Description
Fiber Laser Cutting Head
The Fiber Laser Cutting Head, also known as a fiber laser cutting head, is a critical component of a Fiber Laser Cutting Machine. It functions to direct the laser beam from its source to the material surface for cutting. This cutting head is engineered to focus the laser beam into a narrow and precise spot, enabling rapid and high-quality 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: Focuses the parallel beam into a small spot with high energy density, facilitating efficient material cutting.
- Nozzle: Discharges assist gas (e.g., nitrogen, oxygen, or air) concurrently with the laser beam. This gas aids in blowing molten material away from the cut kerf and ensures optimal 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 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.
Characteristics of a High-Performance 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).
- Resistance to high temperatures and an efficient cooling system.
- Versatility for use with various assist gases.
