Why is it synced like that? Seems dangerous, and I don't know much about lathes but lighting synchronization doesn't seem something that would affect the mechanical parts being processed :)

Synced to the AC mains or a multiple thereof.

Layman's guess: Both were synced to the mains frequency.

Sounds accidental, but might be interesting to be able to see the workpiece as if stationary, while it’s turning at 1800rpm. Everything looks smooth under ordinary lighting.
