In recent years, with the continuous development of laser cutting machines, more and more enterprises begin to use laser cutting machines to cut round holes. It can not only cut a smooth section, but also change the aperture at any time. It has high machining flexibility and is the only choice for cutting round holes.

Due to the flexibility and efficiency of laser cutting, the traditional round hole cutting has begun to be realized by optical fiber laser cutting machine. The cut finished product not only has a 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 we imagine. Irregularities and lack of perpendicularity of circular holes also occur from time to time. Therefore, Chuyu's professional technicians will analyze the causes and preventive measures.

What if the round hole is too small? The best method for laser cutting machine to cut round holes is that the ratio of round holes is 1:1, that is, the ratio of aperture to plate thickness is 1:1, that is, the larger the aperture, the easier it is to cut high-quality round holes. Therefore, the cutting quality of round holes has certain requirements for servo motors.

How does the laser cutter cut round holes?

Sometimes, ellipses or irregular shapes will appear in the circular hole, which is related to the mismatch of x axis and y axis motion. The direct reason for the mismatch between the x axis and y axis is the improper adjustment of the servo motor parameters. Otherwise, when the energy of the optical fiber laser cutting machine is insufficient, the cutting hole is easy to leave some breakpoint residues, and the round hole is not round.

In the blowing process, too low air pressure will lead to slag scraping and edge carbonization, and too high pressure is easy to burst holes. Therefore, it is required that the proofing machine should be perfectly matched with the machine, and appropriate air pressure should be selected according to experience to make the round hole cut fuller.

If the parameter error of the servo motor affects the cutting quality, the accuracy error of the guide rail and the lead screw will directly cause the hole accuracy to fail to reach the expected level. This relates to the strength of laser cutting machine manufacturers.

Therefore, Chuyu Laser suggested that in the process of purchasing laser cutting machines, we should try our best to choose high-quality and big brand products. Pay attention to whether the accuracy, speed and other parameters of the laser cutting machine for cutting round holes meet the standard requirements to confirm whether the quality of the purchased laser cutting machine is qualified.
