A graphite electrode is primarily made by Wire EDM. Wire EDM cuts conductive metal with a travelling charged wire that erodes a precise profile right through the part. Below is the full route to make a graphite electrode, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.
Step by step
How a graphite electrode is made
The usual route, raw material to finished part. The amber step is where the graphite electrode gets its basic shape.
Stock
Prepare the conductive or sheet stock for the graphite electrode.
Heat treatment first
Harden the material before cutting: EDM cuts hardened metal with no distortion.
Tooling n/a Tolerance can distort Lead days
Wire EDM
Cut the graphite electrode to its precise profile with no mechanical force.
Tooling None Tolerance ±0.002 to 0.02mm Lead days to weeks
Deburr and finish
Remove the recast layer or edge burr and finish as needed.
Inspection
Check the profile and surface against the drawing.

Cost
What a graphite electrode should cost
Wire EDM for precise 2.5D profiles in hardened/conductive material; great for low volume, no custom tooling.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for a graphite electrode at your volume, in your currency, are in the dossier.
