Feeds and speeds for aluminum milling - Machines ...

In general, rough end milling aluminum is best done with two or three flute tools with lots of chip clearance. I've had best success with relatively shallow cuts coupled with high speeds and feeds. You have to keep coolant at the tool tip - difficult with deep cuts and lots of chips. Just for facing, think about face mills with carbide inserts.
