Description
Fiber Laser Cutting Head

Fiber Laser Cutting Head, also known as a fiber laser cutting head, is a critical component of a Fiber Laser Cutting Machine. It is responsible for directing the laser beam from the source to the material surface for cutting. This cutting head is engineered to precisely focus the laser beam to a narrow point, enabling high-speed and high-quality material processing.
Key Components of a Fiber Laser Cutting Head
- Collimating Lens: Adjusts the laser beam emitted from the fiber to a parallel beam before it enters the focusing lens.
- Focusing Lens: Focuses the parallel beam into a small spot with high energy density, facilitating efficient material cutting.
- Nozzle: The orifice through which assist gas (e.g., nitrogen, oxygen, or air) is expelled along with the laser beam. This gas aids in ejecting 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, dynamically adjusting the height 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 damage.
Features of an Effective Fiber Laser Cutting Head
- High focusing accuracy.
- Support for auto-focus systems.
- Compatibility with high laser powers (e.g., 1kW, 6kW, 12kW, model dependent).
- Heat resistance and efficient cooling mechanisms.
- Versatility in supporting various assist gases.
Applications
