In order to strengthen everyone's understanding of the laser cutting machine, Longtai sorted out two common problems in sheet metal processing and provided solutions so that customers can adjust themselves when they encounter these problems in production.

Question 1: When cutting carbon steel, there are always burrs on the cutting surface?

Answer: As we all know, the working principle of laser cutting machine is to use laser energy to cut metal plates. Therefore, when there is a burr on the cutting surface of a sheet metal part, the first thing to consider is the position of the laser focus. If the position is not correct, it will lead to the inability to effectively process the sheet metal parts. Therefore, the solution is to adjust the focus orientation of the laser head. If there is no problem with the focus of the laser head, then the laser power needs to be considered. Since the cutting capabilities of lasers with different powers are different, if the thickness of carbon steel processed exceeds the extreme limit of laser cutting, the cutting quality will decline linearly. The third thing to check is the auxiliary gas. Generally speaking, only when the purity of the auxiliary gas is higher, the cutting performance of the laser cutting machine will be better. Therefore, the quality of the auxiliary gas should be guaranteed.

Second question: Why do you sometimes fail to cut through?

Answer: The main reason for unstable processing like this is that the nozzle of the laser head does not match the thickness of the processing material. Then the cutting line speed of the laser cutting machine is too fast, and the operation control is required to reduce the line speed; The deviation from the nozzle induction rejection to the laser focus area is large, so it is necessary to re detect the nozzle induction data, especially when cutting aluminum.
