Material analysis
With the development of laser cutting technology, laser cutting is used in more and more fields, and more and more materials are used. But different materials have different characteristics, so there are different points to be paid attention to when using laser cutting.
structural steel
When the material is cut with oxygen, good results will be obtained. When oxygen is used as the processing gas, the cutting edge will be slightly oxidized. For plates up to 4mm thick, nitrogen can be used as processing gas for high-pressure cutting. In this case, the cutting edge will not be oxidized. When the thickness of the plate is more than 10 mm, the special plate is used for the laser and the surface of the workpiece is oiled in the process, the better effect can be obtained.
stainless steel
Cutting stainless steel needs: oxygen is used, when the edge oxidation is not important; nitrogen is used to get the edge without oxidation and burr, so no further treatment is needed. Coating the oil film on the surface of the plate will get better perforation effect without reducing the processing quality.
aluminum
Despite its high reflectivity and thermal conductivity, aluminum with a thickness of less than 6mm can be cut, depending on the alloy type and laser capability. When cutting 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. Only when the "reflection absorption" device is installed on the system can the aluminum be cut. Otherwise the reflection will destroy the optical components.
titanium
Titanium plate is cut with argon and nitrogen as processing gas. Other parameters can refer to nickel chromium steel.
Copper and brass
Both materials have high reflectivity and excellent thermal conductivity. Brass with thickness less than 1mm can be cut with nitrogen; copper with thickness less than 2mm can be cut with oxygen. Copper and brass can only be cut when a "reflection absorption" device is installed on the system. Otherwise the reflection will destroy the optical components.
synthetic material
When cutting synthetic materials, keep in mind the danger of cutting and the possible discharge of hazardous substances. Processable synthetic materials include: thermoplastic, thermosetting materials and artificial rubber.
organic compound
There is a risk of ignition in all organic cutting (nitrogen can be used as processing gas, compressed air can also be used as processing gas). Wood, leather, cardboard and paper can be cut by laser, and the cutting edge will be burnt (brown).
