Had all my Triumphs' original discs turned to remove remaining chrome, no problem. The engineers/machinists that did them were all aware of the requirement for both surfaces to be true to the inner mounting face and to each other, and they were/are so.I've read that they should be ground only, not turned,
Can't make any comment on the particular shop listed but last shop I worked at was owned /run by an old machinist. He ground all discs including floaters.I used Disc Brake Reconditioners to Blanchard grind (and drill) at least 20 discs over the years. 100% satisfaction and BEAUTIFUL work.

Hi Woodsie.I'm thinking about getting a brake disc turned to remove what chrome is left and to true it. I've read that they should be ground only, not turned, is this correct?
If they were going to grind, the chrome wouldn't matter. A local brake place only has a skimming machine. According to this tech bulletin you can machine a cross drilled rotor.Please note, whether the shop skimmed or ground the surface, I don't know.
The main thing is, that in my case the chrome needed to be first removed.
