What are the precautions for fiber laser cutting machine cutting carbon steel?

When the fiber laser cutting machine is cutting carbon steel materials, due to the high hardness of carbon steel, in order to avoid problems, it is necessary to check and maintain the fiber optic equipment frequently. And if there is a problem during processing, it is necessary to investigate from all aspects of the fiber laser cutting machine. Under normal cutting conditions, the effect of cutting carbon steel should be burr-free and the traction line should be consistent. So what problems should the fiber laser cutting machine pay attention to when cutting carbon steel plates? Guohong Laser will answer for you.


1. Possible reasons include:
(1) When the laser focus position is shifted, do a focus position test and adjust according to the shift amount 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, and adjust it if it is not correct;
(3) The cutting line speed is too slow, and the line speed needs to be increased during operation control;
(4) The cutting gas purity is not enough, and high-quality cutting working gas needs to be provided;
(5) The instability of the machine tool running for too long requires shutdown and restart at this time.

2. The laser is not completely cut
Reasons for incomplete laser cutting:
(1) The choice of laser nozzle does not match the thickness of the processing board, and the nozzle or processing board needs to be replaced;
(2) The laser cutting line speed is too fast, and operation control is required to reduce the line speed.
(3) Abnormal sparks appear when cutting mild steel

When cutting low-carbon steel normally, the fire line is long, flat and less split. When abnormal sparks appear, the smoothness and processing quality of the cut section of the workpiece will be affected.
At this time, when other parameters are normal, the following conditions should be considered:
(1) The loss of the laser head nozzle is serious, and the nozzle should be replaced in time;
(2) In the absence of replacement of new nozzles, the cutting working gas pressure should be increased;
(3) If the thread at the connection between the nozzle and the laser head is loose, stop cutting immediately, check the connection status of the laser head, and reinstall the thread.

How many watts of fiber laser cutting machine can cut 10mm carbon steel?

Recommend 3000W or 4000W fiber laser cutting machine, if you cut the plates below 10mm, you can consider 3000W fiber laser cutting machine, the cutting speed and cutting accuracy of this wattage equipment can meet the requirements. If it is a large-scale cutting of metal sheets of about 10mm±2mm, then a 4000W fiber laser cutting machine should be considered.
