The choice of different material gas laser cutting machine

Laser cutting machine in different structural steel material gas analysis, the material will get good results with oxygen cutting. When oxygen was used as processing of gas, cutting edge will be mild oxidation. About 4 mm in thickness plate, can use nitrogen as high pressure processing gas cutting. In this case, the cutting edge will not be oxidized. More than 10 mm in thickness of plate, the use of laser special plate and workpiece surface in the processing oil can get good effect. Stainless steel, cutting stainless steel need to use the oxygen, in the case of edge oxidation it doesn't matter, use nitrogen to get without oxidation without burr on the edge of a don't need to be dealt with. Oil film in the plate surface coating will get better effect of perforation, without reducing the processing quality. Aluminum, despite the high reflectivity and thermal conductivity, aluminum under 6 mm thickness can be cut, depending on the type of alloy and laser. When using oxygen cutting, cutting surface is rough and hard. With nitrogen, the cutting surface smooth. Because of its high purity pure aluminum is very difficult to cut, only 'reflection absorption devices are installed on your system when cutting aluminum. Otherwise would destroy reflection optical components. Titanium, titanium plate with argon and nitrogen as processing of gas cutting. Other parameters can refer to nickel chrome steel. Copper and brass, both material with high reflectivity and good thermal conductivity. The thickness of the laser cutting machine 1 mm below the brass may use nitrogen gas cutting; Thickness of 2 mm below the copper can be cut, processing must use oxygen gas. Only the reflection absorption devices are installed on your system when cutting of copper and brass. Otherwise would destroy reflection optical components.
