The detail process of laser cutting machine commonly used mode

As the global low carbon, energy saving, environmental protection concept in the rise, the production of low carbon, energy saving, environmental protection, laser cutting machine has become the first choice of various industries. Common process model for the laser cutting machine are: melt cutting when the incident laser power density is more than a certain value, 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. Vaporization cutting 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. Oxidation melting cutting 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. Fracture cutting for easy to control heat damage of brittle materials, high speed, controlled by laser beam heating cutting, called control fracture cutting. The cutting process is the main content: laser beam heating brittle material is small area, causing the area of thermal gradient and severe mechanical deformation, cracks leads to the formation of a material. Laser beam may guide so long as you keep balanced heating gradient cracks in any direction.
