At present, the main problems and difficulties in the laser cutting process of pipe laser cutting machines are as follows: overburning of part cutting points, overburning of part corners, tilting of the cutting surface, and deformation or inability to close when cutting circular parts. This situation can directly lead to material waste and low production efficiency. And using advanced CNC systems can solve such problems. The so-called CNC pipe cutting technology refers to the advanced pipe cutting process and rich pipe cutting experience provided in the pipe cutting control software of the CNC system, enabling pipe cutting operators to achieve high-quality and efficient CNC cutting through proficient use of the control system. CNC laser pipe cutting technology is a large-scale, efficient, and high-quality cutting production method for pipes, and the core of CNC pipe cutting is the CNC pipe cutting system.
Due to the easy adhesion of slag to the inner wall of the pipe during processing, most of the heat generated during cutting is absorbed by the workpiece. When the cutting density is high, it often causes the pipe to overheat, and the corners and four corners of the square pipe to burn, seriously affecting the quality of the cut and even making it impossible to cut. For such issues, we can adopt:
1. Method of increasing oxygen pressure;
2. Improve the speed of sharp corner synthesis through software.
3. The cutting head of the pipe laser cutting machine is equipped with a height sensing servo system, which can ensure that the height between the nozzle and the surface plane of the workpiece remains unchanged (the focus remains unchanged) during the cutting process, so that the cutting effect is not affected by changes in the workpiece surface.
