The auxiliary cutting gases in fiber laser cutting machines serve multiple purposes:
1.Protective Function: Auxiliary gases protect the optical components of the fiber laser cutting machine. By blowing gas, they prevent metal debris or molten material from adhering to lenses and optical systems, maintaining equipment cleanliness and preventing damage.
2.Cutting Assistance: Some gases (such as nitrogen, oxygen) assist in the cutting process. Oxygen reacts chemically with the cutting area, providing higher cutting speeds and cleaner cuts. Nitrogen is commonly used for cutting metals like titanium alloys and stainless steel, reducing oxidation and achieving better cutting quality.
3.Cooling Effect: Auxiliary gases help in cooling the workpiece during cutting, controlling the heat-affected zone and improving cutting quality.
4.Waste Removal: Gases assist in removing molten metal or waste generated in the cutting area, ensuring a clean cut.
The selection of these auxiliary gases depends on the material used and the type of cutting required. Proper selection and control of these gases optimize the cutting process, enhancing production efficiency and cutting quality.
