Description
Fiber Laser Cutting Head

Fiber Laser Cutting Head is a critical component of Fiber Laser Cutting Machines. It directs the laser beam from the source to the material surface for cutting. This cutting head is engineered to precisely focus the laser beam to a narrow point, enabling high-speed, high-quality material processing.
Key Components of a Fiber Laser Cutting Head
- Collimating Lens: Adjusts the laser beam from the fiber source 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 for assist cutting gases (e.g., Nitrogen, Oxygen, or Air). It works in conjunction with the laser beam to eject molten material from the cut kerf and maintain cut quality.
- Sensor or Auto-focus System: Measures 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 thermal damage.
Characteristics 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 efficient cooling systems.
- Versatility for use with various gases.
