1.5kw fiber laser cutting machine uses high power density laser beam to illuminate the material,
so that the material is quickly heated to melt or vaporize the state,
as the beam of light on the material movement, the formation of a very narrow width of the cut or weld.
Laser processing has high efficiency, high energy density and softness, no matter from the accuracy, speed or efficiency, is the best choice for all walks of life.
In the process of laser being processed material absorption into heat energy, different power density, material surface caused by different changes,
with the temperature rise, the material will occur phase change, melting, vaporization and other state changes,
different states and changes have a great impact on the absorption of laser.
Many customers do plate gold processing in the purchase of fiber laser cutting machine,
will ask whether fiber laser cutting can cut aluminum, copper and other high anti-material. In fact, a few years ago,
fiber laser cutting machine can cut aluminum plate, in repeated attempts to innovate,
cutting high anti-material quality is also getting higher and higher.
Method 1: Judging by the laser output wavelength
For laser with different output wavelength; Different materials exhibit different absorption rates (high or not).
Method two: judging by the surface structure
The smoother the surface of the material, the lower the absorption rate of the laser.
If smooth enough (even stainless steel), it is also highly reflective for laser processing.
Method three: judge by resistivity
In general, the smaller the resistivity of the material, the lower the absorption rate of the laser (high reaction);
The higher the resistivity, the higher the absorption rate.
Method four: judge by the surface state
The absorption rate of the same laser varies with the temperature of the material surface (solid and liquid) (high reaction or not).
In general, the higher the temperature or surface is liquid, the higher the absorption rate of the laser.
Low temperature or solid is usually less absorbent than liquid.
