Due to the flexibility and efficiency of fiber laser cutting machine, conventional round hole cutting has also begun to be realized by fiber laser cutting machine. The finished products are not only smooth in cross section, but also the processing aperture can be flexibly changed to meet the diverse needs of the factory. However, processing round holes with laser cutting machines also requires some skills. Pay attention to the following matters to make the processing process smoother.

The air pressure is not suitable

During the air blowing process, when the air pressure is too low, edge scraping and carbonization will occur, and excessive pressure will easily cause holes to burst. Therefore, this requires the process proofer and the machine to cooperate perfectly, and choose the appropriate air pressure based on experience, so that the cut round holes are fuller.

The round hole is too small

The best solution for cutting round holes with a fiber laser cutting machine is a round hole ratio of 1:1, that is, the ratio of the aperture to the plate thickness is 1:1, that is, the larger the aperture, the easier it is to cut a high-quality round hole. Otherwise, when the fiber laser cutting machine has insufficient energy, it is easy to cut small holes with residual breakpoints and the phenomenon of the round hole being not round.

Servo motor parameters are incorrect

Circular holes sometimes appear elliptical or irregular, which is related to the mismatch of XY axis motion, and the direct cause of the mismatch of XY axis motion is the inappropriate adjustment of servo motor parameters. Therefore, the quality of cutting circular holes also has certain requirements for servo motors.

Guide rail and lead screw accuracy error

If the servo motor parameter error affects the cutting quality, then the guide rail and lead screw accuracy error will directly lead to the circular hole accuracy not meeting expectations. This is related to the strength of the fiber laser cutting machine manufacturer. Usually, some small factories will deceive customers that the fiber laser cutting machine accuracy can reach 0.1mm, but in fact, in the actual operation process, the quality and effect of laser drilling will be poor, affecting the added value of the product.

Therefore, REBOUND CNC recommends that when purchasing a fiber laser cutting machine, try to choose high-quality big brand products. Pay attention to whether the accuracy, speed and other parameters of the laser cutting machine for cutting circular holes meet the standard requirements to identify whether the quality of the purchased laser cutting machine is up to standard.
