Speed and feed for surface milling

 · 25. Through my experience''s, I''ve found that sticking to the manufacturer''s sfpm and cranking up the feed is normally the way to go. I use a lot of 1/8 ball nose end mills @ 12k rpm and upwards of 150 - 200 ipm. Since the finish shouldn''t be taking a lot of material off, you still need to produce a chip.
