Sinker EDM

Electrodes for sinker EDM machining are generally made from copper, graphite, or tungsten depending upon work piece material and electrode wear requirements. Our AgieCharmilles Roboform Sinker EDM machines are outfitted with a C-axis for orbital and helical machining, as well as tool changers to increase unattended machine time and minimize cost to our customers.

Why Choose Graphite for EDM Applications?

The material characteristics from graphite offer advantages that make it a popular choice for EDM application. This is because the material: is easy to machine. is very resistant to thermal shock. assures stability of electrode geometry during EDM operation because of the low coefficient of thermal expansion (3 times lower than copper).

Spark Erosion: Electrode Selection (Spark Erosion)

2014/9/22With spark erosion, EDM spark temperatures many times higher than copper's melting point, certain applications using copper electrodes suffer from unacceptable electrode wear. With the advent of graphite as an electrode material, superior metal removal rates have

Why use Graphite EDM Electrodes

2017/6/19Why use Graphite EDM Electrodes There has been a long standing debate about whether graphite or copper is a better EDM electrode material. One of main reasons people have historically used copper within Electrical Discharge Machining (EDM) is because it is

Selecting the Right Graphite Grade

2004/6/1In order to obtain this fine surface finish during the EDM process, graphite with a uniform microstructure and small particle size is required for the electrode. Since the cavity is a mirror image of the electrode and the final plastic part is a mirror image of the cavity, it is important to start with the best electrode material possible to obtain the best plastic parts.

Graphite Electrode Advantages

Graphite electrodes for sale are easier to process and the processing speed is significantly faster than copper electrodes. For example, the processing of graphite by milling process is 2 to 3 times faster than other metal processing and does not require additional manual treatment, while the copper electrode requires manual grinding.
