When cutting carbon steel materials with an optical fiber laser cutting machine, due to the high hardness of carbon steel, it is necessary to frequently inspect and maintain the optical fiber equipment in order to avoid problems. If there is a problem during processing, it is necessary to investigate 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 consistent. So what issues should be paid attention to when cutting carbon steel plates with an optical fiber laser cutting machine? Large image laser answers for you.

Precautions for cutting carbon steel with optical fiber laser cutting machine

Possible causes include:

(1) If the laser focus position shifts, perform a focus position test and adjust it according to the shift amount of the laser focus

(2) The output power of the laser is insufficient. It is necessary to check whether the laser generator operates normally. If so, observe whether the output value of the laser control button is correct. If not, adjust it

(3) The cutting line speed is too slow, and it is necessary to increase the line speed during operation control

(4) The purity of cutting gas is insufficient, and high-quality cutting working gas needs to be provided

(5) The machine tool runs for too long, causing instability. At this time, it needs to be shut down and restarted

2. Incomplete laser cutting

Reasons for incomplete laser cutting:

(1) The selection of the laser nozzle does not match the thickness of the processing plate, and it is necessary to replace the nozzle or the processing plate;

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

(3) Abnormal sparks when cutting low-carbon steel

During normal cutting of low-carbon steel, the spark beam length, flatness, and forking are relatively small, and abnormal sparks may affect the smoothness and processing quality of the cutting section of the workpiece.

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

(1) The laser head nozzle is severely damaged, and the nozzle should be replaced in a timely manner;

(2) In the absence of 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 becomes loose, immediately stop cutting, check the connection status of the laser head, and reinstall the thread.

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

A 3000W or 4000W fiber laser cutting machine is recommended. If the plates you cut are all below 10mm, a 3000W fiber laser cutting machine can be considered. The cutting speed and cutting accuracy of the equipment with this wattage can meet the requirements. If it is to cut metal plates of about 10mm ± 2mm in large batches, it is necessary to consider a 4000W fiber laser cutting machine.
