The core principle of a sheet metal laser cutting machine is to focus a high-energy-density laser beam onto the material surface, melting or vaporizing the material through instantaneous high temperature. Simultaneously, high-pressure auxiliary gases (such as nitrogen or oxygen) are used to remove molten slag, achieving precise cutting. This process involves three key technologies:
Laser Generator: As the energy source, its power directly affects the cutting speed and thickness. Currently, most mainstream equipment uses fiber lasers, which feature high beam quality, low energy consumption, and long lifespan.
Optical Path Transmission System: This system precisely guides the laser beam to the cutting head through reflectors and focusing lenses, ensuring energy is concentrated in a tiny area, achieving millimeter-level precision.
CNC System: This system controls the laser head's movement trajectory through a preset program, and sensors monitor the cutting status in real time, automatically adjusting parameters to adapt to different materials.
