Looks great!
What speed (rpm) were you cutting, and what size bit?
I'll use Castrol Stick Wax (easy to rub a light coat over the area to be machined) as it will help lubricate the cutter as it passes over the area.
That looks great! Often, when facing, I set up a 2" end mill and run the milling machine at 3 ipm for a very nice finish. I'm time sharing between the lathe, mill, and drill press.... so my ear tells me when the mill is done and time to flip the edge.
