Gas cutter for laser cutting machine using different material methods

With the development of laser cutting machine technology, the field of laser cutting is more and more extensive, and more and more materials are applicable. However, different materials have different characteristics, so the matters needing attention when using laser cutting are also different. The precautions when using laser cutting for different materials will be summarized in continuous practice.
Steel structure
This material will give better results when cut with oxygen. When oxygen is used as the processing gas, the cutting edges are slightly oxidized. For plates with a thickness of 4mm, nitrogen can be used for high-pressure cutting. In this case, the cutting edges are not oxidized. For plates with a thickness of more than 10mm, a special electrode plate can be used for the laser and the surface of the workpiece can be oiled during processing to obtain better results.
stainless steel
Cutting machine stainless steel needs: use oxygen, in the case where the edge oxidation does not matter: using nitrogen can get the edge without oxidation and burr, no need to do further processing. Coating the oil film on the surface of the board will get better results without reducing the processing quality.
aluminum
Despite its high reflectivity and thermal conductivity, aluminum materials up to 6mm thick can be cut, depending on the alloy type and laser capabilities. When oxidized, the cut surface is rough and hard. When using nitrogen, the cut surface is smooth. Pure aluminum is very difficult to cut because of its high purity. It can be cut only when a "reflective absorption" device is installed on the system. Otherwise reflections can damage optical components.
titanium
Titanium sheet is cut with argon and nitrogen as process gases
Copper and brass
Both materials have high reflectivity and very good thermal conductivity. Brass with a thickness of less than 1mm can be cut with nitrogen; copper with a thickness of less than 2mm can be cut, and the processing gas must be oxygen. Copper and brass can only be cut when a "reflective absorption" device is installed on the system. Otherwise reflections can damage optical components.
Synthetic material
Keep in mind the dangers of cutting and the hazardous materials that can be emitted when cutting synthetic materials. Synthetic materials that can be processed are: thermoplastics, thermosetting materials and elastomers.
Organic matter
There is a danger of fire in all organic cutting (use nitrogen as the process gas, and compressed air as the process gas). Wood, leather, cardboard, can be cut with a laser, the cutting edges will burn (brown).
