DuriAuxiliary gas for Fiber Laser Cutting, did you get the right one?
The schematic diagram of laser cutting is shown in the following.
During the process, auxiliary gas is necessary to blow off the slag/dross in the kerf and cool down the cutting surface, also it protects lens and nozzle of laser. Basically there are 3 kinds of gas: Oxygen, Nitrogen and Air, any of them affects directly to the cutting performance, speed, thickness etc. So we really need to think better before action.
Air
Air, as it's the most economic medium because it's much easier to obtain than oxygen and nitrogen, Every one knows the air contains about 20% oxygen and about 78% nitrogen, so it can make up for both shortage and cutting speed is slower than oxygen but faster than nitrogen. Since the oxygen is involved, the kerf turns a little bit yellow. It's the most economic option for you as long as you are okay with the color change.
Generally compressed air can be used for cutting sheet-metal parts, aluminum sheet, nonmetal and galvanized sheet etc., air assist can certainly reduce the oxide film and absolutely save your cost, therefore, air assist is more and more equipped in fiber laser cut industry.
Compressed air can be obtained easily with an air compressor, but not any air compressor can be equipped for Fiber Laser Cutter as the Air itself is not clean, especially after compressing, there are plenty of water, oil and particles and any of them sprayed on the lens, the transmission of laser beam will be seriously affected and focus scattered, resulting bad cutting effect such as bottom burrs or rough kerf, even obsolescence.
Situation could be much worse if it is high-power fiber laser, even a tiny particle or a little spray will very possibly burn your entire lens cone.
Dehaha 4-in-one (Compressor + receiver tank+ dryer + filters) high pressure air compressor is special compressor for Fiber Laser Cutting industry, custom built to provide filtered, dried, continuous reliable supply of high pressure compressed air at 2~10ºCdew point to assist laser cutting. Produce your own assist air at a fraction of the cost of cylinder.
