With the application of laser cutting machine, customers can easily cut round holes with laser cutting machine. Laser cutting machine has become the best choice for cutting round holes with its obvious advantages such as smooth section, changeable aperture and flexible processing.
In fact, cutting round holes with laser cutting machine is not as easy as expected. Now let's talk about the points needing attention when cutting round holes with laser cutting machine?
First point: the blowing pressure is not suitable
During the blowing process, when the air pressure is too small, there will be slag scraping and carbonization at the edge, and if the pressure is too large, it is easy to burst the hole. Therefore, it requires the perfect cooperation between the process proofer and the machine, and choose the appropriate air pressure based on experience, so as to make the cut round hole fuller.
Second point: the round hole is too small
The best scheme 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 to say, the larger the aperture, the easier it is to cut high-quality round holes. Otherwise, when the energy of the fiber laser cutting machine is insufficient, the cutting hole is prone to point breakpoint residue and the round hole is not round.
Third point: servo motor parameters are incorrect
The round hole sometimes appears ellipse or irregularity, which is related to the mismatching of x\y axis movement, and the direct cause of the mismatching of x\y axis movement is the improper adjustment of servo motor parameters. Therefore, the quality of cutting round holes also has certain requirements for servo motors.
Fourth point: the accuracy error of guide rail and lead screw leads to
If the parameter error of servo motor affects the cutting quality, the accuracy error of guide rail and lead screw will directly lead to the round hole accuracy not reaching the expectation.
This is related to the strength of laser cutting machine manufacturers. Usually, some small factories will cheat customers that the precision of laser cutting machine 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 products.
