Copper VS Graphite Which Material is Better for EDM Electrodes? - Part 2
February 11, 2022 12:32 pm
Graphite takes the cake. Having worked with both copper and graphite for electrodes, Steve has discovered that graphite is overall more universal and cost effective for EDM work. This part 2/2 of graphite vs copper will explain why. Grab part one here.
The following topics are covered:
- Results from part 1
- Steve’s discoveries about each material’s performance
- Findings from copper tungsten experiment in part 1
- Why comparing cooper tungsten and graphite can be very difficult
- Copper and copper tungsten burning carbide
- Chipping / breaking of electrodes with demonstration on graphite and copper electrode
- Sucker systems to contain the mess from burning
- Graphite can support more detailing than copper… why does that matter?
- Burning ribs in an aluminum insert with graphite
- How graphite and copper differently affect EDM performance.
(Higher flow of current through a graphite electrode than a copper electrode). How does this affect cost? - Roughing electrodes of graphite vs copper and the given implications.
- Finishing electrodes of graphite vs copper and given implications
- Comparison of surface finish in the cavity of graphite vs of copper.
