Eroding

When it has to be particularly precise

Eroding for workpieces with the highest precision

Using modern CNC-controlled eroding machines, even extremely hard materials such as titanium and hardened steel can be precisely machined, where other machining processes reach their limits. Due to the high precision during eroding, components with filigree contours and complex geometries and bores are possible.

At Robtrix you can access a wide range of wire and die sinking EDM with up to 5 axes.

Briefly explained

How does eroding work?

Eroding is a machining method in which material is removed by means of electricity. A distinction is made between the two processes of wire-cut eroding and die-sinking eroding. In principle, any current-conducting metal such as aluminum, steel, copper, brass or iron can be machined.

In eroding, an electrode is moved to the workpiece at a small distance without touching it. Within the narrow gap between the object to be machined and the electrode, an electric current flows that generates extremely high temperatures between 8,000 and 12,000 degrees Celsius. This results in material removal by discharge via sparks.

How much material is removed depends on the polarity, gap width, duration and intensity of machining, and other factors. Eroding as a machining technique is mainly used where highest precision and particularly tight tolerances are required.
