What Is CNC Laser Cutting? Everything You Need To Know
Laser cutting was first used in the 1970s. In modern industrial production, laser cutting is widely applied to materials such as sheet metal, plastics, glass, ceramics, semiconductors, textiles, wood, and paper. In the coming years, laser cutting is expected to see significant growth in the fields of precision and micro-machining.
Understanding CNC Laser Cutting
CNC (Computer Numerical Control) laser cutting technology relies on a high power density laser beam that irradiates the surface of the material to be cut. This process melts, vaporizes, or ignites the material almost instantaneously. The molten or burnt material is then blown away through high-speed airflow, completing the cutting process.
