Laser cutting parameter adjustment: laser cutting bending parts for different materials
Publish Time: 2024-05-13
Laser cutting technology is an indispensable part of modern manufacturing. Especially when dealing with laser cutting bending parts of different materials, the accuracy and efficiency of laser cutting are particularly critical. Therefore, it is crucial to adjust laser cutting parameters according to the characteristics of the material.
First of all, we need to understand that different materials respond differently to laser. For example, carbon steel has a high absorption rate of laser due to its high iron content, so the laser power and cutting speed can be appropriately increased during cutting. Stainless steel, because of its high hardness and high melting point, requires higher laser energy and slower cutting speed to ensure cutting quality.
Secondly, for materials such as aluminum plates and nickel alloys, due to their high reflectivity and viscosity, we need to pay special attention to the focus position of laser cutting and the selection of auxiliary gas. For aluminum plates, we can use high-purity nitrogen as auxiliary gas to reduce oxidation and burr generation. For nickel alloys, due to their high viscosity after melting, we may need to increase the oxygen flow to assist cutting.
When adjusting laser cutting parameters, we also need to consider the thickness of the material. Thicker materials require longer pulse widths and slower movement speeds to ensure the laser can fully penetrate the material and achieve high-quality cuts.
In short, for laser cutting bending parts made of different materials, we need to comprehensively consider the characteristics, thickness and cutting requirements of the material, and reasonably adjust parameters such as laser power, cutting speed, focus position, auxiliary gas, etc., to achieve efficient and accurate cutting. Only in this way can we give full play to the advantages of laser cutting technology and contribute to the development of the manufacturing industry.
