How to deal with the slag on the cutting board of the laser cutting machine?

Most laser cutting customers should have encountered similar problems, there is slag on the cutting board, what is going on? What should I do? Let’s take a look at the causes and corresponding solutions of professional laser cutting machine manufacturers for the dross generation.

Improper setting of cutting parameters: such as too low laser power, too fast or too slow cutting speed, insufficient auxiliary gas pressure, etc., which will lead to incomplete cutting or excessive melting, resulting in dross. Therefore, the appropriate parameter combination should be selected according to the characteristics of the material to be cut.

Beam focus point offset: The position of the beam focus point before or after will affect the cutting quality, and it is easy to produce dross. It is necessary to check the optical path and lens regularly to ensure that the beam is accurately focused.

The characteristics of the material to be cut: such as thick plate, small hole processing, stainless steel, aluminum alloy and other materials are more likely to produce dross, and need to adjust parameters or take special measures. For example, increase the power and air pressure, slow down the cutting speed, etc.

Selection and quality of auxiliary gas: Although O2 gas can increase the cutting speed, it is more likely to produce dross, especially in stainless steel cutting. High-purity N2 or air should be selected as the auxiliary gas, and check that there is no leakage in the gas pipeline.

If you feel that the situation of dross is similar to what I described above, you can deal with it according to the solution we gave. Generally, if you want to cut with high precision and good quality, you need to test the machine and try cutting before the official operation of the equipment to ensure the best cutting process parameters. In addition, the operator should carefully observe the spark condition and the airflow effect when cutting, and adjust the relevant parameters in time, which will also help to solve and prevent the problem of slag on the board. If the above methods of dealing with slag cannot solve your problem of slag hanging, please call us for consultation. We will provide technical support related to the cutting quality of various precision laser cutting machines at any time!
