If you really want to hear the "touch touch touch" of the grinder on the valve, just take them out of the chuck, turn them 180 degrees, and chuck and grind them again.

Repeatability is an issue in the real world. There are machines of better repeatability - but there is no PERFECT repeatability.

The real question is how far out of concentric can you truly tolerate.
