Really impressed with the skill of these guys. From start to finish a “well forged”organization. This takes a tremendous amount of skills.

What wonderful skills they have all working harmoniously with one another, each one knows exactly what his job is, and when to move in sequence with the others, we’ll done to you all, brilliant display of your skills!!

The depth of cut can be increased considerably by grinding a suitable geometry for the tools. It looks like a random piece of brazed carbide they are using. A properly ground high-speed steel or cobalt cutter would not only cut several times faster (depth of cut) with adequate chip breaking, but would also leave a superior finish. It seems like most of the time just a pointed cutter is used without lubricant/coolant. And get a damn live center or at least a dead center that resembles the shape of a cone. Interesting video nonetheless.
