Inquire

With the development of laser technology, fiber laser cutting machines for cutting round holes have been widely used by sheet metal laser processing manufacturers. As long as the fiber laser cutting machine can be operated, the round holes can be cut round and well. But why is the fiber laser cutting machine cutting round holes not round? How to solve this problem? Let's introduce Leapion laser.

Why doesn't the fiber laser cutting machine cut round holes? What are the solutions?

We analyze the reasons for the non-circular holes cut by the fiber laser cutting machine from the following points, and provide corresponding solutions:

1. Check the hardware of the fiber laser cutting machine: whether there is any problem with the beam, lens, nozzle, etc.

2. Check whether the servo motor of the fiber laser cutting machine or the fixing of the cutting head is loose.

3. Check whether the light intensity of the fiber laser cutting machine is adjusted properly, which causes the end of the sheet metal laser processing to not overlap. Generally speaking, the difference between the maximum light intensity and the minimum light intensity should not exceed 5%, and the speed should not be adjusted too much. Fast. If it is too fast, frames may be skipped, and the result will not overlap.

4. It may be that the blowing air pressure is not suitable

During the blowing process, when the air pressure is too low, slag scraping and carbonization will occur at the edge of the sheet metal laser processing, and the pressure is too high and it is easy to burst. Therefore, this requires the perfect cooperation between the sheet metal master and the fiber laser cutting machine, and select the appropriate air pressure based on experience to make the cut round hole more full.

5. Check whether the servo motor parameters are wrong

The round hole sometimes appears ellipse or irregular. This is related to the mismatch of the XY axis movement, and the direct cause of the XY axis movement is not adjusted properly. Therefore, the fiber laser cutting machine sheet metal laser processing round hole quality also has certain requirements for the servo motor.

6. It may be caused by the precision error of the guide rail and the lead screw

The precision error of the guide rail and the lead screw of the fiber laser cutting machine will directly cause the precision of the round hole to not reach the expected. This is related to the strength of the fiber laser cutting machine manufacturer. In the actual sheet metal laser processing process, 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 fiber laser cutting machines.

7. The circular hole cut by the fiber laser cutting machine is too small

The best solution for cutting round holes with fiber laser cutting machine is the round hole ratio 1:1, which means that the ratio of the aperture to the plate thickness is 1:1. Of course, this ratio, that is to say, the larger the aperture, the higher the quality of the cut Round holes are easier. Otherwise, when the energy of the fiber laser cutting machine is insufficient, the cutting holes are prone to residual broken points and out-of-round round holes.
