Take a look at the finish I am getting when face milling aluminum with a 4-flute 3/4" end mill. See those wrinkles? The finish feels glassy smooth, but those wrinkles bother me.
I'm using a Sieg SX 2.7 mill. I've been very happy with it except for this. There IS about 0.0005" runout at the end of the spindle, so I think this is the problem. But the runout on my old mini mill was no better, and I got wrinkle-free finishes when face milling.
The finish when end milling is great, and the y-axis alignment is spot on (no head sag, from what I can tell).
So is this a consequence of the runout? Thanks for your ideas.
