  Tips on milling brass The Home Machinist!

  · I have little milling experience on brass, but considerable turning experience. Biggest problem on the lathe is parting, as the tool wants to dig in, just compensate with slower, steady feed. Not sure how this will translate to milling, but my gut is faster speed, slower feed. Faster speed to me is 2500 RPM.
