The sheet and tube laser cutting machines can cut metal plates and tubes at the same time with high efficiency and precision. It adopts non-contact way and a high-power laser beam to cut tubes and plates quickly in order to ensure accurate cutting trajectory through a precise control system. The sheet and tube laser cutting machines not only has high cutting speed and excellent cutting quality, but also can easily deal with the cutting processing of various complex shapes and sizes of tubes and plates. Its integrated design makes the tube and plate cutting process more smooth and efficient, greatly improving productivity. The sheet and tube laser cutting machines are widely used in metal processing, automobile manufacturing, machinery manufacturing and other industries.
