Feed with the table and not with the quill.



and lock the quill

I'd just use the quill powerfeed, starting on .0015" (assuming a BPT-type
mill) and perhaps 100 RPM, just to see how everything's running. Then
increase as the machine/setup/workpiece will allow.

I've found that the nice thing about large machines like mills and radial
arm drill presses is the powerfeeds, as far as drilling/boring is concerned.
I've used a carbide endmill to plunge-drill out a broken reamer (someone
else broke it, not sure how) on a radial arm drill press using the
powerfeed. While I wouldn't even attempt it, I'd be surprised if the endmill
would have gotten .005" into the material with handfeeding. Unbalanced cuts
are very intolerant of an operator's flimsy arms.
