With the demand of production and processing, various technical products have also emerged, such as laser cutting machine has become a very good choice. Throughout the market today, there are still many kinds of laser cutting machines, and different models can produce different effects, so how to choose the laser cutting machine model? What should we pay attention to? Let’s take a look at the basic introduction.

There are many models of laser cutting machines. When purchasing, go to a more professional and reliable manufacturer. We can choose a professional manufacturer, which can provide a complete range of cutting machine models, and will also provide a detailed introduction of various cutting machine products of different models, analyze their basic power and use instructions, and so on. Of course, it can also provide the price details of different models of cutting machines. For the majority of purchasing friends, it is also easier to participate in the purchase and ensure their own practical benefits.

In addition, the choice of laser cutting machine model is mainly based on your own needs. The cutting machines needed in different fields are different, so we should have a certain understanding in the actual shopping life, and see which model of cutting machine can have better practical matching effect, so as to play a better effect. At the same time, it is also necessary to combine the price of the cutting machine to choose, so that we can have more practical benefits.

This is what we need to pay attention to and understand when choosing laser cutting machine. It is necessary for the majority of buyers to know well, so as to play a better production efficiency and improve value.

In recent years, with the continuous development of laser cutting machines, more and more enterprises have begun to use laser cutting machines to cut round holes. It not only cuts smooth sections, but also the aperture can be changed at any time, and the processing flexibility is very high. It is the best choice for cutting round holes.

Due to the flexibility and efficiency of laser cutting, the conventional round hole cutting is also started to be realized by using optical fiber laser cutting machine. The finished cutting products not only have smooth section, but also can be flexibly changed to meet the diversified needs of the factory. However, laser cutting of circular holes is not as simple as you think. Irregular and insufficient verticality of the circular holes are also common. So Xinquanli laser professional technicians will analyze the reasons and precautions for you.

What if the round hole is too small? The scheme of laser cutting machine cutting round holes is that the ratio of round holes is 1:1, that is, the ratio of hole diameter to plate thickness is 1:1, that is, the larger the hole diameter, the easier it is to cut high-quality round holes. Therefore, the quality of cutting round holes also has certain requirements for servo motors. Sometimes the round hole may appear elliptical or irregular, which is related to the X  Y axis motion mismatch, and the direct cause of the X  Y axis motion mismatch is the improper adjustment of servo motor parameters. Otherwise, when the energy of the fiber laser cutting machine is insufficient, it is easy to cut small holes with residual breakpoints and round holes.

During the blowing process, when the pressure is too low, the edge scraping and carbonization will occur, and the hole is easy to burst when the pressure is too high. Therefore, this requires the process proofing engineer to cooperate with the machine and select the appropriate air pressure based on experience, so as to make the cut round hole fuller.

If the parameter error of servo motor affects the cutting quality, the accuracy error of guide rail and lead screw will also directly lead to the round hole accuracy not meeting the expectation. This is related to the strength of laser cutting machine manufacturers. Therefore, Xinquanli Laser recommends that in the process of purchasing laser cutting machines, we should try to choose high-quality products of large brands. Pay attention to whether the accuracy, speed and other parameters of the laser cutting machine cutting round holes meet the standard requirements to identify whether the purchased laser cutting machine is qualified.

The laser cutting machine has the advantages of high cutting accuracy, fast speed, free from cutting pattern restrictions, low processing cost, etc. The laser cutting has no burr, wrinkle and high accuracy. It is gradually replacing the traditional metal cutting process equipment, and the workpiece material has a certain impact on the laser cutting accuracy. In the same case, the cutting accuracy of stainless steel is higher than that of aluminum, and the cutting surface is also smoother. At present, laser cutting machines are more and more widely used.

In fact, the cutting accuracy of the laser cutting machine does not depend entirely on the equipment itself, but is affected by many factors. In the parallel compensation mechanism, there is a beam self-adjusting plate, which plays a transitional role between the auxiliary beam driving structure and the beam, so that the beam can realize the high-precision drive in the X-direction under the driving effect of the main and auxiliary drives, It also makes automatic compensation when the displacement between the beam and the bed changes between the motion and the drive under the influence of various factors.

