How to get a good cutting effect of Fiber laser cutter?

Laser-cut carbon steel, sometimes burrs on the edge of the workpiece, making the surface appear not smooth, and some are difficult to remove, mainly cause by the following:

Firstly,The upper and lower positions of the laser focus are not correct. It is necessary to do the focus position test and adjust according to the offset of the focus.
Secondly,The nozzle selection is not suitable, replace the nozzles.
Thirdly,The purity and pressure of the cutting gas are insufficient, and it is necessary to provide high-quality cutting working gas and increase the pressure.
Fourthly,If cut quadrilateral, the adjacent two sides will have burrs, indicating that the center of the optical path is offset, and readjust the center point of the optical path from the nozzle; if there are burrs on the two parallel sides, There is a problem with the verticality of the machine.
The verticality of the laser head can taught according to the direction of the burr of the parallel side. Please check whether the roundness of the nozzle of the nozzle has changed. It must be ensured that the roundness of the nozzle is a full circle. .
There are many reasons why can not cut off the sheet plate. The most common ones are as follows:
Firstly, The power of the laser is reduce or the lamp is aging, so that the energy of the laser beam is not enough, and the template is not cut. Need to adjust the laser power to replace the laser generator lamp.
Secondly,the cutting speed is too fast, according to the thickness of the cutting plate to select a suitable cutting speed.
Thirdly,Check whether the output pressure of the proportional valve is consistent with the cutting pressure set by the upper computer, and whether the oxygen meter is at the indication of 10 kg.
Then,Check whether the protective lens is damage or not, and replace the protective lens.
Next,The focus position is not suitable, and the focus position is adjust according to the type of sheet thickness.
Finally,Under the premise of protecting the lens and cutting speed and air pressure, check whether there is any problem with the fiber interface. If there is no problem with the fiber interface, please check whether the collimating lens and the focusing lens of the laser cutting head are damage. If there is damage. Please replace it in time.
Hope it is helpful to you.
