What is the root cause of burrs when laser cutting machines process sheet metal?

In the process of laser cutting sheet metal, the quality of the workpiece obtained is not satisfactory, and there are a lot of burrs. Therefore, many customers began to have doubts about the product quality of laser cutting machines, but the actual situation is not the case. Because the burrs generated by laser cutting sheet metal are not a single physical phenomenon, but are caused by the combined action of multiple factors. Regarding the causes of burrs when laser cutting sheet metal, we will make a concise analysis for you.

In the process of workpiece processing by the cutting machine, due to the high-energy irradiation of the laser beam on the surface of the workpiece, the surface of the workpiece will quickly vaporize and evaporate, thereby achieving the effect of laser cutting processing. In order to achieve this goal, it is first necessary to provide a suitable auxiliary gas to reduce the high temperature and ablation of the laser beam on the surface of the workpiece, thereby improving the cutting quality and efficiency. However, there is a crucial device here, that is, the auxiliary gas, which we must pay enough attention to.

In laser cutting, auxiliary gas is essential to prevent slag from adhering to the cut material. The function of the auxiliary gas is to blow away the slag on the surface of the workpiece after the irradiated surface of the workpiece is vaporized. If this auxiliary gas is not used, the slag will form burrs on the cutting surface after cooling. So we must consider whether the auxiliary gas can successfully blow away the slag and generate burrs. This is the core factor that produces burrs. Therefore, auxiliary gas is a very important link. Equipment quality issues and parameter settings are also one of the influencing factors. Therefore, after the customer purchases a laser cutting machine, it is necessary to have an experienced operator to accurately debug the equipment. Solutions to the burr problem:

1. An air compressor must be equipped during the cutting process and auxiliary gas must be used;

2. Please find an experienced operator to adjust the parameters of the laser cutting machine until everything returns to normal.