Optical fiber laser cutting machine The size of the laser beam after focusing in the new industry of kitchen utensils processing. The smaller the laser beam after gathering, the higher the cutting accuracy. As for the understanding of laser cutting accuracy, many people have some misunderstandings. The core of synchronous compensation technology is the bilateral drive of the beam with automatic compensation mechanism. The main and auxiliary guide rails are driven by servo motors and driven by high-precision gear and rack, with high accuracy, large driving torque, fast response speed and good synchronization performance.

The greater the thickness of the workpiece, the lower the accuracy, and the larger the cutting seam. Because the laser beam is conical, the cutting seam is also conical. It is also stainless steel. The cutting seam of 0.3mm stainless steel is much smaller than that of 2mm stainless steel. A moderate increase in cutting speed can improve the quality of the cut, that is, the cut is slightly narrowed, the cut surface is smoother, and the deformation can be reduced.

The selection of cutting speed of laser cutting machine is also very important. The range of cutting speed can be selected according to the equipment description or determined by test. Due to the thickness of materials, different materials, different melting points, thermal conductivity and surface tension after melting, the cutting speed also changes accordingly.

With the change of industrial production demand, laser cutting as a processing method has been accepted by more and more sheet metal producers. In the whole plate processing of domestic steel, the phenomenon of poor processing in local areas often occurs. Laser cutting machine is regarded as an important means to promote the upgrading of traditional industries, but it still faces the huge bottleneck of insufficient application and backward core technology.

Especially in the process of cutting thick metal plates, the cutting speed will drop significantly, and the repeatability of the incision is poor, which makes it impossible to compete with traditional technologies. This phenomenon is sometimes very random, even when the processing machine is in good condition, which greatly affects the whole work progress in order to deal with local faulty products. If the laser cutting machine can overcome the difficulties in the thick plate cutting process, it will undoubtedly have a greater market prospect.

The cutting section is often encountered when processing medium and thick plates. Such cutting is not only questioned about the quality of the finished products, but also accompanied by excessive burning and serious slag, so that it does not reflect the value of the high-priced laser processing machine from other cutting methods. However, if a small power pulse is used for piercing, the time will be very long (12 seconds), which will lead to the reduction of cutting efficiency and unit cost

Improvement.

Piercing time accounts for a large proportion in thick plate processing, and various laser manufacturers have developed rapid piercing technology. The most representative is high-energy piercing, which has the advantage of high speed. However, the defect is that the huge energy injected during piercing makes the temperature of the plate rise and affect the subsequent overall cutting process, and affects the processing of small shapes.

For carbon steel, the important factor to improve the cutting section is to control the heat input to the plate and ensure the full combustion of the laser irradiated part. For stainless steel, the important factors to improve the cutting section are the improvement of the beam (improving the focal depth) and the effective use of auxiliary gas. The bright cutting technology is the result of improving the vibration generator and nozzle. Gu Ming’s idea of peak perforation is to use the peak value pulse laser with a small duty cycle, supplemented by non-fuel sprayed on the surface of the material to remove the attachment at the edge of the opening, and control the reasonable frequency of the pulse while cooling and piercing.

At present, in order to improve the operating speed of the processing machine, the metal laser cutting machine mostly adopts the structure commonly known as the flying light path, that is, the material tray does not move while the processing head moves in the whole machinable area. It is characterized by relatively long hole blasting time of 3 seconds, but small hole diameter (about φ 4mm) and there is no attachment at the edge of the opening and the heat input is low, which is convenient for the next normal cutting

The cutting efficiency is 4 times higher than that of ordinary piercing.

Although the structure of this method is simple, it will change the depth of focus, making it difficult to cut the medium and thick plate which is extremely sensitive to the depth of focus. The use of equal-length optical path can avoid the change of focal depth, so that the spot and focal depth are consistent. In addition, the importance of heat input can control the heat accumulated in the plate, and solve the stability problem better. In order to compensate the phase between the processing head and the light source

For the change of position, manufacturers also try to ensure the consistency of light spot within the processing range, and the use of curvature variable refractors is the common choice.

With the innovation of laser technology, the laser power applied to industrial production will also continue to grow. In the future, the metal laser cutting machine will break through the existing cutting thickness limit step by step, bringing more surprises to industrial production.
