Laser cutting machines in the material analysis structure of different materials, the material will get better results when cutting with oxygen. When oxygen is used as the processing gas, the cutting edge is slightly oxidized. For plates up to 4 mm thick, high pressure cutting can be performed with nitrogen as the process gas. In this case, the cutting edge will not be oxidized. For plates with a thickness of 10 mm or more, special plates are used for the laser and oil is applied to the surface of the workpiece during processing to obtain better results.
Stainless steel (stainless acid-resistant steel), oxygen is required for cutting stainless steel. If the edge oxidation is not tight, nitrogen is used to obtain the edge of the oxidation-free and burr-free, and no further treatment is required. Coating the oil film on the surface of the board will result in better perforation without sacrificing processing quality.
Aluminum, despite its high reflectivity and thermal conductivity, can be cut to aluminum with a thickness of less than 6 mm, depending on the alloy type and laser capability. When cut with oxygen, the cutting surface is rough and hard. When nitrogen is used, the cutting surface is smooth. Pure aluminum is very difficult to cut because of its high purity, and aluminum can only be cut when a "reflective absorption" device is installed on the system. Otherwise the reflection will destroy the optical components.
Titanium and titanium sheets are separated by using argon gas and nitrogen gas as processing gases.
Copper and brass, both materials have high reflectivity and very good thermal conductivity. Brass with a laser cutting machine thickness of 1 mm or less can be cut with nitrogen; copper with a thickness of 2 mm or less can be cut, and oxygen must be used for the processing gas. Copper and brass can only be cut when a "reflective absorption" device is installed on the system. Otherwise the reflection will destroy the optical components.
