Common Problems and Practical Solutions of Laser Cutting

Laser cutting machine has been widely used in the field of carbon steel processing because of its fast, efficient, high quality, high income and other excellent performance. However, many users lack the understanding of laser cutting machine, so in the process of using, they may encounter various problems, which affect the normal operation of laser cutting machine and cutting quality. The following three common problems and corresponding solutions are analyzed for you.

1. Burrs appear in the workpiece when laser cutting carbon steel

Generally, burrs occur on workpieces. Possible causes include:

(1) The laser focus position is offset, and the laser focus position is measured and adjusted 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 properly. If it works properly, the output value of the laser control button is observed whether it is correct or not, if it is not correctly adjusted.

(3) The cutting speed is too slow, so it is necessary to increase the cutting speed in operation control.

(4) The purity of cutting gas is not enough, so it is necessary to provide high quality cutting working gas.

(5) The instability of the machine tool when it runs too long requires shutdown and restart.

2. Laser incomplete cutting

Reasons for incomplete laser cutting:

(1) The choice of laser nozzle does not match the thickness of the processing plate, so the nozzle or the processing plate should be replaced.

(2) The linear speed of laser cutting is too fast, so it needs operation and control to reduce the linear speed.

3. Abnormal sparks in cutting low carbon steel

When cutting low carbon steel normally, the spark beam is long, flat and less open. When abnormal sparks occur, the smoothness and quality of the cutting section of the workpiece will be affected.

When other parameters are normal, the following should be considered:

(1) The print head of laser head is seriously damaged, so the nozzle should be replaced in time.

(2) In the absence of new nozzle replacement, the cutting gas pressure should be increased.

(3) If the threads at the connection between the nozzle and the laser head are loose, the cutting should be stopped immediately at this time, and the connection status of the laser head should be checked, and the threads should be restored.

Laser cutting machine belongs to precious high-tech equipment, once there are various problems in operation, it will not only consume energy, but also increase costs, so it is best to choose the equipment of good quality when purchasing.
