Feeds and speeds for aluminum milling - Machines & Machining ...

We use that tools on our CNC's with speed up to 15000 rpm and 550 in./min at a depth of cut of up to .25. Of course the setup is more rigid than on a Bridgeport. You probably can run that tool (1.5 dia ) at 2700 rpm and at a feed of about 36 ipm at a depth of cut of .25 depth .You can add a bit of spraymist or some Kerosene as a lubricant.
