Description
Fiber Laser Cutting Head
Fiber Laser Cutting Head is a critical component of Fiber Laser Cutting Machines.

Fiber Laser Cutting Head is a critical component of a Fiber Laser Cutting Machine. It is responsible for guiding the laser beam from the source to the material surface for cutting. This cutting head is engineered to focus the laser beam into a narrow and precise spot, enabling high-quality and rapid material processing.
Key Components of a Fiber Laser Cutting Head
- Collimating Lens: Adjusts the laser beam exiting the fiber into a parallel beam before it enters the focusing lens.
- Focusing Lens: Concentrates the parallel beam into a small spot with high energy density for efficient material cutting.
- Nozzle: The outlet through which assist cutting gas (e.g., Nitrogen, Oxygen, or Air) is expelled alongside the laser beam. This gas aids in clearing molten material from the cut kerf and controls cutting quality.
- Sensor or Auto-focus System: Continuously measures the distance between the cutting head and the material surface in real-time, adjusting the height to optimize 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.
Characteristics of a High-Quality 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.
- Versatility with various assist gases.
