Generally speaking, Common laser cutting machine are used in laser cutting process. Its process
have different requirements, for example, the process of laser cutting machine, there are a variety of different requirements.
1. Control fracture cutting; Easy to heat damage to the brittle material, heated by the laser beam at high speed, a controllable cut, called control faults cut.
This laser cutting process main contents are: laser beam heating the brittle material small area,causing the thermal gradient region is large and severe mechanical deformation, and cause the material to crack formation.
Maintain a balanced heating gradient, the laser beam can be guided to the crack is generated in any desired direction.
2. Oxidation melting cutting;
The melted cutting Usually inert gas is used, if replaced by oxygen or other reactive gas, material under the irradiation of the laser
beam is ignited, a violent chemical reaction with oxygen and produce another heat source, called oxidative melting cutting.
3. Melting Cutting;
When the incident laser beam power density exceeds a certain value, the beam irradiation point at which the material internal open
mother evaporation, the formation of holes. Once this orifice is formed, which serves as the blackbody absorb all of the incident light beam
energy. The orifice is surrounded by, and then molten metal wall, coaxially with the beam of secondary airflow around the holes of the molten
material away. As the workpiece is moved, the holes traversed simultaneously cutting direction to form a slit. The laser beam continues along
the leading edge of this seam irradiation, molten material within the seam continuous or pulsating from being blown away.
4. Vaporesection cutting ;
Under heating of the high power density of the laser beam, the surface temperature rose to the boiling temperature of the speed is so fast
enough to avoid heat conduction caused by the melting, so that the portion of the material is vaporized into steam disappears, the portion of the
material from the bottom of the slit as the ejecta The secondary gas stream blown away.
