Description
Fiber Laser Cutting Head

Fiber Laser Cutting Head is a critical component of a Fiber Laser Cutting Machine. It directs the laser beam from the source to the material surface for cutting operations. This cutting head is engineered to precisely focus the laser beam to a narrow point, enabling high-quality and rapid material processing.
Key Components of a 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: Concentrates the parallel beam into a small spot with high power density for efficient material cutting.
- Nozzle: Discharges assist gas (e.g., Nitrogen, Oxygen, or Air) along with the laser beam. This gas aids in expelling molten material from the cut kerf and ensures optimal cutting quality.
- Sensor/Auto-focus System: Continuously measures the distance between the cutting head and the material surface in real-time, adjusting the height to maintain optimal focus for superior 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 precision.
- Compatibility with auto-focus systems.
- Support for high laser powers (e.g., 1kW, 6kW, 12kW, depending on the model).
- Excellent heat resistance and efficient cooling mechanisms.
- Versatile compatibility with various assist gases.
