How to make the cutting quality of the laser cutting machine better

Laser cutting machine as a high-precision processing equipment in modern manufacturing industry, its cutting quality is directly related to the accuracy and beauty of the product. However, in the actual use process, we sometimes encounter poor cutting quality. In the face of this problem, we should actively find out the reason and take corresponding measures.
When the cutting quality of the laser cutting machine is poor, further inspection should be carried out, and the inspection content and order are as follows:
1. Cutting height: It is recommended that the actual cutting height be controlled between 0.8mm-1.2mm, if the actual cutting height is not good, it needs to be calibrated;
2. Nozzle: Check whether the nozzle type and size are wrong, if it is correct, you need to check whether the nozzle is damaged and whether the roundness is normal;
3. Optical center: It is recommended to use a nozzle with a diameter of 1.0mm for optical center inspection, and the optical center focus is between -1 and 1, so that the light spot is small and easy to observe;
4. Protective lens: Check whether the protective lens is clean, requiring no water, no oil and no slag point, cold weather or low temperature of auxiliary gas will also protect the lens fog;
5. Focus: Check whether the focus is set correctly;
6. Cutting parameters: If the above five checks are no problem, you need to modify the parameters;

Cutting carbon steel section problem:

Thin plate section is not bright enough, thick plate section is rough.
In order to bright section, first of all, the plate is good, the surface is no rust, no paint, no oxidation, and then ensure that the oxygen purity is above 99.5%, the small nozzle is double-layer 1.0 or 1.2 when cutting, the cutting speed is above 2m/min, and the cutting pressure should not be too large; Cutting thick plate section quality is good, first of all, plate and gas purity, secondly, the selection of nozzles, the larger the aperture, the better the section quality.

Cutting stainless steel hanging slag: If the corner hanging slag can first consider the corner rounding, the parameters can reduce the focus, increase the air pressure, etc.; If the whole slag is hung, it is necessary to reduce the focus, increase the air pressure, and increase the nozzle; If the granular soft slag is hung as a whole, the cutting speed can be appropriately increased or the cutting power can be reduced; If the side near the end of the cutting is hanging slag, you can check whether the gas flow is low.
