Application of laser cutting machine in cutting metal pipe

China is the world’s largest steel producer and consumer. In recent years, in order to meet the processing requirements of the industrial market, various tube laser cutting processing systems have come out one after another. With the rapid growth of metal pipe production and consumption, advanced laser processing system solutions have been widely used in the production and processing of the pipeline industry, especially the processing of stainless steel, alloy steel, silicon steel, galvanized steel, nickel-titanium alloy, and Inconel . Titanium alloy and other metal pipe processing applications.

At present, although pipe laser cutting equipment is rapidly popularized in China, the demand for CNC cutting talents and laser cutting technology is rapidly increasing. The severe shortage and lag of laser cutting equipment and CNC cutting talents and craftsmanship have led to low cutting efficiency, poor cutting quality, and serious waste of base metals. For the main technical issues of laser cutting, we have listed some of the main technical considerations in the pipeline industry for business owners’ reference.


For the full-stroke automatic laser cutting and blanking process requirements of large metal pipes, a unique dual-drive pneumatic chuck rotating mechanism is adopted in the mechanical structure. The pipe is cut through the movement of the machine tool and the workpiece is moved along the axis of the worktable at the same time. Full-stroke automatic laser cutting of large-length metal pipes.

CNC cutting

CNC cutting is a high-capacity, high-efficiency, and high-quality pipe cutting production method. The core of CNC cutting is the CNC cutting system. It is the cutting control software of the index control system, providing advanced cutting technology experience, so that the operator can cleverly use the control system to achieve high-quality, high-efficiency CNC cutting.

Nesting software
First, the computer is drawn, nested, cut and programmed in advance through professional pipe cutting software to generate a CNC cutting program, and then the full-length metal pipe is automatically laser-cut on the full-length. Professional pipe nesting software is the basis and prerequisite for realizing large-volume, high-efficiency and high-quality cutting and production of CNC pipe cutting machines.

Cutting process
When the pipe is cut (especially for small diameter pipes), the slag adheres to the inner wall of the pipe, and most of the heat generated by the cutting is absorbed by the workpiece. When the cutting density is high, it often leads to overheating of pipes and corners and square pipes. The burning of the corners seriously affected the cutting quality, and even failed to cut. Such problems can be used: keeping the focus of the cutting nozzle and the surface of the workpiece surface unchanged, so that the cutting effect is not affected by changes in the workpiece surface; increasing the oxygen pressure method; increasing the speed of the acute angle synthesis through software.

Now, the laser tube cutting technology is in the process of rapid development and continuous improvement. With the continuous update and development of computer technology, mechanical structure, cutting technology and optimization algorithms, CNC laser tube cutting technology will show its intelligence and speed more prominently. Optimized cutting process and technology provide technical support for high-efficiency cutting, high-quality cutting of laser pipe cutting machine, saving pipes and energy consumption.
