Precision tool for modern industrial manufacturing of gantry laser cutting machine

　　As an important equipment in the field of industrial manufacturing, gantry laser cutting machines are widely used in metal processing, automobile manufacturing, aerospace, ship construction and other industries, becoming an important force in promoting the development of modern industry.

　　1. Technical principles and structural characteristics

　　The gantry laser cutting machine focuses on a laser, and uses an optical system to focus the high-energy laser beam into an extremely small spot, which irradiates to the surface of the material to quickly melt, vaporize or reach the ignition point. At the same time, the molten or vaporized metal is blown away with auxiliary gas coaxial to the beam, thereby achieving cutting. Its unique gantry structure separates the cutting workbench from the host, avoiding the problem that the workbench is affected by cutting thermal deformation, and the laser moves with the gantry, breaking through the limitations of the laser cutting range of the traditional flight optical path.

　　The equipment adopts overall welding of high-quality steel, heat treatment annealed and stress removal and precision processing, the longitudinal transmission adopts high-precision precision grinding guides, and the horizontal precision linear guides ensure the stability of the equipment operation and the accuracy of cutting. The bed processing adopts scientific process arrangement and high-precision processing methods. All processing surfaces are clamped in one piece, eliminating secondary clamping errors and ensuring the processing accuracy of the equipment.

　　2. Core advantages and application fields

　　Gantry laser cutting machine has many significant advantages. The cutting speed is fast and efficient, which can greatly shorten the production cycle; the cutting quality is good, the edges are smooth, the heat-affected area is small, and the material deformation is low; the cutting range of materials can be wide, including stainless steel, carbon steel and other metal materials.

　　In terms of application fields, in the machinery manufacturing industry, it can be used to cut various mechanical parts; in the shipbuilding field, it can efficiently handle the cutting needs of large plates; in the manufacturing of power towers and steel structures, it can easily deal with the processing of complex components; in the mining machinery industry, it can also achieve rapid and accurate cutting of heavy parts.

　　3. Intelligent and efficient development

　　Modern gantry laser cutting machines are constantly developing towards intelligence and efficiency. The mature laser CNC system can control the pressure, flow rate, etc. of the gas to speed up processing efficiency; it is equipped with intelligent programming software, which has functions such as co-edge cutting, optimized nesting and discharge, efficient perforation, sharp corner processing, and other functions. It also has the function of fine round hole cutting. Small hole cutting is completed in one go, without the need for drilling and reaming of the holes.

　　The industry's high-end longitudinal drive control system is controlled through the unique dual-drive shaft function, and the position signal feedback from the servo motor encoder is semi-closed-loop control, ensuring the long-term and stable operation accuracy of the gantry shaft, and can measure and display synchronization deviations in a timely manner. In addition, some equipment are also equipped with floating support devices, which can automatically absorb internal stresses caused by settlement of the foundation within the normal range and changes in ambient temperature, and improve the service life of the transmission.
