Ant specialists needed for the 1 kHz ant

[fluidistic]

Within a very quick google research, one reads that the jaws (mandibules I should say?) of leafcutter ants can vibrate up to 1000 times per second. Wikipedia doesn't say so though.
Anyway I wanted to see a slow motion video about the vibrations but didn't find anything. If you found one, please share it. I wonder what is the mechanism that can create such fast vibrations. If you know about this, feel free to share.

I am not an ant specialist, but I did some searching on the internet and found this article that might have what your looking for.

Atta Cephalotes stridulate during the cutting of leaf fragments by raising and lowering their gasters, so that a cuticular file located on the first gastric tergite is rubbed against a scraper situated in the postpetiole.
