Aluminum finish

[Boyan Silyavski]

I saw a interesting video on You tube . Demonstrating a machine, which more or less is similar to a good DIY heavy duty router.

So at the end they used 1 flute 6mm ball nose cutter to finish the aluminum. I did not know they even existed. I like very much the result and i wonder if sb. uses the same technique and illuminate me about that last pass, depth of cut, %, speeds, etc.
