Can fiber laser cutting machine cut galvanized sheet?

Fiber laser cutting machine has become the main means of processing metal in modern enterprises. Laser cutting is to use a focused high power density laser beam to irradiate the workpiece, so that the irradiated material can rapidly melt, vaporize, ablate or reach the ignition point. At the same time, the molten material can be blown away with the help of high-speed air flow coaxial with the beam, so as to cut the workpiece.

Galvanized steel sheet is a common material used in manufacturing. Galvanized steel sheet is coated with a layer of metal zinc to prevent corrosion on the surface of steel sheet and prolong its service life. It is mainly used in household appliance shells, civil chimneys, kitchen utensils, etc. Is this material suitable for laser cutting machines?

Generally, for galvanized sheet, Redssail optical fiber laser cutting machine can cut easily. All kinds of metal materials commonly used in industrial manufacturing system, such as copper, aluminum and aluminum alloy sheet, can be cut.

In the process of processing galvanized sheet, it is necessary to add auxiliary gas. The purity and pressure of auxiliary gas directly affect the quality of cutting sheet section. The purity of oxygen used for cutting should be more than 99.6%. The higher the purity of oxygen used for cutting, the higher the roughness and quality of cutting galvanized sheet section. Of course, the cutting cost will also increase. The purity of nitrogen shall be more than 99.5% during cutting. Improving the purity of nitrogen can ensure that the color of the cut seam will not change during the process of cutting galvanized sheet.
