Retero GmbH > Home > Services > Wire Eroding / Electro-Discharge Machining

Our new rotary axis allows a wide variety of shapes, very fine recesses, filigree profiles, and small radii or surfaces on round parts – all of them contactless and without force effect on the workpieces. We use the rotary axis if deep, fine recesses or small corner radii on round parts are not feasible anymore.

The rotary axis comes with great benefits, especially in wheel dressing: we are able to insert profiles with finest inner radii of e. g. r = 0.05 mm. Thanks to this process, we guarantee both profile accuracies in the µm range and high concentricity. The only condition is that the workpiece has electroconductive properties. Spark-erosive machining comes with the great advantage that workpiece will not be scalded during the work process. Therefore, there are no structural material changes to worry about.
