Integrated Laser System for Macroprocessing
    Integrated Laser System for Macroprocessing

    Macro-processing module equipped with an integrated multifunctional optical fiber laser beam made ​​by interconnecting several lasers and materials processing machines and computer-assisted correlation of their operation depending on the particular material and complexity of the piece.

     3D macro-processing operations of materials, surface treatments (hardening , alloying , cladding) - such as :

    • repair operations (reconstruction) worn regions (edges, sides etc.) of injection molds, casting molds etc. .
    • cutting and welding metal parts with a high degree of accuracy.
    • surface alloying treatments using the metal powders filler (WC, TiC ) or wired for  forging and injection molds, trees, etc.
    • welding and cutting operations of precision metallic materials of various thicknesses and types of melting or high thermal conductivity - as precision masks made by copper or alluminium.

      The system integrates the following lasers:
