As we all know, with the emergence of laser cutting machines, traditional sheet metal punching methods have gradually been replaced. Because the processing section of the laser cutting machine is smooth, and the diameter can be changed at any time, the operation flexibility is high. However, the laser cutting machine sometimes cuts the round hole and sometimes it is not round. Is this a problem with the accuracy of the equipment or the process? How to solve the non-circular hole cut by the laser cutting machine? Leapion laser tells you below.
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 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.
1. It may be that the blowing air pressure is not suitable
During the blowing process, when the air pressure is too low, the edge scraping and carbonization will occur in the sheet metal laser processing. If the pressure is too high, it is easy to burst holes. 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.
2. Check whether the system parameters are wrong
The circular hole sometimes appears elliptical or irregular. This is related to the mismatch of the XY axis movement. The direct cause of the mismatch of the XY axis movement is the improper adjustment of the servo motor parameters. Therefore, the fiber laser cutting machine sheet metal laser processing round hole quality also has certain requirements for the servo motor.
3. 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.
4. 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 round hole ratio 1:1, which means that the ratio of aperture to plate thickness is 1:1. Of course, this ratio, which means that 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 small holes are prone to residual broken points and the round holes are not round.
Nowadays, using a laser cutting machine to make round holes in metal plates and metal tubes is a very common process in sheet metal laser processing. As long as the laser cutting machine is operated, the round hole can be cut round and well.
