Fiber laser cutting machine is also called metal cutting machine, is one of the most efficient metal processing equipment, it is not only simple operation, cutting speed, high cutting accuracy, and environmental protection pollution-free. Fiber laser cutting machine not all materials can be cut, it can only process some conventional metal sheet, such as stainless steel, carbon steel, alloy steel, iron plate, copper, aluminum, titanium alloy and so on. Fiber laser cutting machine especially for the metal sheet below 16mm has obvious advantages, we take 500W fiber laser cutting machine as an example, cutting 3mm stainless steel speed can reach about 10 meters per minute, cut out of the product surface smooth without secondary polishing polishing processing. Fiber laser cutting machine is suitable for sheet metal processing, auto parts, metal crafts, cabinets, elevator manufacturing, kitchen and bathroom, machinery manufacturing, hardware products and other industries, has gradually replaced the traditional cutting equipment.
