How can we ensure maximum manufacturing productivity? What is the best automation system for our wide variety of parts? Which partner can reliably put our plans and requirements into practice? These are the kinds of questions that every manufacturing company aiming to increase its productivity has to ask. Kordel Antriebstechnik GmbH, based in the Westphalian town of Dülmen, found the right solution for its gearbox production with a pallet handling system from Liebherr.
In August 2019, trainees Fabian Altenried and Julia Fetzer participated in the Liebherr Summer Program at Liebherr Gear Technology Inc. / Liebherr Automation Systems Co. (LGT / LAU) in Saline, near Detroit. There, they ran the PLC programming course for pupils of the robotics course from the local high school, which was offered for the first time, and got to know the work routine at the Liebherr site. Fabian reports on his experience here:
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.
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.
Liebherr presents the latest member in the PHS Allround family, the PHS 800 Allround. It has a narrower design than the PHS 1500 Allround, which makes it ideal for automated loading of smaller machine tools while retaining the basic principle of modular design and universal applicability and expandability.
Karl-Heinz Klöble is responsible for putting large gear cutting machines into service in China. We spoke to him about his experiences there and what fascinates and motivates him in his unusual job – and why he’s too busy to retire yet.

From the manufacture of satellite antenna systems to medical technology and automation: precision gearboxes are at the heart of many applications in industrial production. The automation industry is booming, and with it, demands on both quality and productivity are rising—a challenge for many suppliers. Liebherr’s broad range of machines, processes, and expertise offers the optimal solution for every application.
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.
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.
Anyone who manufactures small batch sizes of complex components wants to perform as many work steps as possible with a single machine. This not only saves time and equipment costs but also increases the quality, provided that the clamping fixture does not have to be changed. Liebherr-Verzahntechnik GmbH offers a comprehensive solution for complete machining by integrating a tool changing system and a chamfering device while using the turning, drilling and gear cutting functions of the latest generation of Siemens controls.
A visit to the HMC Gears plant in Indiana kicked off an extensive project which resulted in the creation of a unique solution for exceptional demands: With the LC 4000, Liebherr forges new paths in large-scale gear cutting production and unites diverse machining methods in one highly efficient machine for the American gear specialist.
