The cutting of the three major common problems in production process of carbon steel

Cut, as the name implies, is to use the focus of high power density beam artifacts, cause the irradiation materials rapidly melting, evaporation and ablation or reach the ignition point, at the same time with the aid of high-speed airflow and beam coaxial blow molten material, so as to realize the workpiece cut open.

in the sheet metal industry, cutting is widely used in steel industry. Today ZuoLong machinery to introduce the under cut in carbon steel and common problems in the process of adjustment method.

a, cutting carbon steel, machined part a burr

general mechanical parts appear burr, the possible reasons include:

( 1) Focal shift, focus location tests, adjustments according to the offset of focus;

( 2) The output power is not enough, need to check whether the generator working normally, if the normal, is to observe the control button on the output value is correct, if not try to adjust the right;

( 3) Cutting speed is too slow, need to increase the linear velocity when operating control;

( 4) Cutting gas purity is not enough, need to provide the high quality of cutting gas;

( 5) Machine tool operation instability time is too long, need to shutdown restart at this time.

2, the reasons for not completely cutting:

( 1) Nozzle selection and processing of the thickness of the plate do not match, replace the nozzle or processing plate;

( 2) Reduce the linear velocity of the cutting speed is too fast, need operating controls.

3, cutting carbon steel when appear abnormal spark

normal cutting carbon steel, fire flower long, flat, open fork is less. Appear abnormal spark will affect the smoothness of the cutting section of machined part and machining quality.

in the case of other parameters is normal at this time, should consider the following:

( 1) Head nozzle loss serious, should be timely replacement of the nozzle;

( 2) In the absence of new nozzle replacement, should step up cutting working gas pressure;

( 3) If the nozzle head joint thread and loose, should immediately stop cutting, check the connection status, again for thread.
