When the laser cutting machine is cutting carbon steel material, due to the 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 when processing, it is necessary to investigate from all aspects of the laser cutting machine. In the case of each cutting conditions are normal, the effect of cutting carbon steel should be burr-free and consistent traction line. So what are the problems that need to be paid attention to when the laser cutting machine is cutting carbon steel plate?
- Possible causes include:
(1) If the laser focus position 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 insufficient, and 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 if it is not correct, adjust it;
(3) The cutting line speed is too slow, and it is necessary to increase the line speed during operation and control;
(4) The purity of the cutting gas is not enough, and high-quality cutting working gas needs to be provided;
(5) The instability caused by the long operation time of the machine tool needs to be shut down and restarted at this time. - The laser is not completely cut.The reason why the laser is not completely cut:
(1) The selection of the laser nozzle does not match the thickness of the processing plate, and the nozzle or processing plate needs to be replaced;
(2) The laser cutting line speed is too fast, and it is necessary to control the operation to reduce the line speed.
(3) Abnormal sparks occur when cutting low-carbon steel
When cutting low-carbon steel normally, the fire bouquet is less long, flat and split. When abnormal sparks appear, it will affect the smoothness and processing quality of the cutting section of the workpiece.
At this time, under the condition that 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) In the absence of a new nozzle replacement, the gas pressure of the cutting work should be increased;
(3) If the thread at the junction of the nozzle and the laser head is loose, the cutting should be suspended immediately, the connection status of the laser head should be checked, and the thread should be reinstalled.
How many watts of fiber laser cutting machine can cut 10mm carbon steel?
3000W or 4000W fiber laser cutting machine is recommended. If the boards you cut are 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 you want to cut a large number of metal sheets of about 10mm±2mm, you should consider a 4000W fiber laser cutting machine.
