I've settled on using Diamond Coated End Mills. Even though they're QUITE EXPENSIVE, I've read accounts that state that 4, maybe 5 Graphite projects can be eaked out of diamond end mills. This is where POSSIBLY only 1 out of conventional end mills, maybe not even that.
Here I thought that Graphite would be easy to machine. Like butter. It's tougher than I thought. Guess I was wrong. At least I'm accustomed to it.
Worse than that, I found like 400 lbs of EDM Graphite for FREE on Craigslist! By the time I called it was all gone. Oooooooh the agony.
Where dust is concerned, I'm thinking of building an enclosure. I'll pump coolant in to catch the dust as it emerges from behind the cutting tool. I've seen accounts of this working as well.
Thanks for all the input.
My new question is whether or not I can cut Graphite on a CNC'd Sieg X2 Mill. The mill runs under 4000 rpm's. I don't know if that'll be an issue or not.
I do know that if it is possible, that it would kick serious butt!
