Different gas pressure fiber laser cutting machine

Different gas pressure fiber laser cutting machine.

Laser cutters use different auxiliary gases to cut different materials. The thickness of the cutting material is different, the pressure of the auxiliary gas is different from the required flow rate.And the pressure of the auxiliary gas has a direct influence on the result of the laser cutting.

Laser working gas is to generate laser light.The shielding gas is to protect the optical device and drive the shutter. Auxiliary gas can not only blow away the slag in time.But also cool the work piece and clean the lens. The use of different auxiliary gases can change the cutting speed and the surface quality of the kerf.Which is of great significance for the cutting of special metals.

Auxiliary gas types are oxygen, air, nitrogen and argon. Air nitrogen acts as a shielding gas during cutting to prevent oxidation of the film.argon is for titanium metal cutting.

1. Compressed air.

The air is suitable for the cutting of aluminum sheets, non-metal and galvanized steel sheets.Which can reduce the oxide film and save costs to some extent. Generally, the cutting plate is relatively thick, and the cutting end face is not too high. And in some sheet metal chassis cabinets and other product industries.

2. Nitrogen.

Nitrogen is an inert gas, which prevents oxidation of the cutting end face of the product during cutting and prevents combustion (it is easy to occur when the sheet is thick. It can be selected for products that require high cutting end faces and are not treated. For example, some decorative industries, aviation Special parts such as aerospace;

3. Oxygen.

Oxygen mainly acts as a combustion aid, which increases the speed during cutting and thickens the thickness of the cut. It is suitable for thick plate cutting, high speed cutting and very thin plate cutting. For example, some large carbon steel plates and some thick carbon steel structural parts can use oxygen.
