Principles and application fields of gantry laser cutting machine

　　As an advanced cutting equipment, the gantry laser cutting machine plays an important role in modern industrial production. With its efficient and precise cutting capabilities, it has brought significant production efficiency improvements to many industries.

　　1. Structure and working principle

　　The gantry laser cutting machine adopts the gantry structure, and the cutting workbench is separated from the main machine. This design allows the workbench to not affect the machine tool accuracy due to thermal deformation during the cutting process. Its working principle is to use the laser beam emitted from the laser generator to focus into a high-power density laser beam through the optical path system. When it is irradiated to the surface of the material, the material absorbs laser energy, the temperature rises sharply, and starts to vaporize and form holes after reaching the boiling point. As the high-pressure air flow moves with the relative position of the light beam and the workpiece, the material forms a slit. The laser can move with the gantry, breaking through the limitations of the laser cutting range of traditional flight optical paths.

　　2. Performance characteristics

　　Fast cutting speed and high efficiency: The gantry laser cutting machine is equipped with a mature laser CNC system, which can control the pressure, flow rate, etc. of the gas, speeding up processing efficiency. At the same time, it also has functions such as co-edge cutting, optimized nesting and discharge, efficient perforation, and sharp corner treatment, which further improves the cutting efficiency.

　　High cutting accuracy: The positioning accuracy and repeating positioning accuracy of this equipment can reach ±0.10mm, the cut quality is good, the verticality is about 1 degree, the surface is smooth, there is almost no scraping, and it has better weldability.

　　High material utilization: The plate-welded beam structure design is good, and it is not afraid of processing super large sheets, which can achieve material utilization.

　　Energy-saving and environmentally friendly: equipped with mature fiber lasers, good electro-optical conversion rate, no laser generation gas is required, and energy-saving and environmentally friendly. At the same time, a dust collection and treatment system can be configured to effectively reduce the hazards of cutting smoke and dust.

　　III. Application areas

　　Gantry laser cutting machines are widely used in the manufacturing industries of construction machinery, tower locomotives, shipbuilding, rail transit, etc., and are suitable for cutting metal materials such as stainless steel, carbon steel, alloy steel, and large processing ranges, such as 12m×3m, 15m×3.5m, 18m×4m, 24m×4.5m or larger. In the steel structure industry, for profile processing, gantry-type steel special cutting machines are more suitable for processing large-size steel, heavy-duty H-shaped steel, channel steel, angle steel, etc. for profile processing, and the beams are more balanced, cutting is more stable, and processing is longer lasting.

　　4. Development trends

　　With the continuous development of industrial technology, gantry laser cutting machines are also constantly innovating and upgrading. Develop towards higher precision, higher efficiency and more intelligent directions to meet the ever-changing industrial production needs. For example, some equipment already has three-dimensional five-axis technology to ensure cutting and further improve cutting flexibility and accuracy.
