Off the subject of robots, I came across this...

... and something about just seems a little odd.

The material is said to be Toolox 44 but at the speed it is cutting it, with no coolant, I cant see how? It isn't sped up it just jumps to key points. And the way the machine is behaving in how it cuts seems unusual as well. Its not doing the typical layer by layer pattern. Is this common for CNC mills these days or is this a special/new type?
