One thing worth noting, at work we grind thin walled exotic alloys like inconel and waspaloy and they really do resonate whilst machining,
I have made many Z axis but only ounce did I build one this way and that was due existing design issues(not my design), it was for a machine which exclusively cut HDPE so no big deal but the difference between my normal conventional way was clear when pushed hard.

The differnece between this and your work example is that the work machine didn't vibrate the material did which happens now imagine what would happen to finish if the tool was vibrating as well.! . . How do you stop or deal with that.? . . . . . Cut slower/shallower point being your making compromises you shouldn't have too just becasue of machine design
