My conversations with the tour club techs I know support Arnie's findings - the majority are using a 3M Scotchbrite wheel (same as they use to finish bore thru soles) to 'mill' the face. Some more elaborate techniques were discussed, but these were all done at OEM test facilities, not in the tour trailer.
Understand that very few tour players actually use drivers with milled faces (most of these guys hit it far enough - they're all looking for straighter, not longer), especially when you consider the durability issue. These guys generally like to find a driver that they are happy with, then USE it as long as possible. And, they tend to do more than hit a few daily warmup drives, 14 or so on the course, then pack it up till tomorrow. A driver with a max USGA COR face AND milling that really effected distance would last weeks at most for about any pro - not what any of these guys are looking for. If anyone shops ebay or other websites for equipment, you'll see a good share of 'tour van milled' drivers listed. These are almost all bogus, IMO, simply lies to attract buyers.

TECHNIQUE ON HOW THE TOUR VAN GUYS ARE MILLING, (SANDING, THINNING) DOWN THE FACES OF DRIVERS. can YOU TELL ME WHAT PIECE OF MACHINERY ARE THEY USING
Spoke to a few Tour Van Guys, they are using a 3M finishing wheel on a buffing motor, sweeping back and forth, concentrating on center of face. They don't know how much material is being removed either, one said "if I remove too much, the face cracks and the manufacturer replaces the head." Got some heads you want to throw away, go to it. I question the practice because you are reducing the depth of the grooves and may be causing the head to non conform to COR rules. What are you gaining? Experience and dirty hands! I think it's all part of the "dog and pony show" I get better results by applying a thin layer of snake oil and rubbing it in with a piece of specially formulated cotton tee shirt. Grunt a lot while doing this, wipe the sweat from your brow, and charge accordingly!
