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.
Th auxiliary gas can not only blow away the slag on metal material in time, but also cool the it and clean the lens.
Here are mainly auxiliary gas of fiber laser cutting machine,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. It is used in some products such as sheet metal case, cabinet, and so on.
- 1. nitrogen
Air is suitable for Stainless steel,it can keep cutting edge bright.and if use O2 for nitrogen,Edge yellowing,so if cut stainless steel ,N2 is best choose for customer.
- 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.
Here are Auxiliary gas function:
- Blow away the residue to achieve the best cutting results.
- Protective lens,avoid slag sticking on the lens to affect cutting quality.
- It can make the cutting surface smooth，no burr, no scraping.
- It can react with materials to increase cutting speed,for example,Use of oxygen to help burn.
