Auxiliary blowing parameters in the process of laser cutting machine

Auxiliary blowing parameters in the process of laser cutting machine in the process of laser cutting, especially for easy oxidation of steel, titanium metal cutting, using the auxiliary oxygen blowing method, can produce oxidation exothermic reaction, can blow plasma cloud block of laser beam, can be blown off in the molten metal cutting slot. The role of the total effect and increase the role of the incident laser power is considerable. So, auxiliary air blow is to improve the cutting speed, important factors to ensure the quality of cut surface. Because the exothermic oxidation process, give up quantity of heat is related to gas flow, cut the slot between the injection of molten metal and the auxiliary related to the size of the gas pressure on the center of fine line. So in the process of laser cutting machine cutting, to research the kinds of auxiliary gas, flow rate and pressure on the influence of cutting speed.
