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.
