If you need high-quality gear cutting tools at short notice, you can request them online from Liebherr. Many customers already use the practical and uncomplicated online catalog on the Liebherr-Verzahntechnik GmbH website. Haider Arroum, Team Leader for Tool Sales in Ettlingen, explains how it works.

Liebherr in the United States is proud to celebrate five decades in North America and establish itself as a leading manufacturer. Liebherr has built its U.S. business on a foundation of trust, innovation and engagement with customers. Five decades later, Liebherr’s growth, diversity and stability are evidence of how the company is united by success with customers as they work on the challenges of tomorrow and focus on the future together.

Liebherr presents the new series of generating and profile grinding machines for hard machining of external and internal gears on workpieces with diameters of up to 500 millimeters. The LGG series follows the successful Liebherr LCS 300 to 500 series. With an impressive range of added features, they offer more flexibility and grinding performance with a significantly reduced footprint.

Liebherr-Verzahntechnik GmbH presented four machine concepts at EMO 2019. These were characterized above all by their versatility. With technologies such as shaping, worm milling, grinding and skiving, the exhibited products offered a wide range of options for every requirement in gear technology. Here is a review of the trends at the leading trade fair for metal machining.

Gear skiving is over 100 years old and has recently been experiencing a renaissance as a flexible and economical alternative to other gear cutting methods. However, this complex process frequently presents great challenges to users. In addition to Skiving3, a “complete package” consisting of machine, tool and technology, Liebherr now also offers skiving tools for suppliers and contract gear manufacturers – and the appropriate consultation, if desired.

Clamping units for gears with short delivery times at low costs – due to the high level of individualization of clamping devices, these demands were often diffi cult to reconcile. That’s now a thing of the past. The segment clamping arbor SECLA from Liebherr is an innovative, inexpensive standard solution with short delivery times for a maximum application range in gear manufacturing machining.

Insights into the highlights of the group

The machining of gears with interfering contours for the aerospace industry places the highest demands on the grinding tool and often cannot be carried out with standard grinding heads due to the small tool diameters. Liebherr has developed an auxiliary spindle for these applications which can be retrofitted. This enables the production of challenging aerospace components on existing LGG gear grinding machines.
