When the fiber laser cutting machine cuts 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 check 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 pulling line should be consistent. So what problems should fiber laser cutting machines pay attention to when cutting carbon steel plates? Datu Laser will answer for you.

Precautions for cutting carbon steel with fiber laser cutting machine

1. Possible reasons include:

(1) The focus position of the laser is shifted, do 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 control

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

(5) The instability of the machine tool due to long running time, at this time, it needs to be shut down and restarted

2. The laser is not completely cut

Reasons for incomplete laser cutting:

(1) The selection of the laser nozzle does not match the thickness of the processed plate, and the nozzle or the processed plate 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 low carbon steel

When cutting low-carbon steel normally, the spark bundle is long, flat and less split. When abnormal sparks appear, it will affect the smoothness and processing quality of the cut section of the workpiece.

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

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

(2) In the case of no replacement of new nozzles, 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, stop cutting immediately, check the connection status of the laser head, and re-install the thread.

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

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