The application of laser cutting machines is becoming more and more widespread, and the applicable materials are also increasing. However, different materials have different characteristics, so the precautions to be taken when using a laser cutting machine are also different. Below is a brief analysis of the main materials used in laser cutting:
Structural steel:
This material will yield better results when cut with oxygen. When using oxygen as the processing gas, the cutting edge will undergo slight oxidation. For plates with a thickness of up to 4mm, nitrogen gas can be used as the processing gas for cutting.
stainless steel:
When cutting stainless steel, oxygen is required. If edge oxidation is not a concern, nitrogen can be used to obtain edges without oxidation or burrs, and no further treatment is needed.
aluminium
Despite its high reflectivity and thermal conductivity, aluminum materials with a thickness of less than 6mm can be cut, depending on the type of alloy and the capability of the laser.
titanium
Titanium plates are cut using argon and nitrogen as processing gases. synthetic material
organic compound
There is a risk of ignition in all organic cutting processes (using nitrogen as the processing gas or compressed air as the processing gas). Wood, leather, cardboard, and paper can be laser cut, but the cutting edges will burn
