High Precision Laser Cutting Service - Metal & Brittle Materials , Advanced Vaporization, Melting & Oxidation Techniques For Optimal Kerf Control

1, Vaporization.
In the high power density laser beam heating, the surface temperature rose to boiling point temperature of the speed is so fast enough to avoid melting caused by heat conduction, so part of the material vaporized into steam disappeared, some material as ejecta from the kerf bottom is auxiliary gas flow blown away.

2, Melting cutting.
When the incident laser beam power density exceeds a certain value, the beam irradiation point inside the material began to evaporate, forming holes. Once the hole formed, it will be as bold to absorb all the incident beam energy. Holes surrounded by molten material, and then, with the beam axis of the auxiliary air holes around the molten material away. With the workpiece movement, the direction of synchronous sliding hole formed by cutting a kerf. Laser beams to the front along the slit exposure, continuous or pulse of melt material from being blown away within the seam.

3, Oxide melt cutting.
General use of inert gas melt cutting, if replaced by oxygen or other reactive gases and materials in the laser beam irradiation was lit, and oxygen to the intense heat of chemical reaction, the other is called oxidation melting cutting.

4, Control, fault cutting.
For brittle materials, easy to heat, heated by a laser beam at high speed, controllable cut off, called the control fault cutting. Main contents of this cutting process: Laser beam heating small areas of brittle materials.
