Electro Discharge Machining: what’s it about?

EDM is a metalworking process commonly used in industrial fields. It is based on the erosive properties of electrical discharges and can be applied exclusively to conductive materials such as metals.

In recent years, thanks to the rapid development of electronics, Electro Discharge Machining has become one of the most commonly used processes in industrial fields, in particular for the production of stamping dies.

Depending on the type of application, two different procedures can be used:

  • Electro Discharge Machining (EDM);

  • Wire Electro Discharge Machining (WEDM).

In both cases, this type of process makes it possible to work on particularly hard metals, creating dies in all desired geometrical and volumetric shapes.

Balzarin: a leader since 1978 in the production of stamping dies using EDM

Balzarin in Verona was one of the first company’s in Italy to create an EDM department in 1978, now equipped with technologically advanced Electro Discharge Machining equipment. Operations for third parties are performed with special consideration of the component’s application in order to proceed in total safety, applying the correct couplings and tolerances.

The company’s machines can perform operations on pieces with maximum dimensions of 600×500 h400, with high level surface finishes equal to Ra 0.2.

The company successfully operates not only in the territory of Verona, but also in the provinces of Vicenza and Trento, serving as a point of reference for all of north eastern Italy.
