Laser cutting machines are widely used in the field of carbon steel processing due to their excellent performance, such as fast, efficient, high-quality, and high-yield. However, due to the lack of understanding of laser cutting machines, many users may encounter various problems during use, which may affect the normal operation and cutting quality of carbon steel laser cutting machines. The following is an analysis of the following three common problems and the corresponding solutions for everyone.
When laser cutting carbon steel, there are burrs on the processed parts. The possible reasons include
(1) The laser focus position occurs Offset, do the focus position test, and adjust the sight according to the offset of the laser focus
(2) The output power of the laser is not enough, and the work of the laser generator needs to be checked Whether it is normal, if it is normal, observe whether the input value of the laser control button is correct, if it is not correct, adjust it
(3) The cutting speed is too steamy, it needs to be controlled during operation Increase the line speed
(4) The cutting gas purity is not enough, it is necessary to provide high-quality cutting working gas
(5 ) The instability of the machine running time is too long. At this time, it needs to be shut down and restarted.
2. If carbon The steel laser cutting machine is not completely cutting, and there is a reason why the laser is not completely cutting
(1) The choice of laser spray does not match the thickness of the processing board, replace the nozzle or processing board.
(2) The laser cutting line speed is too fast. Operational control is required to reduce the degree of remonstrance.
3. Abnormal sparks appear when the carbon steel laser cutting machine cuts low-carbon steel. When the low-carbon steel is cut normally, the sparks are long and flat, and there are fewer irregularities when opening. Normal sparks will affect the smoothness and processing quality of the cut section of the workpiece. At this time, when other parameters are normal, the following conditions should be considered:
Laser head nozzle If the loss is serious, the nozzle should be replaced in time
(2) When there is no new nozzle replacement, the cutting working gas pressure should be increased
(3) If the thread at the connection between the nozzle and the laser head is loose, you should immediately stop cutting at this time, check the connection status of the laser head and reinstall the thread. Laser cutting machine is a valuable high-tech equipment. Once various problems occur during operation, it will be laborious and costly. Therefore, when purchasing, choose a good quality carbon steel laser cutting machine.
