Most are very abrasive but you can go as fast as your spindle will
allow. It machines more easily than magnesium. I machined a lot of
thread-cutting electrodes from Poco 3 graphite a few decades ago
Easy-peasy. Don't be afraid of it.


Wicked messy though. Graphite dust everywhere. I bought some equipment
from a shop that did a lot of graphite machining and it was a dusty mess.
