Sherline mini mill CNC rotary table
Part of me is wondering if the jaggedy edges are from my not feeding the material fast enough. The edges don't appear jaggedy as much as melted. Maybe the bit spinning for too long against the aluminum causes it to throw tiny spurs of melted aluminum? Maybe not, but when I polished this thing (in later pics) with a Dremel metal wire brush polisher, I got what appear to be little melted fragments.
