Principle Of Laser Cutting By Air

The principle of laser cutting by air is similar to that by nitrogen, which relies on the energy of laser to melt the metal and blow away the molten material by using high pressure. During this processing, some material will be oxidized or burned to form metal oxides on the cut surface.For example, gray solid Al2O3(alumina), black solid Fe3O4(ferrous oxide) and CuO(copper oxide).

The air itself exists in the atmosphere. Air compressor been used to compress the air into the air tank, and then the air be filtered, cooled and dried to remove water and oil then the air can be used. In theory, any metal material that can be melted by laser energy can be cut by air.

Cautions:

laser cutting by air, must ensure that the air been filtered by compressor, the air compressor and refrigerator should be maintained regularly.

If the air entering to cutting head contains water and oil, it will pollute the gas pipeline in a very short time and cause foggy of protective lens, thus affecting the cutting quality.In addition, if not change the protective lens in time, the internal temperature of the cutting head may rise under the irradiation of high power beam, which may cause damage to the internal mirror group.

In mass production, only take the cutting efficiency, cutting cost and cutting effect into consideration, can find the most suitable solutions with more cost-effective performance under the current cutting demand!
