The HLC 150 H horizontal gear cutting machine by EMAG KOEPFER is the perfect complete solution for machining workpieces up to module 3 with a maximum length of 500 mm (20 in). It not only features all relevant gear cutting technologies such as gear hobbing, skiving, screw milling and worm skiving, it also includes press deburring and chamfering integrated into the machining area. As a result, an extremely wide range of workpieces can be finished without burrs – including gear and anchor shafts, steering pinions, planetary gears and worm gears.
The transformation in the automotive industry is coming fast, and those affected should prepare now— this was the primary message at the 2019 EMAG Technology Forum. The event provided a lot of food for thought for attendees. Which key messages stood out?
The German Federal Ministry of Economics says that small and medium-sized enterprises (SMEs) are “driving economic success”—an assessment confirmed by a variety of research. The fact that innovative businesses, like EMAG, play a central role in this “driving force” is reflected “Axia Best Managed Company” award EMAG recently received.
In a traditional automatic transmission, a torque converter is installed between the engine and transmission. This core component contains an impeller, turbine wheel and a guide wheel. Driven by the engine, the impeller blade catch oil in the housing which creates a flow that will delayed drive the turbine wheel. This principle ensures a smooth startup and separates the drive train from the engine’s vibrations (referred to as engine irregularities).
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.
According to a new study by PwC, an automotive consultant firm – there are five dimensions that influence change in the automotive industry. The car of the future is electric and connected, increasingly autonomous, more integrated in sharing concepts and models are updated on a yearly basis (!)—making eight year model cycles a thing of the past. How can such a fast and radical change be implemented on the shop floor? What happens to the old machinery and to the existing production lines? A discussion with Markus Woitsch, Head of the EMAG plant in Eislingen, responsible for retrofitting and retooling, reveals that the answer relies not only on investment in new machines – but also retrofitting. The specialists at EMAG will ensure that existing machines and production systems are prepared for changing manufacturing processes with the help of some conversion work – offering an attractive alternative to purchasing new equipment.
Historically, the power of a car’s engine was dependent on the number and size of cylinders – today, that’s a thing of the past! Electronic engine control, turbochargers or compressors are responsible for the overall performance. The turbocharger has a particularly important role—a Swiss invention dating back to 1925, the turbocharger was used to considerably increase engine power. What distinguishes this component, why is it increasingly important and what are the benefits of using electrochemical machining? —Five interesting facts about turbochargers:
The Swiss company Humbel has been involved in gear production since 1928—specializing in particularly sophisticated types of gears and transmission components, eventually evolving into a full-service supplier. At their facility in Kradorf, approx. 20 kilometers (12 miles) from St. Gallen, they produce both individual parts as well as complete assemblies. The company recently expanded their machine inventory to include a VL 4 vertical turning center by EMAG. — We spoke with Alex Humbel, Managing Director of Humbel Zahnräder AG in Kradolf, on the challenges facing gear producers, the importance of E-mobility, as well as their company strategy.
In many ways, the production of large components presents a particular challenge in manufacturing. Used in commercial vehicles, large transmission, or wind power, these parts are large – making them difficult to handle and slowing down production speeds. Adding to the production challenge is the additional technological requirements being placed on the parts, as well as the demand for improved reliability and precision, with decreased costs per piece. All of which needs to be achieved while improving process speeds.
Which sector of industry is the most innovative in Germany? A very comprehensive answer to this question has been provided in the report entitled “Innovation in the German Economy” issued by the Center for European Economic Research (Zentrum für Europäische Wirtschaftsforschung GmbH, ZEW). The current issue rewards automotive manufacturing, among others, with a good score. According to the report, the automotive industry has the highest amount of innovation in its production (48.3%). Innovation is fundamental to the automotive industry’s economic success. Additionally, the industry’s “innovation expenditure” identified by the ZEW is increasing. In 2016, this was valued at 47 billion euros and, according to estimates; it should increase to nearly 55 billion euros by the end of this year.
