Fiber laser cutting machine is used for cutting carbon steel, with fast speed and high efficiency. Carbon steel has good absorption effect on laser and good cutting quality. Carbon steel, as a high-quality alloy steel, has been widely used in daily life and industrial fields due to its excellent structural properties. Due to the presence of carbon in carbon steel, the reflection of light is not strong and the absorption of light beams is also very effective. Carbon steel is more suitable for cutting with laser cutting machines. The processing effect is also very good. The cutting surface is flat, smooth, and aesthetically pleasing. Cost.
Fiber laser cutting machines are mainly used for laser cutting of carbon steel materials. However, due to the high hardness of carbon steel, long-term inspection and maintenance of fiber optic equipment are necessary to avoid problems. If there are problems during the processing, it is necessary to inspect all aspects of the laser cutting machine.
Unusual sparks during laser cutting of low-carbon steel:
When laser cutting low-carbon steel normally, the spark beam is long and flat with few forks. Abnormal sparks can affect the flatness and machining quality of the workpiece cutting section. At this point, when other parameters are normal, the following situations should be considered:
1. The laser head nozzle is severely worn and should be replaced in a timely manner.
2. Without replacing the new nozzle, the pressure of the cutting working gas should be increased.
3. If the thread at the connection between the nozzle and the laser head is loose, cutting should be stopped immediately, the connection status of the laser head should be checked, and the thread should be reinstalled.
4. Reasons for incomplete laser cutting:
5. The selection of laser nozzle does not match the thickness of the processing board. Replace the nozzle or processing board.
6. The laser cutting line speed is too fast and requires operation control to reduce the line speed.
7. What problems may occur with the carbon steel material of the laser cutting machine.
8. When laser cutting carbon steel, the hair on the workpiece generally causes burrs on the workpiece. Possible reasons include:
9. Move the laser focus position, conduct a focus position test, and adjust it according to the displacement of the laser focus.
10. The output power of the laser is insufficient. It is necessary to check if the laser generator is working properly. If normal, observe whether the output value of the laser control button is correct. If not, adjust it.
11. The cutting line speed is too slow, it is necessary to increase the line speed during the operation control process.
12. The purity of cutting gas is not enough, and high-quality cutting working gas must be provided.
13. The machine tool is unstable due to long running time and needs to be stopped and restarted.
