In the field of metal manufacturing, fiber laser cutting machines have almost become an indispensable tool in all processing workshops. The application of laser metal cutting machines makes metal manufacturing projects more convenient and efficient. Maybe you are owning a fiber laser cutting equipment, so do you know how it completes metal cutting work? This post introduces you to the working principle of fiber laser cutting machine.

 

Fiber laser cutting machine is to focus the laser light emitted from the laser into a high power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point, and the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material will eventually form a slit, so as to achieve the purpose of cutting.

 

In the process of laser cutting metal, different auxiliary gases play different roles. Oxygen can assist combustion, and the heat generated can promote metal processing. Nitrogen can push the molten metal irradiated by the laser beam from the upper part of the kerf to the lower part, and then remove it from the back of the processing to prevent dross on the back. High-speed gas can assist in expelling molten metal.

 

The advantages of laser cutting technology also make the fiber laser metal cutting machine widely used in the advertising industry, handicrafts, construction industry, hardware industry, kitchenware manufacturing and other machinery manufacturing and processing industries.
