Liebherr Used Machines – Gear Hobbing and Gear Shaping

Liebherr gear cutting machines are among the most precise and rigid machine tools in gear manufacturing – Liebherr covers several production processes, from continuous gear hobbing to gear shaping of demanding internal gears. Every machine we take into stock is technically inspected for control system, drive technology and mechanical condition. Our stock changes continuously; which Liebherr machines are currently available with full technical data is shown in detail below.

Frequently Asked Questions about Liebherr Used Machines

Not currently in stock. For gear grinding we recommend taking a look at our other manufacturers such as Reishauer, Kapp Niles or Gleason, along with a careful review of your technical requirements. Our Liebherr gear hobbing and gear shaping machines (LC 502 and LFS 380) run very precisely and are accurate enough for many applications. As a result, they are often a more cost-effective alternative to gear grinding.

In gear hobbing, a rotating hob cutter generates the toothing in a continuous generating process – ideal for external gears and high volumes. In gear shaping, a reciprocating cutting wheel generates the tooth profile and is particularly suited to internal gears, shaft shoulders and hard-to-reach contours.

Yes. The control system was extensively retrofitted in 2012 by a specialized control systems provider: a new Siemens Sinumerik 840D sl with Sinamics drive technology, an electronic gearbox for all generating and single-part processes, a climate-controlled cabinet, complete rewiring, and an absolute measuring system on the A-axis. This combines the solid mechanics of the original build year with an up-to-date control generation with long-term spare-parts availability. Visit our own modernization page for further projects such as boring mills, large milling machines and grinding machines.

No, this LFS 380 stands without a raiser block (e = 0). This is not a practical drawback for this machine: Liebherr gear shaping machines feature a generously sized Z-axis travel range that covers a wide range of workpiece heights even without a raiser block – a clear advantage over many competitor machines in series production.
