。 Laser cutting machine for heat damage of brittle materials easily, high speed, controlled by laser beam heating block, called control fracture cutting.

oxidation melting cutting laser cutting machine.
control fracture cutting laser cutting machine. Laser beam may guide so long as you keep balanced heating gradient cracks in any direction. Once the holes to form, which will serve as a bold absorb all of the incident beam energy. Inherited along the seam at the forefront of laser beam irradiation, continuous or pulse melting materials from being blown away from the seam. Under the high power density of laser beam heating, the material surface temperature to the boiling point temperature speed is so fast, enough to avoid melting caused by heat conduction, and department of materials evaporation disappear into steam, department of materials as the ejecta from the bottom of the kerf width auxiliary gas flow blown away. 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, leads to the formation of a material. Holes is encircled by the molten metal wall, then, with the beam coaxial auxiliary air take hole near the molten material.
vaporization cutting. Melt cutting generally use inert gas, 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.
fusion cutting laser cutting machine. Follow the movement artifacts, holes by synchronous transverse cutting direction to form a cut seam. When the incident laser power density is more than a certain value, the beam internal open steamed originating point material, the formation of the hole.
