Laser cutting machine is a new type of metal processing thermal cutting machine. It uses working gas and high-speed and high-temperature plasma arc as a heat source to partially melt the metal, and uses high-speed airflow to blow away the molten metal while forming a narrow plasma cutting seam. The tool is used to cut various metals, such as carbon steel, stainless steel, copper, aluminum, cast iron, etc. It not only has the advantages of narrow cutting seam, fast cutting speed, small heat-affected zone, smooth cutting, small deformation of the workpiece, simple operation, etc., but also has significant advantages and energy-saving effects. It is suitable for all kinds of machinery, metal structure manufacturing, repair and installation services, sheet metal manufacturing, drilling, excavation and repair, chamfering and more metal cutting projects and plans.
