Our expertise


NOVEXA carries out audits on a daily basis to determine the level of wear of equipment and work needs. Our audits focus on a list of 60 parameters that enable us to quantify equipment criticality level based on a simple, easy-to-interpret colour code.


  • Inspection Pignon/Couronne

    • Profile deformation, hardness
    • Surface defects and impacts
    • Vibrations and temperatures
  • Wear on rollers/tyres

    • Turning, tilting
    • Conicity, flatness, hardness
    • Surface defects and impacts
  • Alignment control/p>

    • Cold with Leica 5005 (3D analysis)
    • Hot with TT tools, shell test


NOVEXA revolutionizes industrial maintenance by offering on-site reprofiling of gears, as well as machining of treads and guide strips.
