The laser cutter of the laser cutting machine can emit a high-power and density laser beam. This beam can quickly melt the metal plate when it is irradiated and use coaxial high-speed airflow to blow away the molten material on the surface of the cutting seam. The dimensional accuracy of laser cutting can reach ±0.05mm, and the surface roughness is only tens of microns. There is almost no change in the metal properties around the slit. Cutting metal plates with a thickness of 3cm can still ensure high accuracy. Laser cutting is suitable for processing metal sheet metal parts that are not suitable for making abrasive tools, such as sheet metal parts with complex outlines, small batches, and general thickness of 6~12mm, stainless steel patterns, marks, and fonts used in decoration, advertising, service industries, etc., as well as requirements Special parts for even cutting seams.
