Process of laser cutting machine model:
a, vaporization cutting mode under the high power density of laser beam heating, the speed of the material surface temperature to the boiling point temperature fast, enough to avoid melting caused by heat conduction, so part of the material vaporized into steam, part of the material as the ejecta from the bottom of the kerf width auxiliary gas flow blown away.
2, melt cutting pattern
when the incident laser power density is more than a certain value, the material inside the beam spot on evaporated, formed holes. Once the holes to form, which will serve as a bold absorb all of the incident beam energy. Hole surrounded by a molten metal wall, then, and beam coaxial auxiliary air holes around the molten material. With workpiece moving, the hole by the synchronous transverse cutting direction to form a cut seam. To continue along the seam at the forefront of laser beam irradiation, continuous or pulse melting materials from being blown away from the seam.
3, oxidation melting cutting pattern
melt cutting generally use inert gases, if replaced with oxygen or other reactive gas, was lit materials under the irradiation of laser beam, and the chemical reaction of oxygen violent and produce another source of heat, called oxidation melting cutting.
