Precision manufacturing by wire & sinker EDM

For us, no component is too delicate, no number of pieces is problematic and no requirement is too ambitious. From the first draft to the final product, we design, develop and manufacture precision parts and assemblies according to your drawing or idea.

What is EDM?

EDM means electrical discharge machining. There are two different EDM processes, wire EDM and sinking EDM.

In wire EDM, the contour of the workpiece to be machined is melted with high precision by means of a brass wire. This is done by using the ablative effect of electrical discharge between the wire and the workpiece.

Die-sinking EDM works on a similar principle. However, no wire is used here, but an electrode specially adapted to the contour. By moving the electrode closer to the workpiece, the geometry of the electrode, which was previously produced in the positive, is burned into the workpiece.

Advantages of EDM

Where other machining processes reach their limits, EDM with its numerous advantages opens up completely new possibilities. Due to the non-contact machining, hardly any resistance forces act on the workpiece. This is why the best surfaces and a precision of a few thousandths of a millimeter can be achieved even with filigree parts. Highly complex contours with the smallest inner radii are just as little a problem for us as the material hardness of the workpiece to be machined.

Applications

Wire-cut EDM and die-sinking EDM are used in tool and mold making. Medical technology, mechanical engineering, aerospace technology, watchmaking and numerous other industries where the highest precision is required for complex contours.
