What is the application of laser cutting machine auxiliary gas?
Author: Date: 2019-11-03 Hits: 76 two-dimensional code sharing

When performing laser cutting, auxiliary gas is essential. There are usually three types of auxiliary gas for laser cutting machine : air, nitrogen and oxygen. Different auxiliary gases are used for cutting different materials:

1.Compressed air

Air is suitable for cutting aluminum, non-metal and galvanized steel. To a certain extent, it can reduce the oxide film and save costs. Generally used when the sheet is relatively thin and does not require high cutting surface. In some industries such as sheet metal cabinets and cabinets, compressed air is more commonly used. ?

2.Nitrogen

Nitrogen is an inert gas, which prevents oxidation of the cutting end surface of the product when cutting, and prevents combustion (prone to occur when the sheet is thick). Nitrogen can be selected for products that require high cutting end surfaces and do not need to be exposed, such as some decoration industries, aerospace special parts and so on.

3.Oxygen?

Oxygen mainly plays a role in supporting combustion, which can make the cutting speed faster and the thickness that can be cut thicker. Oxygen is suitable for thick plate cutting, high speed cutting and very thin plate cutting. In some large carbon steel plate and thick carbon steel plate structure cutting, oxygen is often used.

The auxiliary gas can not only blow away the slag in time when the laser cutting machine is running, but also can cool the workpiece and clean the lens. In operation, we should choose the appropriate auxiliary gas according to the cutting material and thickness.
