In the process of customizing sheet metals by Laser Cutting, sheet metals of different materials have different precautions.For stainless steel sheet metal, due to its high hardness, it requires a large power when cutting. At the same time, stainless steel is prone to produce scale at high temperatures, which affects the cutting quality. Therefore, to ensure the normal operation of the gas-assisted system of the Laser Cutting equipment, the use of appropriate auxiliary gases such as nitrogen can prevent oxidation and improve the finish of the cut surface. Moreover, the thermal conductivity of stainless steel is relatively low, and it is easy to produce heat concentration during the cutting process, which may cause deformation, so the cutting speed and power should be reasonably controlled, and multiple cutting methods can be used when necessary.For aluminum plates, which have a high reflectivity, special attention should be paid to safety during Laser Cutting to prevent equipment damage and personal injury caused by laser reflection. It is usually necessary to adjust the parameters of the laser, such as reducing the power and increasing the cutting speed. In addition, aluminum plates are soft and prone to burrs, and the pressure of the auxiliary gas can be appropriately increased to reduce the generation of burrs.For carbon steel sheet metal, although it is relatively easy to cut, it is also necessary to pay attention to controlling the cutting speed and power to avoid material deformation and hardness reduction due to overheating. At the same time, carbon steel will produce a lot of smoke and waste residue during the cutting process. Ventilation and dust removal measures should be taken to protect the health of operators and the normal operation of equipment.In short, in the process of Laser Cutting, sheet metal of different materials needs to reasonably adjust laser parameters according to its characteristics, select appropriate auxiliary gas, and take corresponding protective measures to ensure cutting quality and production safety. Only in this way can the advantages of Laser Cutting in the field of customized sheet metal be fully utilized to meet the needs of different customers.
