In the machining zone, each discharge creates a crater on the workpiece side (material removal) and a burn-off on the wire side (wear of the tool electrode).
The wire can be inclined, and in this way workpieces with tapers or with different profiles on the top and bottom of the workpiece can be produced.
There is no mechanical contact between the electrode and the workpiece at any time! The wire is usually made of laminated copper or brass and has a diameter of 0.02 to 0.3 mm.
EDM processes can also be used to machine extremely hard materials such as hardened steel, titanium, carbide and conductive high-strength ceramics, which are mainly used in the aerospace industry.
Wire erosion
Electrical discharge machining cuts a programmed contour into a workpiece using a metal wire (electrode). It is used to produce dies, molds and certain metal parts, for example.
Wire EDM is also often a cost-effective alternative for parts with complicated contours.
We offer conical machining (conical angle/height °/mm ±30/400) and workpiece lengths of up to 2,000 mm as special features.
Die-sinking EDM
Die-sinking EDM reproduces the shape of a tool called an electrode in a metal workpiece. Injection molds for plastic parts are very often machined using die-sinking EDM.
The shape given to the electrode corresponds to that of the object to be cast later.
In the machining zone, each discharge creates a crater on the workpiece side (material removal) and a burn-off on the tool side (wear of the tool electrode). There is no mechanical contact between the electrode and the workpiece at any time. The electrode is usually made of copper or graphite.
Precise and inexpensive eroded parts
With many years of experience, we manufacture precise and inexpensive eroded parts for you on a contract basis. We work with high-quality wire and die-sinking EDM systems in air-conditioned rooms. We can create professional measurement reports at any time using our 3D measuring machine.
We use the latest CAD systems to program everything from simple 2D contours to complex ruled surfaces. Our interfaces: DXF, IGES, DWG
Wire EDM is often a cost-effective alternative for milled parts with complicated contours that cannot be ideally clamped.
