All metals reflect CO2 laser beams until a certain power density threshold is reached. Aluminum is more reflective than C-Mn steel or stainless steel and has the potential to cause damage to the laser itself. Most laser cutters use a laser beam aligned perpendicular to the flat sheet of material.
If the laser beam is reflected off the slab, it can travel back through the beam delivery optics and into the laser itself, potentially causing significant damage. This reflection is not entirely from the sheet surface, but is caused by the formation of a highly reflective molten pool. For this reason, simply spraying the surface of the sheet with a non-reflective coating will not completely eliminate the problem.
With good, consistent cutting parameters, the possibility of reflections can be reduced to almost zero, depending on the material used. However, there is still a need to be able to prevent damage to the laser in the event of problems with development conditions or equipment. The "aluminum cutting system" used by most modern equipment is actually a way of protecting the laser, not an innovative cutting technique.
The fiber laser cutting machine uses a fiber laser generator as the light source. The laser beam energy density is high, and the light source is stable and reliable. It can be used for both plane cutting and three-dimensional cutting. The cutting speed is fast and the edges are neat and smooth. middle. Bestway Laser's aluminum laser cutters fire a latent laser beam to melt the metal. It then helps to blow out the molten material for cutting.
Cutting reflective metals like copper and brass makes fiber laser cutters significantly better at this than CO2 laser cutters.
