Selección de un material de electrodo EDM

(Selección de un material de electrodo EDM)

El material del electrodo juega un papel clave en el mecanizado por electroerosión. Es necesario considerar varios factores al seleccionar un electrodo.. El primero es el material en sí..

The most common electrode materials used in EDM applications are graphite and copper. Graphite is the most commonly used material in the United States, while copper is the most popular in Europe. It is important to understand the difference between the two types of electrodes.

Graphite is a non-metallic material with excellent electrical conductivity. It also has good machinability and thermal properties. It is available in many grades. Sin embargo, a high-grade graphite can be costly, while a lower-grade grade can be more economical.

For the most part, the best finish results are obtained when an electrode has a combination of materials. Por ejemplo, a premium grade electrode can be made from a graphite and a tungsten alloy. In addition to the quality of the materials, the machining process will need to be carefully planned.

Another consideration is the cost of the electrode material. This will vary depending on the machining process. There are many variables to consider when determining the true cost of an electrode.

A good EDM electrode material should be low cost, with a high melting point and good machinability. Aside from these characteristics, an electrode should have a high electrical conductivity.

A metallic EDM electrode is usually a copper or brass. They are not used for very detailed work, and have a lower cut speed.
