Laser cutting is a non-contact processing method with highly concentrated energy, minimal heat transfer to the workpiece and an extremely small heat-affected zone. It can achieve micro-hole drilling and precision cutting of complex shapes, with burr-free cutting edges and excellent perpendicularity, enabling "one-time forming" and eliminating the need for subsequent grinding and trimming processes. The intelligent nesting software of laser cutting machines can automatically optimize the plate layout to maximize material utilization. Therefore, laser cutting effectively solves a series of problems such as low production efficiency, heavy reliance on labor, low processing precision, low plate utilization rate and serious environmental pollution.
