I had this same issue on my S10 and it was caused by too much tension on the bearings when I re installed the hub nut for the repacked bearings.
(I don't think this can happen on an Accord )

However that said, did they balance the rotors after turning?

You will find that most higher end rotors have weights on the viens or rear face for balance. Turning your rotors may have taken off too much metal and put one or both out of balance. Either have them rebalanced or just get new ones.

I rarely if ever turn my rotors, I find that 99.9% of the time they are within service limits. (purchase a cheap set of dial guages and micrometer from a tawain tool place, priceless IMO) If that is the case most brakes pad mfg. suggest not turning the rotors. Turning most newer rotors just leads to premature warping of the discs.
