Fiber Laser Cutting Head
The Fiber Laser Cutting Head is a critical component of Fiber Laser Cutting Machines. Its function is to direct 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 spot, enabling high-quality and rapid material processing.
Key Components of a Fiber Laser Cutting Head
- Collimating Lens: This lens is responsible for making the laser beam, emitted from the fiber, parallel 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 is the aperture through which assist gas (such as nitrogen, oxygen, or air) is expelled along with the laser beam. This gas helps to remove molten material from the cut kerf and ensures optimal cutting quality.
- Sensor / Auto-focus System: This system measures the real-time distance between the cutting head and the material surface, automatically adjusting its position to achieve the best cutting results.
- 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-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).
- Excellent thermal resistance and an efficient cooling system.
- Versatility for use with various assist gases.
