Gas quality in accordance with ISO 8573-1:2010; solid particles - grade 2, water - grade 4, oil - grade 3.
Nitrogen: Nitrogen with the minimum purity of 99.99% and the concentration ＜100ppm is used to cut stainless steel.
Oxygen: Oxygen with the minimum purity of 99.9% and the concentration ＜100ppm is used to cut carbon steel.
Compressed air: Compressed air should be clean, anhydrous, oil-free and have no impurities. It is used for thin carbon steel,
slim stainless steel, etc. if conditions permit. (The key parameters of air compressor should not be lower than the standards
following: Please choose screw air compressor as much as possible. The volume flow is related to the laser power. The
maximum working pressure is ≥1.6mpa, the pressure dew point is 2~8°C, the filtration precision is 0.01μm, and the oil
content of air outlet is ≤ 0.003ppm, Air cutting gas path input pressure ≤ 3Mpa; cooling gas input pressure 0-0.5Mpa).
Disclaimer: Any oxygen, nitrogen and compressed air used that are inferior to the above requirements will cause
irreversible pollution of pipelines, valves and cutting head of the machine tool; any losses and expenses caused
thereby shall be borne by customers, for which Bodor shall not be liable.
Lubricating oil: Please use liquid lubricating oil that meets the standard, and the No. 32 # lubricating oil is preferred.
