Fiber Laser Cutting Machine : Accessories Selection Guide(2025)

Fiber Laser Cutting Machine is a device that uses laser technology to cut materials. It generates a high-energy-density laser beam through a laser generator, and focuses the laser beam on the surface of the material to be cut through an optical system, so that the material quickly absorbs the laser energy, and the temperature rises sharply to reach the melting point, boiling point or ignition point of the material, thereby melting, vaporizing or burning the material. At the same time, with the help of auxiliary gas coaxial with the laser beam, the molten material is blown away from the cutting area. As the cutting head moves along the preset path, the material is accurately cut. Fiber Laser Cutting Machine has the advantages of high cutting accuracy, good quality, fast speed, strong flexibility, and non-contact processing. It is widely used in metal processing, non-metal processing, advertising logo production, aerospace, shipbuilding and other fields, and can meet the diverse needs of different industries for material cutting.

Basic structure: The laser cutting head is usually composed of a focusing lens, a nozzle, a protective lens, a gas channel, a focusing tracking system and other parts. The focusing lens is used to focus the laser beam on the surface of the material to be cut to increase the energy density of the laser; the nozzle is used to spray auxiliary gas to help remove the slag and smoke generated during the cutting process and cool the cutting area; the protective lens is installed at the end of the cutting head close to the workpiece to prevent the spatter and dust during the cutting process from contaminating the focusing lens and other optical components; the gas channel provides a flow path for the auxiliary gas to ensure that the gas can be sprayed evenly; the focusing tracking system can adjust the distance between the cutting head and the workpiece in real time according to the fluctuations of the workpiece surface during the cutting process to ensure the accuracy of the focusing position.
Working principle: The laser cutting head uses the high energy density characteristics of the laser to focus the laser beam on the surface of the material through the focusing lens, so that the material quickly absorbs the energy of the laser, the temperature rises sharply, reaches the melting point or even the boiling point of the material, and the material quickly melts and vaporizes. At the same time, the auxiliary gas ejected from the nozzle blows the melted and vaporized material away from the cutting area to form a cutting seam, and finally the material is cut.
