Traditionally innovative

Half a century of Liebherr-Verzahntechnik GmbH means 50 years of commitment to the machinery and plant engineering industry. Gear technology originated in the technology of the revolving tower crane. Hans Liebherr wanted to buy a gear hobbing machine for gear manufacturing, but could not find what he wanted – so he simply built it himself. It’s a typical Liebherr story, since many sectors in the company group have emerged in this or in a similar way. Taking things into one’s own hands: an attitude that can still be found at Liebherr today.

Satisfied customers speak for themselves

E-cars are very demanding in terms of gear quality. Great Taiwan Gear relies on Liebherr machines.

From prototype to series production

It begins with an idea. But designers often have a long way to go before a perfect workpiece is made using a suitable manufacturing process. It is good that reliable partners such as Liebherr participate and share their experiences.

Top gear cutting tools, in-stock – with new material and coating

Simply order from the catalogue and two days later the new shaping tool will arrive: Liebherr makes the process as straightforward as this for customers and offers a broad range of stock tools available for immediate delivery. New: Instead of cutting material ASP2030 with a titanium nitride (TIN) coating, stock tools are now made as standard from ASP2052 with Alcrona Pro.

Breakthrough in automated machining of turbine blades

The aircraft propulsion systems of today are wonders of technology. Since air travel is rapidly growing in demand around the world, the production technology employed until now needs to be modernised.

ChamferCut: Chamfering despite interference contours

As before, ChamferCut is a technology with a great deal of development potential. A new upgrade is now pushing the limits of the impossible.
