A high-intensity laser beam is generated internally by a fiber laser source and directed to the cutting head via a series of mirrors. The focused beam, typically only a few microns in diameter, heats, melts, and vaporizes the metal at the point of contact. A high-pressure assist gas stream (e.g., nitrogen for clean cuts or oxygen for thicker metals) coaxially blows away the molten material, leaving a clean, burr-free edge.
This non-contact, thermomechanical process ensures zero tool wear, minimizes material contamination, and delivers consistent, repeatable results in both small and large production runs.
