Characteristics and development trend of laser cutting Application
laser cutting is a high power density energy produced by laser focusing. Under the control of the computer, through the pulse laser discharge and output controlled high repetition frequency pulse laser, the formation of a certain frequency, pulse width of the beam and the pulsed laser beam through optical transmission and reflection and through the focusing lens group focusing on the surface of the processing object, forming one tiny, high energy density spot, focal spot in the near surface processing, to I Nstantaneous high temperature melting or vaporization is material processing. Every high energy laser pulses instantly put object surface sputtering of a small hole, under computer control, laser processing head and the materials to be processed according to the pre painted graphics for continuous relative motion management. This will put the processing object into the desired shape. When cutting, a shares and beam coaxial flow by the cutting head ejects, melting or vaporization of material from the bottom of the incision blow out (Note: if blown gas and the material to be cut heat effect of reaction, the reaction will provide the additional energy required for cutting airflow and cooling have been; cutting surface, reduce heat affected zo NE and role to ensure that no contamination of the focusing mirror). Compared with the traditional plate processing method, laser cutting has high cutting (cutting width is narrow, small heat affected zone, incision smooth) quality, high cutting speed, high flexible (can be optional cut arbitrary shape), a wide range of material adaptability.
