The metal laser cutting machine has high efficiency. The high-density laser scans the surface materials. Thousands of thousands of degrees Celsius hot materials melt or evaporate the materials in a very short time, and then use high-pressure gas to blow and melt or evaporate the materials for cutting, so as to achieve the goal of cutting materials. For laser cutting, since the invisible beam replaces the traditional mechanical knife, the mechanical part of the laser head has no contact with the work, and the work surface will not produce scratches. Laser cutting speed is fast and the incision is smooth. The influence of cutting heat on this area is small, the plate deformation is small, and the cutting seam is narrow (0.1mm~0.3mm). No mechanical stress, no shearing burr. High precision, good repeatability, no damage to material surface; NC programming, can process any plane graphics, can cut large size plates, do not need mold, save time.
CNC plasma cutting machine is a kind of hot working equipment. Its working principle is to use the heat of high temperature plasma arc to melt the metal in the cutting part, and use the momentum of high-speed plasma to eliminate the molten metal forming the notch. The development of plasma cutting and the existing working gas have a significant impact on plasma arc cutting characteristics, cutting quality and cutting speed. The common working gases of plasma arc include argon, hydrogen, nitrogen, oxygen, air, water vapor and some mixed gases. Plasma cutting machine is widely used in automobile, locomotive, pressure vessel, chemical machinery, nuclear industry, general machinery, engineering machinery, steel structure and other industries. In terms of cutting accuracy, the plasma is about 1mm, and the laser can reach within 0.2mm. In cutting efficiency, laser is the combination of speed and effect. The cutting speed of 1 mm thick plate can reach 26 meters per minute.
