The professional-level combination machine tool in the video is a far cry from the sort of combined lathe/mill/drill offered on the hobby market.
Looks like a very good heavy duty lathe with a good solid milling/drilling head AND a small shaper attached to the far end of the headstock, completely independent of the lathe bed, other than using the same power source.
The flimsy hobby machines have a small milling head perched over the lathe’s cross slide, which doubles as the milling table. Not the same thing at all.
I like the one in the video. Would be very handy in the home workshop. The shaper element is a bit small, but probably intended mostly for the often essential job of cutting keyways in shafts and pulleys.
