I’m trying to figure out what kind of cutting speeds (drilling in
particular, but also interested in figures for milling) for silver
and various gold alloys, if it’s available. Does anyone have a source
for these figures?
I hit up Machinery’s handbook and I figure that the tables for
are a good starting point, but there is a pretty good range, e.g.
from 60 fpm for phosphor and commercial bronze, all the way up to 175
fpm for free cutting brass and bronze… Thanks for any help!
