Machine concept

The new LC 180 / 280 machine platform allows for a modular design. This means many different technological applications or customer-specific requirements can be implemented. Liebherr gear hobbing machines are optimally customized to the requirements of universal usability. The high-performance gear hobbing machines are productive and manufacture in the highest quality with maximum availability.

  • Optimized base frame rigidity thanks to FEM simulation
  • Thermosymmetric machine design and integrated temperature compensation ensure consistent high quality
  • Fundamentally optimized chip removal system
  • High flexibility for various processes:
    • Gears, shafts, worm gears
    • Cluster gears
    • Skive hobbing/finish cutting
    • Position dependency
    • Milling of special profiles
  • Wet and dry machining
  • Hook-ready machine with a low space requirement, suitable for easy transfer
