Laser

Laser beam machining (also indicated with the acronym LBM) is a thermal process that uses a laser beam as a heat source, since it can be easily concentrated with lenses reaching a power density of more than 1 MW/mm2. At the moment in which the laser interacts with the material, the energy of the photons is absorbed by the material being processed, locally causing a rapid rise of temperature, leading to melting or boiling, removing the material without mechanical contact in the expulsion of the molten material, vaporization or ablation mechanisms. Unlike conventional processes you do not have to use and the removal of the material does not depend on its hardness, but on the optical properties of the laser and the optical and thermophysical properties of the material. For this reason, it is particularly suitable for working at high temperature resistant alloys, carbides, fiber-reinforced composites, ceramics and stellite.
