PECM from EMAG: Move into the Fast Lane in Blisk Machining

Blisk (bladed disk) volumes in aircraft production are increasing massively. Large engines now have several of these high pressure compressors which are manufactured from a single piece of high performance, often exotic alloy materials. The efficient machining of these materials is therefore becoming a focal point for project planning with a wide range of potential methods and combinations thereof available, from mechanical cutting to water jet cutting. A recent study by the Fraunhofer Institute for Production Technology (IPT) and the Laboratory of Machine Tools and Production Engineering (WZL) at RWTH Aachen (Germany) has now shown that Precise Electro-Chemical Machining (PECM) from EMAG drastically cuts costs for users, particularly for dressing the component surface.

Solid-State Versus Gas Lasers – Modern Laser Production Technology for Powertrain Components

Even a few years back major manufacturers utilized standard CO2 lasers in factories for welding applications. Massive systems installed in separate rooms away from the actual production process supplied the energy for what, at the time, was relatively new laser welding technology. Developments since then have continued and modern systems increasingly use solid-state lasers, which deliver a range of major benefits.

Modular vertical hobbing machine VL 4 H – designed with the whole process in mind

Gears literally keep the world moving. They are found absolutely everywhere, in many different types and shapes and made from an extremely wide range of materials, from the tiniest, most delicate gears used by watchmakers to gears 16 meters in diameter used in mines and the cement industry, where they drive gigantic mills and rotary kilns. But no matter whether big or small, they all have one thing in common: they must satisfy the most demanding requirements.

EMAG at the AMB: Expansion of the Modular Product Range

The success story of EMAG's modular machines continues at AMB. The modular machine concept was introduced by EMAG in 2011 and has turned into a favorite within the market. Starting with a focus on the development of vertical turning machines, in recent years, we have witnessed the integration of the EMAG Group’s full technology portfolio into this new machine model. Now, in addition to vertical pick-up turning centers for chucked and shaft parts, there are also machines for gear cutting, induction hardening, and hard machining. Combined with the TrackMotion automation solution, EMAG now offers these modular machines as building-blocks for entire production lines. EMAG will be introducing two new modular standard machines to the EMAG product line this year at AMB in hall 3, booth D32.

VMC MT series: Universal solution for large chucked parts provides maximum flexibility and efficiency

The market for commercial vehicles has seen non-stop growth in recent years, especially in Europe. The industry association ACEA estimates that around 2.08 million new trucks, vans, and buses were approved in the EU in the past year. This represents growth of more than 12 percent on the previous year. Demand for heavy vehicles with more than 16 metric tons was especially high. For the manufacturers, however, this positive development goes hand in hand with a growing technological challenge. The customers are demanding mobility solutions that are more precisely tailored to their fields of operation. For example, alternative drive systems and more efficient conventional drives are both becoming increasingly important. The indirect consequence is that product cycles in production are becoming shorter and shorter; the number of part families being produced is also rising in many plants. 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.

PICO generators from eldec: Mobile induction heating with maximum efficiency and precision

Contactless, fast, accurate, and precision-controlled: These are the essential advantages of induction heating. The technology can be used whenever workpieces or components are heated to a pre-determined temperature for further processing. The areas of application for induction heating are diverse, ranging from the automotive and machinery industries to power generation and electrical equipment. The experts at the eldec, an EMAG subsidiary  based in Dornstetten, Germany, have a precise understanding of this wide array of applications. For over 30 years, eldec has been developing sturdy, high-quality energy sources for inductive heating. With the new PICO series, these specialists now offer their customers an extremely compact and cost-effective device with a very broad range of performance capabilities. It is extremely easy to handle — a crucial factor for portable use.
