Ken,
Now you're talking a language I know, other than SHP Chevy's.
Nice finish on the part ( from what I could see ).
What feeds & speeds are you running on the first cutter?
How much stock per pass were you taking off? Were you
running air/oil mist, or just cold air to cool the tools?
You'll probably find this interesting. I just finished a
multi-year development project with a client for ultra
high detail - high speed machining in tool steel. We
just purchased six 3-axis high speed milling machines
for this project at well over $2,000,000.00
We'll be running in the 30,000 - 40,000 rpm range with
cutters down to 0.006 diameter. Yes, that's two times the
diameter of a human hair. Get this - run time for these
cutters is anywhere from 20 - 30 hours. What are we cutting?
All future US coin dies at the US Mint.
I'd love to be able to post an video of that process, but
then I'd be conversing to you guys from behind vertical bars.
