Aero Engine as well as tool and die components are routinely subjected to extremely high levels of stress. This is why one key quality criterion is their material strength. High levels of strength, meanwhile, also dictate that the material in question will be difficult to machine. One technique of machining materials independently from their strength is spark erosion. The technologies of wire EDM and sinking EDM allow the high-precision production of geometrically complex components with very small interior radii. With the EDM technique, it is also possible to manufacture components with high-quality surfaces and low levels of subsurface damage.
The Fraunhofer IPT is using all of its skills and experiences with the application of EDM strategies in the development of innovative practical approaches, aiming to reduce subsurface damages to a minimum, to increase the components‘ technical life spans and to decrease the costs of the manufacturing operation. In our cutting-edge array of sophisticated equipment, we can test the results of our research departments and further deepen our understanding of the underlying physical processes, ultimately converting our knowledge into practical applications for mold and die manufacturing, engine production, precision engineering and medical technology.
