    Gear shaping with the LS 400 EM - your advantages

    • Highest flexibility during production
      • Machining of external and internal gears
      • Shaping several gears with differing helix angles
      • Easy programming of helix angles up to 50°, including correction options
    • Saves time with uncomplicated setup process
    • Additional lead modifications (programmable)

    Shaping head

    With a maximum stroke length of 70 mm, this machine offers the ability to machine workpieces with a diameter up to 400 mm and a module of 5 mm. It is designed with a tangential-feed shaping head slide, making efficient production of a wide range of components possible with minimal setup. Thanks to flexible machining positions, multiple high-precision gears can be machined in a single clamping.

    The combination of an electronic helical guide with state-of-the-art electromechanical drive technology and a user-friendly CNC control system makes flank and helix angle corrections easy.

    Efficient and cost-saving shaping with wafer tools

    Liebherr’s innovative wafer tools are the perfect complement for shaping machines and enable significant reductions in production costs. Clamping thin wafer discs in a special frame and then installing them in the machine provides countless advantages:

    • No machine adjustment necessary after switching out the wafers within a workpiece lot
    • Economic series production
    • Optimal process reliability
    • Easy machine adjustments and reduced setup times
    • No machine adjustment necessary after switching out the wafers within a workpiece lot

    Maximum user-friendliness

    The optimized LHStation & LHMobile control panel

    With the control panel, Liebherr intelligently divides programming and machine operation between two of the system components: “LH Station,” the large, fixed monitoring unit for data input and process monitoring, and “LH Mobile,” the standardized, mobile handheld unit with context-sensitive user guidance during setup. Both devices are equipped with both a multi-touch interface and tactile elements for optimal operational speed and operational safety.
