control
The GL.Ultra supports ultrashort pulse (USP) lasers, including femtosecond and picosecond sources. These are ideal for:
- Ablation without thermal damage (athermal material removal)
- Micron-scale structuring
- Burr-free edge quality and crack-free finishes
Laser source options can be individually configured per station, enabling one to run a femtosecond laser while the other uses a picosecond or CW source – giving unmatched flexibility.
Nanometric Accuracy with Granite Machine Bed
The system is built on a thermally stable granite machine bed, delivering:
- Vibration damping for sub-micron positioning
- Thermally stable micromachining over long operation cycles
- Low expansion coefficient for precise control
High-End Vision and Autofocus Systems
Each machining head is supported by integrated coaxial vision systems, allowing:
- Live workpiece inspection
- Precise alignment
- Automated focus tracking
This enhances the repeatability and reliability of laser drilling, cutting, or turning operations at micro scale.
