The laser cutting machine is a new type of product, which plays an important role in the operation of the factory and the production of products, and people with certain experience know that the laser cutting machine needs gas as an auxiliary operation when it is used. Some people will ask, then the laser Is oxygen safe for the auxiliary gas of the cutting machine?
When cutting steel or stainless steel and other materials, the laser cutting machine will use the auxiliary gas. For example, when oxygen is used as the auxiliary gas, it will produce an exothermic reaction, which is especially obvious when cutting carbon steel. This kind of scheme is widely recognized.
In this process, oxygen is used to project the laser beam on the metal surface to heat the steel plate and bring about an exothermic reaction. The temperature of the area reaches the melting point. The molten metal is blown out and separated from the material, forming a smooth surface. Cut surface with oxide layer, but on the other hand, when cutting stainless steel, because stainless steel has a higher melting point, its characteristics are also different. When cutting quality and smoothness are included in the assessment, because oxidation is used as auxiliary gas It will form residual oxides on the metal surface, so the cutting quality cannot reach good results.
In order to solve this problem, after repeated research by laser experts, nitrogen was finally used as the auxiliary gas. Because nitrogen is an endothermic process, essentially a process of evaporation and ablation, higher pressure means higher operating costs. Diameter has a greater impact on gas consumption, so cutting thicker materials requires larger nozzles, so laser cutting machines generally use nitrogen as an auxiliary gas.
The auxiliary gas of the laser cutting machine is best to use nitrogen, which is a better auxiliary gas confirmed by experts. Oxygen can be used as auxiliary gas and is safe, but it will cause the laser cutting machine's cutting effect to be poor and affect the product delivery Rate, it is easy to cause an increase in the product error return rate.
