Description
Fiber Laser Cutting Head

The 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 focus the laser beam to a narrow and precise point, enabling high-quality and rapid material processing.
Main Components of the Fiber Laser Cutting Head
- Collimating Lens: This lens adjusts the laser beam emitted from the fiber to a parallel beam before it enters the focusing lens.
- Focusing Lens: This lens concentrates the parallel beam into a small, high-energy-density spot, facilitating efficient material cutting.
- Nozzle: The nozzle directs the assist cutting gas (e.g., Nitrogen, Oxygen, or Air) along with the laser beam. This gas aids in expelling molten material from the cut kerf and helps control the cutting quality.
- Sensor or Auto-focus System: This system measures the real-time distance between the cutting head and the material surface, automatically 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 thermal damage.
Key Features of an Optimal 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).
- Thermal resistance and an efficient cooling system.
- Capability to work with various assist gases.
