Turbine Part

    Initial situation

    The task is to produce different parts of an aircraft turbine in difficult to cut titanium. A big challenge in this material is to machine the precise bores. First priority in such expensive parts is process reliability.

    Material: Titanium

      Metric Imperial
    Bore-Ø: 44.442 +0.025 mm 1.7497 +0.001 in
    Length: 80 mm 3.1496 in


    Requirements

      Metric Imperial
    Surface: Ra 0.8 µm Ra 32 µin

     

     

     

     

    The URMA solution

    Standard RX medium reaming tool

    Modular reaming tool with integrated compensation mechanism

    The high precise ground carbide insert takes the responsibility for the final diameter.

    Highlights

    Final size responsibility is took by the reaming tool
    No wear compensation needed
    The surface is within measured and visual roughness specifications
    No scrap parts due to highest process reliability
