EDM die sinking reproduces, in a metallic workpiece, the shape of a tool called electrode. Injection molds for plastic parts are very frequently machined by die sinking.

The shape given to the electrode is that of the object that is going to be molded. In the machining area, each discharge creates a crater in the workpiece (material removal) and an impact on the tool (wear of the tool/electrode).

There is never any mechanical contact between the electrode and workpiece. The electrode is usually made of copper or graphite.

EDM wire cutting uses a metallic wire (electrode) to cut a programmed contour in a workpiece. Extrusion dies and blanking punches are very often machined by wire cutting. In the machining area, each discharge creates a crater in the workpiece (material removal) and an impact on the tool (wear of the tool/electrode). The wire can be inclined, thus making it possible to make parts with taper or with different profiles at the top and bottom. The wire is usually made of brass or stratified copper, and is between 0.02 and 0.33 mm diameter.

The Drill 20 is a production machine designed for the drilling of parts in hard materials such as hardened steel or carbide. Its drilling capability ranges from 0.3 to 3.0 mm diameter through a depth of 200 mm. Particularly simple and easy to use, the 3 axes (X, Y, Z) numerical control makes it possible to program a series of holes for fully automatic machining.
