Gear shaping machine

The fully electronic shaping head

The new LS 180 E gear shaping machine with an electronic shaping head stands out on account of its enormous flexibility. It can machine spur and helical gears in one clamping and is thus capable of shaping several gears on one workpiece.

Highlights

  • Time-consuming change of mechanical helical guides and the arising extensive procurement are completely eliminated
  • Set-up process for a workpiece change is reduced to a minimum
  • Gear shaping of several teeth with different helix angles possible in one clamping

Generating and profile grinding machine

Topological CBN generating and profile grinding as economical alternative

The non-dressable grinding tools of the generating and profile grinding machines LGG 180/280 combine high tool quality, simple handling, as well as a very long service life.

Highlights

  • Machine
    • High component quality & very high SPC (1-table concept)
    • Fast set-up and short idle times
    • Technological flexibility for internal and external teeth
  • CBN benefits
    • Non-dressable tool
    • Easy operation similar to gear hobbing
    • Significantly reduced measuring and inspection efforts
  • Integrated centrifuge
    • Clean, drip-free workpieces, no oil carryover
    • Minimum set-up work
    • SPC/NOK removal at the centrifuging station
    • Closed loop solution between WGT 280 measuring machine and LGG 280 generating and profile grinding machines

New at Liebherr: measuring technology

The WGT series

The four-axle measuring devices in the WGT range have high-precision mechanics and electronics, which are controlled by intelligent and user-friendly software.

Highlights

  • Lasting precision with lapped granite guides with consistent thermal behavior, paired with air bearings.
  • Low operating costs thanks to contactless guides and reliable probes, as well as affordable spare parts.
  • Flexible for all types of teeth and other tasks can be configured
  • User-friendly user interface and ergonomic design
  • Gear cutting machines and measuring systems as closed loop system solutions from a single source
