Solution Of Slag of Cutting Material On Fiber Cutting Machine Fiber laser cutting machine is a large-scale, high-tech automatic equipment, now we analysis the over burned in the cutting carbon steel process. The burning edge is mainly occurred in cutting carbon steel material with oxygen as auxiliary gas. The key to solve the problem is how to restrain the generation of oxidation overheat. Here is our solution, for example, to assist oxygen in perforation, and to switch auxiliary air or using nitrogen for cutting. This method can be used to process the small holes of the 1/6 thick plate.The conditions are set to single pulse laser beam, high energy peak output and low frequency condition, which can effectively reduce the accumulation of molten metal on the material surface during perforation and effectively control the heat output.
