The production of a large volume of parts with extremely high quality has been a key feature in the production of automotive transmissions for decades. Developments in both the marketplace and technology, however, are continuing to change production at a very fast pace. For example, the number of gears needed for the production of our cars has been rising. This increase in quantity is pushing the production volume of gears even higher. At the same time, the competition from new market participants in Asia is intensifying.
Vertical production machines are EMAG’s territory. It all began with the VSC series, which laid the foundation for the successful machine concept of the vertical pick-up turning center. This machine concept runs through nearly the entire product range of the manufacturer, and it takes on its latest form in the VL series.
For years, the focus of car designers has been the steering gear. The system has been complemented by complex secondary drive systems. Drivers are now clamouring for steering systems with even more precision. In order to meet this demand, the production of associated components also changes – it has to become more efficient and more precise.
In the automotive industry, one trend has been consistent for years: Passenger vehicle transmissions are becoming smaller and lighter, although the number of speeds—and of toothed gear components—continue to increase. How does the entire assembly not become heavier? The answer becomes obvious by taking a closer look at the individual components. A gearwheel, for example, consists of two components that are joined by laser welding. This allows the design engineers to work without screws—allowing the component to become lighter.
Gears keep the world moving. They are found absolutely everywhere, in many different shapes and made from an extremely wide range of materials. From the tiniest, most delicate gears used by watchmakers, to gears with a diameter of 16 meters used in mines and the cement industry, where they drive gigantic mills and rotary kilns. Big or small, they all have one thing in common: they must satisfy the most demanding requirements.
The market for commercial vehicles has seen non-stop growth in recent years, especially in Europe. The implications for the manufacturing technology used can be seen in the example of the VMC 450 MT: This vertical turning/milling center from EMAG Leipzig Maschinenfabrik offers an unprecedented level of flexibility. A multitude of large and complex chucked parts can be machined on it in rapid alternation—made possible by keeping setup work to a minimum.
Massive workpieces and small batch sizes – in wind energy plants, commercial vehicle production or the aircraft industry these extremes can clash. The VM 9 turning center from EMAG not only provides a productive solution to these industry sectors, but also has the functionality to be loaded and unloaded automatically or manually based on the…
Schneto AG, located in idyllic Bennwil, near Basel, specializes in the production of turned parts up to 65 mm in diameter. The company has made a name for itself because of the outstanding quality of the parts it manufactures. Its output covers a broad range of parts, including parts for furniture making, for hydraulics and pneumatics, electrical equipment, automobiles and construction equipment.
