It’s vibrating at its resonant frequency due to asymmetrical loading. Since the load is relatively small it can readjust itself when the chatter becomes really loud. If it was a large load that was off-balance, the chatter would be a consistent beat (sixteenth notes?) that would become increasingly loud. Additionally, the load is too small and heavy to evenly distribute itself, ensuring that it will make the machine go off-balance soon after it corrects itself. This is why it sounds like several sixteenth notes followed by a rest of varying length followed by more sixteenth notes.Some language NSFW. Via Synthgear.
