Laser cutting has fast speed, narrow cutting seam, small heat affected zone, good perpendicularity of cutting seam edge, smooth cutting edge, and a wide variety of materials that can be laser cut, including carbon steel, stainless steel, alloy steel, wood, plastic, rubber, cloth, quartz, ceramics, glass, composite materials, etc. With the rapid development of market economy and the rapid advancement of science and technology, laser cutting technology has been widely applied in fields such as automobiles, machinery, electricity, hardware, and electrical appliances. In recent years, laser cutting technology has been developing at an unprecedented speed, growing at a rate of 15% to 20% annually. Since 1985, China has been growing at a rate of nearly 25% per year. At present, there is still a significant gap between the overall level of laser cutting technology in China and advanced countries. Therefore, laser cutting technology has broad development prospects and huge application space in the domestic market.
