The reason and solution of the failure of sheet and pipe integrated laser cutting machine

laser cutting (9)

Sheet and pipe integrated laser cutting machine is the laser from the laser, through the optical system, focused into a high power density laser beam, laser beam irradiation to the surface of the workpiece, so that the workpiece to reach the melting point or boiling point, at the same time with the beam of high-pressure gas coaxial melting or gasification of the metal blown away.

Here we come to understand the tube and plate integrated laser cutting machine common failure causes and solutions:

When processing carbon steel, burrs appear on the processed parts, the possible reasons include:
1.laser focus position offset, do focus position test, according to the laser focus offset amount to adjust;
2.laser output power is not enough, need to check whether the laser generator is working properly, if normal, then observe whether the output value of the laser control button is correct, if not then adjusted;
3.cutting line speed is too slow, need to increase the line speed in the operation control;
4.cutting gas purity is not enough, need to provide high-quality cutting gas;
5.machine running time is too long instability, this time you need to shut down and restart.

The laser did not cut all the reasons:
1.laser nozzle selection and processing plate thickness mismatch, replace the nozzle or processing plate;
2.laser pipe cutting processing line speed is too fast, need to operate the control to reduce line speed.
3.cutting mild steel when there is an abnormal spark normal cutting mild steel, spark beam long, flat, less open fork. The appearance of abnormal sparks will affect the smoothness of the cut section of the processed parts and processing quality. At this time in the case of other parameters are normal, the following should be considered:
(1) The laser head nozzle loss is serious, should be replaced in a timely manner nozzle;
(2) In the absence of a new nozzle replacement, the cutting gas pressure should be increased;
(3) If the nozzle and the laser head connection threads loose, then you should immediately pause the cutting, check the laser head connection status and re-apply the threads.
