Principle Of Laser Cutting Machine
Laser cutting is to irradiate the workpiece with focused high power density laser beam to make the irradiated material melt, vaporize, ablate or reach the ignition point quickly. At the same time, the high-speed air flow coaxial with the beam is used to blow away the molten material, so as to realize the cutting of the workpiece.
Galvanized steel sheet is a kind of material commonly used 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 the shell of household appliances, civil chimneys, kitchenware, etc. is this material suitable for laser cutting machine?
Generally speaking, for galvanized steel sheet, laser cutting machine can easily cut, most organic and inorganic materials can be used, in the industrial manufacturing system commonly used in a variety of metal materials, no matter what kind of hardness, almost 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 cut 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 cut galvanized sheet section. Of course, the cutting cost also increases. The purity of nitrogen used for cutting should be higher than 99.5%. Improving the purity of nitrogen ensures that the cut does not change color in the process of cutting galvanized sheet.
