Seems like more chatter than I would imagine an such a large machine? Or is that sound something other than chatter?

Makes me wonder how long all that machining takes, start to finish.

The sound of the first machine, shown in the video, would be from the cut chip. The sound of the second machine would be vibration. The tool holder is very long. Cruel industry: two workers making the same type of piece to find out who finishes first ...
