Auxiliary gas of laser cutting machine
When cut different metal materials, laser cutter needs different auxiliary gas. And for different thickness of metals, it needs different air pressure and gas flow. That means to choose right assist gas and gas pressure are directly effect result of laser cutting.So today we want to introduce the auxiliary gas of laser cutting machine for you.
The auxiliary gas can not only blow away the slag on metal material in time, but also cool the it and clean the lens.
The main types of assist gases that XTLASER using are oxygen, air and nitrogen.
- 1. compressed air
Air is suitable for cutting aluminum, non-metallic and galvanized steel plates. To some extent, it can reduce oxide film and save cost. It is generally used when cutting plate is not thick, and the requirement for cutting end face is not too high. You can use it to cut some products such as sheet metal case, cabinet, and so on.
Nitrogen can cut aluminum and stainless steel.Not suitable for carbon steel.Carbon steel need Oxygen.It will let the cutting edge looks better and ligher.
- 3. oxygen
Oxygen mainly plays a role of combustion support, it can increase the speed of cutting and the thickness of cutting. Oxygen is suitable for thick metal cutting, high speed cutting and extremely thin metal cutting. For example, such as some thicker carbon steel plates, oxygen can be used. When cutting metals of different materials and thickness, choosing the suitable gas can help to shorten the cutting time and improve the cutting effect.
