Laser cutting technology has also evolved from the original flatbed cutting to today’s tube cutting.
The birth and application of professional laser tube cutting machines have greatly improved metal tube processing efficiency.
This article will explain the advantages of the professional tube and pipe laser cutting machines and the classification and characteristics of the mainstream professional laser tube and pipe cutting machines on the market today, and look forward to the development trend of professional laser tubes and pipe cutting machines.
The cutting principle of laser tube cutting machines and flat laser tube cutting machines is not much different. A laser tube cutting machine is used for standard metal tubes (round tubes, rectangular tubes, elliptical tubes, etc.), profiles (channel steel, angle steel, etc.), and some shaped tubes.
Compared to traditional processing techniques, it has the following advantages:
Thus, a professional laser tube cutter can replace mechanical drilling, milling, sawing, punching, or burr cleaning, which requires equipment and hard tools to process different metal tubes.
It can realize complex tube structure cutting, chamfering, slotting or hole cutting, scribing, and other possible size and shape features. A laser pipe cutting machine is very widely used. It is used in sheet metal processing, kitchenware, lighting, automotive, medical equipment, hardware, fitness equipment, and other industries.
Laser tube cutting machines can be broadly divided into two categories according to the axial feeding method of the tube.
This type of laser tube cutting machine only processes the fixed length of the tube, mostly used for processing axis constant, cross-sectional changes in the profile of the tube surface, the ends of the tube can not be processed.
Although fixed-length laser tube cutters have great limitations and low productivity, they occupy a large market share due to their special features.
Figure 1 shows the decorative patterns on the surface of lamp poles and lampshades processed by fixed material cutting laser tube cutting machine.
Working Principle
As shown in Figure 2, the fixed material cutting laser tube cutter consists of two clamping chucks, which hold the tube in place. The chucks make synchronous rotational movements around the tube axis, and the laser head makes axial. The radial feed cuts to the tube.
This type of tube laser cutting machine is mainly used to process the same section of the coaxial tube. It can process various contour shapes of the tube surface, but it can also be cut according to the design length of the tube part within the design stroke of the machine.
Compared with laser tube cutters for fixed material cutting, it has higher flexibility, scalability, and cutting efficiency and currently occupies most of the market share of professional laser tube cutters.
As shown in Figure 3, the feed-cut laser tube cutter can batch process standard metal tubes of various profiles such as square and round tubes and cut them.
Working principle
As shown in Figure 4, the tube is clamped by the clamping chuck, and the supporting chuck clamps the tube in the radial direction.
All chucks rotate around the tube axis in synchronous motion, the clamping chuck holds the tube for axial feeding, and the laser head feeds and cuts the tube in the radial direction.
At present, the feed cutting of laser tube cutting machine in the market mainly relies on two chucks, which is cost-effective, but its disadvantages are also obvious.
1) Poor stability of cutting accuracy
For parts too long or less rigid pipe, under the action of gravitational deformation plus chuck rotation centrifugal force, it is difficult to ensure the stability of cutting accuracy even if the support of servo roller or profiling wheel is added.
(2) Even though the laser head can cut through the supporting chucks, the chuck clamping end of the tail material cannot be cut, resulting in the waste pipe.
In response to these shortcomings, some equipment manufacturers have extended the design of a multi-chuck laser tube cutter based on the laser tube cutter with double-chuck feed cutting, as shown in Figure 5.
Among them.
This also explains why the multi-chuck feed cutting type laser tube cutting machine has not yet become a mainstream trend.
The future demand for tubes is getting bigger and bigger, and the processing requirements will be higher and higher. It is vital to improving processing accuracy and production efficiency for the rapid development of a professional laser tube cutting machine.
The needs of users evolve with time.
Modular design enables the addition or replacement of functional components to fulfill user needs and maximize both parties’ benefits.
Many users already have automatic loading and unloading equipment installed.
Automation’s advancement can effectively liberate workers and solve the problem of labor scarcity in businesses.
With the widespread adoption of the “Industry 4.0” idea and the maturation of 5G technology, the future laser pipe cutting machine will almost probably achieve complete automation.

In today’s advanced manufacturing landscape, the transformative potential of laser cutting has garnered significant attention. A technology once limited to specialized applications is now a cornerstone in myriad industries. Dive in to understand the many advantages of laser cutting and how it stands tall amongst other cutting methods like plasma cutting and waterjet cutting.
Laser cutting is a technology that uses a laser to slice materials. Essentially, a laser cutter focuses a high-powered laser onto a material’s surface. This concentrated energy source melts, burns, or vaporizes the material, leaving behind a precise and clean cut. Managed by computer programs, laser cutting offers unmatched precision and speed compared to traditional cutting methods.
Here’s an extensive exploration of the varied advantages laser cutting offers, setting it apart in the domain of metal fabrication and beyond.
At the heart of laser cutting’s appeal is its precision accuracy. Unlike other cutting methods, lasers provide pinpoint accuracy, ensuring parts and products adhere to strict tolerances. This precision is especially beneficial for industries where even a minor discrepancy can lead to significant quality issues. In comparison to plasma cutting or waterjet cutting, the laser cutting process stands out due to its meticulous attention to detail.
Moreover, the laser beam used in the cutting process is generated by computer programs. This computer-controlled aspect ensures that the process has minimal human intervention, and thus, the results are far more consistent. With laser cutting services being utilized by various manufacturing industries, the demand for such precision and consistency becomes more evident.
