Description
Fiber Laser Cutting Head

Fiber Laser Cutting Head, also known as a fiber laser cutter 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 focus the laser beam into a narrow and precise point, enabling high-speed and high-quality material processing.
Key Components of the Fiber Laser Cutting Head
- Collimating Lens
Adjusts the laser beam exiting 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 for efficient material cutting. - Nozzle
Discharges assist gas (e.g., Nitrogen, Oxygen, or Air) along with the laser beam. This gas helps expel molten material from the cut kerf and maintains cutting quality. - Sensor or Auto-focus System
Monitors 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 damage.
Features of a High-Quality Fiber Laser Cutting Head
- High focusing accuracy.
- Compatibility with auto-focus systems.
- Support for high laser power (e.g., 1kW, 6kW, 12kW, depending on the model).
- Heat resistance and an efficient cooling system.
- Versatility to work with various assist gases.
