More and more companies begin to use laser cutting round holes because of the flexibility and efficiency of laser processing methods. The 1000W fiber laser cutting machine’s air travel speed of 90 meters per minute is sufficient to meet the high-speed requirements of many sheet metal processing plants. In addition, the laser process the section of the circular hole smoother, and the diameter of the circular hole infinitely modified to meet the diverse needs of factories.
However, machining round holes with a laser cutting machine is not very simple, but requires some skill. Let the laser engineers analyze the reasons and precautions for cutting round holes.
The blowing pressure is not suitable
During the blowing process, when the air pressure is too low, edge scraping and carbonization will occur. If the pressure is too high, it is easy to burst holes. So this requires the craftsman and the machine to cooperate perfectly, and choose the right air pressure based on experience to make the round hole more circle.
The hole is too small
The best solution for laser cutting machine to cut round holes is a round hole ratio of 1:1, which means that the ratio of aperture to plate thickness is 1:1. Of course, this ratio means that the larger the aperture, the higher the quality of the circle. Hole is easier. Otherwise, when the energy of the fiber laser cutting machine is insufficient, the small holes are prone to residual broken points and the round holes are not round.
Servo motor parameters are wrong
The circular hole sometimes appears elliptical or irregular. This is related to the X\Y axis movement mismatch, and the direct cause of the X\Y axis movement mismatch is the improper adjustment of the servo motor parameters. Therefore, the quality of cutting round holes also has certain requirements for the servo motor.
The precision error of the guide rail and the screw caused
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 accuracy of the round hole to not reach the expected. In actual operation, the quality and effect of laser drilling will be poor, which will affect the added value of the product. Therefore, it is very necessary to choose high-quality and large-brand laser cutting machines.
All these parameters are used to identify whether the precision, speed, and other parameters of cutting round holes meet the standard requirements, and they are sufficient to identify whether the quality of the laser cutting machine purchased is satisfactory.
