Laser cutting is to use the focused high-power density laser beam to irradiate the workpiece, so that the irradiated material can quickly melt, vaporize, ablate or reach the ignition point. At the same time, with the help of the high-speed air flow coaxial with the beam, the molten material can be blown away, so as to cut the workpiece.
Galvanized steel sheet is a commonly used material in manufacturing industry. Galvanized steel sheet is coated with metal zinc to prevent corrosion on the surface of steel sheet and prolong its service life. It is mainly used for household appliance shell, civil chimney, kitchenware, etc. is this material suitable for cutting with laser cutting machine?
Generally speaking, for galvanized steel plate, laser cutting machine can easily cut, and most organic and inorganic materials can be used. All kinds of metal materials commonly used in industrial manufacturing system can be cut almost no matter what hardness it has.
In the process of processing galvanized sheet, auxiliary gas needs to be added. The purity and pressure of auxiliary gas affect the quality of cutting sheet section. The purity of oxygen used for cutting shall be more than 99.6%. When the purity of oxygen used for cutting is higher, the roughness and quality of cutting galvanized sheet section are higher. Of course, the cutting cost is also increased, and the purity of nitrogen during cutting shall be higher than 99.5%. Improving the purity of nitrogen ensures that the cut will not change color during the cutting of galvanized sheet.
