If you haven't machined it, it's a piece of cake. Do you know what

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.

If you are going to cut graphite...first thing you need is a fully
enclosed work space on your table. Second thing you need is a HEPA
filter on the vac system you install to get the dust OUT of your shop.

Third thing..is a separate room to do the work in..preferably one not
attached to the rest of your shop. That **** tracks like the plague.
