ECM (Electrochemical Machining) is being used for a growing range of industrial applications. To date, deburring is customary, but ECM could replace traditional chip-removal manufacturing processes as a better alternative. In the interview, our two ECM experts Fazli Yilmaz and Franz Gross from EMAG ECM explain what ECM is all about.
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).
1. Why do cars even have differentials?
There are no cars that don’t have differentials in them—otherwise we would be driving through tight curves with the wheels spinning and tires screeching. This essential component is located in the center of the drive axle, where its function is to make sure that the two wheels can turn at different speeds when driving around curves, while nonetheless having exactly the same propulsive power. The torque of the motor is always divided in a fixed ratio.
By the way: All-wheel drive vehicles have a differential on each axle, plus a central differential that distributes the engine power between the axles in a given ratio.
For over 50 years, Kordel has developed a variety of drive systems and transmissions used in agricultural and construction equipment, as well as industrial trucks. This is a task that requires both robust machining and precision, simultaneously. The family-owned business with its headquarters in Dülmen near Münster, Germany relies on the competence of its employees, flat hierarchies and a high level of integration with a “state-of-the-art” machine system. For over 20 years, EMAG’s pick-up technology has played a major role at Kordel. More than 17 production solutions from the Southern German machine builders are used at the production sites in both Germany and Poland. The most recent additions are two VLC 200 GT turn-grind centers. Below is a conversation we had with the Kordel Managing Director, Johannes Kordel, about the success of his company, and the important part mechanical engineering has played in it.
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.
With the introduction of EDNA, EMAG has developed a complete ecosystem for digitizing industrial production. This required strengthening bonds between teams across company boarders – in addition to the EMAG subsidiaries, diverse external digitization specialists were involved. For this reason, we knew that we had to invite several different people to join this conversation: Peter Strohm, Business Development Manager IoT at EMAG, as well as Ricarda Schuhmann and Lukas Siegele from our partner intuit to tell us about the development process, the possibilities offered by EDNA and why they are so happy about receiving this very special award.
The VLC GT series is one of the most successful new product developments for EMAG in recent years. The combination of the proven pick-up automation system, vertical machining operation and the option of using different technologies for hard machining in the spacious machining area, has made some fantastic production solutions possible.
With the VLC 350 GT, the next biggest expansion stage is being launched. We spoke to Marina Manger, assistant team leader of the TPM-1 application team, about the new machine and the ideas its development was based on.
EMAG eldec is breaking new ground in the production of inductors for induction heating and relies on the latest manufacturing methods, such as additive manufacturing.
We discussed the advantages this provides and the new opportunities this opens up with Kadir Yilmazli, who is responsible for ongoing development in this area as a development engineer for additive manufacturing at EMAG eldec.
The scroll-free turning of rotor shaft sheet metal housings has a number of advantages over the traditional turning process. For one, scroll-free turning provides significantly higher feed rates per revolution, leading to a reduction in overall cycle time. Machine time is also reduced by using the entire cutting edge of the tool – providing the additional benefit of improving tool life. This technology has also proven to achieve significantly better surface qualities.
