The working principle of laser cutting machine is based on what procedures

The working principle of laser cutting machine is the first, according to what procedures of the laser energy in the form of light is concentrated into a high density of beam, the beam to the work surface, produce enough heat, melt materials, coupled with high pressure gas with beam coaxial direct removal of molten metal, so as to achieve the purpose of cutting, it shows that laser cutting processing has essential difference with the mechanical processing machine tool. Second, the use of the laser beam is emitted from the laser generator, the light path system, focusing on a condition of high power density beam of laser cutting machine, laser heat absorbed by the workpiece material, workpiece temperature rise sharply, arriving at boiling point, the material began to boil and forming holes, accompanied by high pressure air flow, with the movement of the relative position between the beam and workpiece, eventually make the material become cut seam. When the process parameters (kerf width Cutting speed and laser power, gas pressure, etc. ) And trajectories are controlled by CNC system, cutting seam and slag is a certain pressure of auxiliary gas blowdown. Cutting speed and laser power, gas pressure.
