Planetary gears have been around for over 200 years – the first one was used in a steam engine at the beginning of the 19th century. The technology is still indispensable in cars, for example. What distinguishes the whole thing in detail and what are the differences in design?

In the heart of the Eifel region, around 50 kilometers from Koblenz, Bharat Forge Daun mechanical production works at the highest level, producing extremely precise, rotationally symmetrical series components, among other things. This means that challenges like difficult surfaces and positional arrangements are common. Several EMAG machines are currently being used in the production of a stator housing for electromobility – with a focus on process reliability. In the following interview, Christoph Steffens, Head of Mechanical Production at Bharat Forge Daun, explains the reasons for using EMAG machines and why EMAG service is so important.
The integration of robot technology into manufacturing processes is playing an increasingly important role in the modern industrial landscape. Jan Gotthold, Product Manager at EMAG Maschinenfabrik, provides an exciting insight into this area. Using EMAG’s drive shaft production line as an example, he demonstrates the key benefits of this technology.
The monthly number of new registrations of e-cars in Europe is currently increasing – and with it the required quantities for the e-drive components. The example of the supplier Linamar Technology Hungary shows how the production task behind this can be solved effectively. The e-drive specialists have recently invested in EMAG machines for the production of shafts and gears. A conversation with István Bíró, Project leader at Linamar Technology Hungary, about the new solution at the site in Békécsaba.
With around 15 percent growth per year, the Czech supplier ZLKL has an impressive success story. Advanced production technologies with automation components play a decisive role in this. For example, around 25 EMAG machines are in operation at ZLKL’s Czech sites. Karel Zeman, Senior Manager Machining at ZLKL, discusses his company’s formula for success.
For over 30 years, Bäringhaus & Hunger, based in Grünhainichen near Chemnitz, have been active in the part manufacturing industry – experiencing growing success with the production of high-precision turned and milled parts. About 90 percent of orders received at Bäringhaus & Hunger come directly from suppliers in the automotive industry. From almost the very beginning, EMAG has played an important role in this as a mechanical engineering partner, and currently have over 20 machines on the Bäringhaus & Hunger shop floor. How did this partnership develop and why is it still so important today? We spoke with partners, Matthias and Sebastian Hunger, the second generation of the family to run the company, about the secret to their company’s success.
Interprecise Donath GmbH, based near Fürth, Germany, develops and produces rolling bearings that are used in a variety of machines and gears – an extremely precise task that involves just a few micrometers and requires special surface qualities. For about three years, VL vertical lathes from EMAG have been used for this machining, achieving lower unit costs in the soft and hard machining of many components. We sat down for a conversation with Interprecise Managing Director, Christian Witte, about the market challenges and advantages of pick-up technology.

The VL 1 TWIN has set the new standard for the high-output, simultaneous machining of workpieces with a maximum dimaeter of 75 mm (3 in). This turning center has two main spindles in one machining area that are able to simultaneously machine two identical workpieces – resulting in substantially increased output quantities, and lower unit costs.
How can commonly mass-produced transmission components, such as planetary gears be produced even more efficiently? The EMAG Group provides a customized answer to this question with the development of the twin-spindle pick-up turning center, VL 1 TWIN. It machines two identical components simultaneously in the same machining area. This technology opens up a wide range of possibilities: When two machines are combined in a line, the planetary gear can be machined from two sides—and all that is completed with shorter cycle times. What exactly does the line solution for planetary gears look like?
