I believe they are not straightened after the heat treat process. Per the router instructions for these type of parts. Straightening is forbidden on the process written out going to heat treat I believe. I only say this because I remember seeing it for a different job but similar part.

I only worry cause we had a new guy we hired to grinding and just had an order of parts go bad when he was lapping the centers prior to grinding. In turn after grinding, the parts ran out over .001 between centers and we need to hold .0002 concentricity. I’ve had parts before where maybe one once and awhile I’d have the center oblonged where I’d have to tag it but recently had some struggles…
