Fiber Laser Cutting Machine Working Principle
Laser:
Laser cutting machine uses a high-power laser (such as solid-state laser or CO2 laser) to generate a beam of high-energy laser
Focusing system:
The laser beam is focused by an optical device (such as a lens or a reflector) to concentrate the laser energy to a very small point, forming a high-energy density
Cutting head:
The cutting head contains a focusing lens and an air nozzle. The focusing lens focuses the laser beam into a fine and dense spot, while the air nozzle forms an airflow by injecting gas (usually nitrogen, oxygen or other auxiliary gas) to melt the metal in the cutting area
Cutting process:
The focused laser beam is irradiated onto the metal workpiece. The high-energy density spot heats the metal locally to the melting temperature, and the jet airflow blows away the molten metal to achieve cutting. The laser cutting machine performs a predetermined movement on the workpiece according to the required cutting path
Control system:
The laser cutting machine is equipped with a sophisticated motion control system and automation software to control the movement of the laser and cutting head, and control the laser power, speed and gas flow according to the set parameters to achieve the required cutting.
Advantages
High precision: Laser cutting can achieve very fine cutting, suitable for applications with complex shapes and high detail requirements.
Non-contact processing: Since it is non-contact processing, deformation of the material caused by mechanical stress is avoided.
Flexibility: The cutting path can be quickly adjusted to meet different design requirements.
Wide range of application: Almost all types of metals and some non-metallic materials can be processed.
Conclusion
Laser cutting machines occupy an important position in modern manufacturing with their high efficiency, precision and flexibility. Understanding their working principles and different cutting methods can help users better choose the processing solution that suits their needs. Whether in automobile manufacturing, aerospace or other industrial fields, laser cutting technology has shown great application potential.
