Nitrogen is generally used to cut stainless steel metal sheets to prevent oxidation, without burr edges, and can be welded directly without post-processing. According to the characteristics of stainless steel materials, the fluidity of the liquid can be accelerated, and the cutting efficiency can be higher and faster. However, the effect of cutting with oxygen may be worse than that of nitrogen, causing the end surface to be black and not smooth. laser cutting fume extraction system

Generally, oxygen will get better results when laser cutting carbon steel. While the oxygen reaction heat is used to increase the cutting efficiency in a large format, the generated oxide film will also increase the beam spectrum absorption factor of the reflective material. When using oxygen processing, there is a problem that the edges may be slightly oxidized. If users with strict requirements can use nitrogen for high-pressure cutting, of course, they can also paint the surface of the workpiece to achieve better cutting results. laser cutting fume extractor china

Aluminum is a highly reflective material among metal materials, which has high reflectivity and thermal conductivity. In recent years, the laser cutting machines of many manufacturers have installed "anti-reflection devices" to adapt to aluminum cutting. The use of laser cutting opportunities without "anti-reflection devices" has caused damage to their optical components. At the same time, depending on the power of the equipment, the thickness of the cut aluminum material is also different. Generally speaking, the thickness of stainless steel and carbon steel cut by the same equipment is thicker than that of high anti-reflection materials such as aluminum. Aluminum is also more suitable for cutting with nitrogen, and the cutting effect is good and the end surface is smoother. laser cutting fume filter
