Best graphite for roughing

2020/12/7I've never actually heard that fine grade graphite doesn't rough well, however using a lower grade graphite material is more economical for roughing purposes. We generally use POCO EDM-100 or equivalent for roughing in our shop. Lower grade graphite will tend to

Strategy of High Speed Machining of Graphite Electrode and the Principle of Optimum Selection of Machining Parameters

2017/11/20Graphite electrode is widely used in metallurgy, electric furnace, EDM and so on, because of its high high-temperature strength, low thermal expansion coefficient, good machinability and excellent heat and conductivity. In the aspect of EDM, the development of new

Copper Tungsten Properties Make for An Ideal EDM

2013/3/19When you think EDM electrode materials, you probably think graphite. Beginning in the early 1950s, when the material first flooded the electrode market, and continuing into today, graphite is the material of choice for 90% of US-based EDM electrode applications.

Electrolysis with Graphite Carbon Anodes

EDM (also called spark machining or wire erosion) uses high currents that jump from the electrode to the workpiece to slowly carve away a complex pattern in a hard material. As such, a manufacturer can cut a pattern on a relatively easily-machined material, such as graphite, and reproduce the result on the difficult-to-machine material, such as titanium.
