Fiber laser cutting machine has the advantages of high efficiency, high quality, high precision and intelligence, and is widely used in sheet metal processing. However, some problems will occur in the application process, especially when the customer does not have a professional laser cutting engineer, which will affect the normal operation of the machine and the quality of cutting carbon steel.
So what problems will we encounter during the operation? Let's take a look at it together.
1. Causes and solutions of burr in cutting carbon steel
1) If the laser focus position is offset, do the focus position test and adjust it according to the offset of the laser focus;
2) The output power of the laser is not enough. It is necessary to check whether the laser generator works normally. If it works normally, observe whether the output value of the laser control button is correct. If not, adjust it;
3) The cutting line speed is too slow, so it is necessary to increase the line speed during operation control;
4) The purity of cutting gas is not enough, so it is necessary to provide high-quality cutting gas;
5) The machine tool runs for a long time and is unstable. At this time, it needs to be shut down and restarted.
2. Reasons and solutions for incomplete cutting of carbon steel
1) If the selection of laser nozzle does not match the thickness of plate, replace the nozzle or plate;
2) The laser cutting line speed is too fast, so it is necessary to operate and control to reduce the line speed.
