Fiber laser cutting machine is widely used in the field of carbon steel processing due to its excellent performance such as fast, efficient, high quality and high yield. However, many users may encounter various problems during use due to lack of understanding of laser cutting machine, which affects the normal operation and cutting quality of fiber laser cutting machine. The following three common problems and corresponding solutions are analyzed for everyone.

When fiber laser cutting machine cuts carbon steel, burrs appear on the workpiece

Generally, the possible causes of burrs on the workpiece include:

(1) The laser focus position is offset. Perform a focus position test and adjust 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 is working normally. If it is normal, observe whether the output value of the laser control button is correct. If not, adjust it;

(3) The cutting line speed is too slow. It is necessary to increase the line speed during operation and control;

(4) The purity of the cutting gas is not enough. It is necessary to provide high-quality cutting working gas;

(5) The instability caused by the long-term operation of the machine tool requires shutdown and restart.

Incomplete laser cutting Reasons for incomplete laser cutting:

(1) The selection of the laser nozzle does not match the thickness of the processing plate, replace the nozzle or the processing plate;

(2) The laser cutting line speed is too fast, and the operation control needs to reduce the line speed.

Abnormal sparks when cutting low-carbon steel

When cutting low-carbon steel normally, the spark beam is long and flat, with less forking. Abnormal sparks will affect the smoothness and processing quality of the cut section of the workpiece.

At this time, if other parameters are normal, the following situations should be considered:

(1) The laser head nozzle is seriously worn out and the nozzle should be replaced in time;

(2) If there is no new nozzle to replace, the cutting working gas pressure should be increased;

(3) If the thread at the connection between the nozzle and the laser head is loose, the cutting should be stopped immediately, the laser head connection status should be checked, and the thread should be re-threaded.

Fiber laser cutting machines are expensive high-tech equipment. Once various problems occur during operation, it will not only consume effort but also increase costs. Therefore, it is best to choose good quality equipment when purchasing.
