Description
Fiber Laser Cutting Head

The Fiber Laser Cutting Head is a critical component of a Fiber Laser Cutting Machine. It functions to direct the laser beam from the source onto the material surface for cutting. This cutting head is engineered for precise and narrow laser beam focusing, enabling high-quality and rapid material processing.
Key Components of the Fiber Laser Cutting Head
- Collimating Lens: Adjusts the laser beam emitted from the fiber into a parallel beam before it enters the focusing lens.
- Focusing Lens: Focuses the parallel beam into a small spot with high energy density for efficient material cutting.
- Nozzle: The aperture through which assist gases (e.g., nitrogen, oxygen, or air) are ejected along with the laser beam. This aids in expelling molten material from the cut kerf and ensures optimal cutting quality.
- Sensor / Auto-focus System: Measures the real-time distance between the cutting head and the material surface, automatically adjusting the height for optimal cutting performance.
- Cooling System: Due to the high energy of the laser beam, the cutting head incorporates a water or air cooling system to prevent thermal damage.
Features of a High-Performance Fiber Laser Cutting Head
- High focusing accuracy.
- Compatibility with auto-focus systems.
- Support for high laser powers (e.g., 1kW, 6kW, 12kW, depending on the model).
- Thermal resistance and efficient cooling system.
- Versatile compatibility with various assist gases.
