Automatic CNC Pipe/Tube Cutting Machine
CNC tube cutting technology
CNC tube cutting is a large-scale, high-efficiency and high-quality pipe cutting production method, with CNC cutting system as its core. At present, the quality problems existing in the laser tube cutting process such as overburning of the cutting point and corners of the part, inclined cutting surface, and deformation or inability to close when cutting round parts directly lead to serious waste of the tube and low cutting production efficiency.
CNC tube cutting technology is the cutting control software of the index control system that provides advanced cutting technology and rich cutting experience, so that cutting operators can achieve high-quality and high-efficiency CNC cutting through the proficient use of the control system.
Professional CNC tube cutting and nesting technology
Due to the high cutting efficiency of CNC tube cutting technology, programming nesting is more complicated. If used improperly, it will cause pipe waste and low cutting efficiency. We use professional pipe cutting and nesting software to pre-program drawing, nesting, and blanking on the computer to generate NC cutting programs, and then perform full-stroke automated laser cutting and blanking of large-length metal pipes. Professional pipe nesting software is the basis and prerequisite for realizing large-volume, high-efficiency and high-quality cutting production of CNC pipe cutting machines.
CNC tube cutting process
When the pipe is cut (especially for the square pipe with small pipe diameter), the molten slag adheres to the inner wall of the pipe, and most of the heat generated by the cutting is absorbed by the workpiece. High cutting density will lead to the overheat of the pipe and the overburning of corners and square pipes, seriously affecting the quality of the incision.
In order to slove such problems, you can try:
(1) The laser cutting head with a height sensing follow-up system can ensure that the height of the cutting nozzle and the surface of the workpiece remains unchanged (the focus remains unchanged) during the cutting process, so that the cutting effect will not be affected by the change of the workpiece surface;
(2) The method of increasing the oxygen pressure (6-8Mpa);
(3) Improve sharp corner synthesis speed through software.
The above method can solve the problems of overburning and slagging in CNC pipe cutting.
