Can laser cutting machine cut galvanized sheet 

Laser cutting machine processing metal has become the main method of modern processing enterprises. Laser cutting uses a focused high-power density laser beam to irradiate the workpiece to quickly melt, vaporize, ablate or reach the ignition point of the irradiated material. At the same time, it is coaxial with the beam The high-speed airflow blows away the molten material, so as to cut the workpiece.

Galvanized sheet is a relatively common material used in manufacturing. Galvanized steel sheet is to prevent corrosion on the surface of the steel sheet and extend its service life. The surface of the steel sheet is coated with a layer of metallic zinc. Mainly used in household appliances shells, civil chimneys, kitchen appliances, etc., is this material suitable for laser cutting machines?

Generally for galvanized sheets, laser cutting machines can cut easily, most organic and inorganic materials can be used, and various metal materials commonly used in industrial manufacturing systems, regardless of their hardness, are almost cut. Copper, aluminum and their alloy plates are no problem.

In the process of processing galvanized sheet, auxiliary gas needs to be added. The purity and pressure of auxiliary gas directly affect the quality of the cut sheet section. The oxygen purity for cutting should be above 99.6%. When the oxygen purity for cutting is higher, the section of galvanized sheet is cut. The higher the roughness and quality, of course the cutting cost will also increase. The nitrogen purity during cutting should be above 99.5%. Increasing the nitrogen purity can ensure that the seam does not change the color during the cutting of the galvanized sheet.
