Can a 4th-axis CNC mill essentially do CNC lathe turning?

I am a newb to the world of CNC machining so forgive my ignorance, but I want to know if a 4-axis CMC mill can essentially do the equivocal operations of a CNC lathe? What is confusing me is that the "4th-axis" is a rotary table head and tail stock that sits on the mill table, so does this mean then that you have the capability of turning operations with it? I mean aside from the fact that the tool bit of a lathe and the end mills of a vertical mill sit in different places relative to the stock, isn't the basic motion created by the rotary table identical to that of a lathe thus making turning operations at the least similar if not identical?

some what it is the same yes but you don't get the rpm meaning that you won't get the speed in turning of a lathe for stock removal and constant speed to feed also toque and HP will be down and the time factor to over come the HP and toque will go up meaning everything will be done at a much slower rate. A 4th axis is more for contouring then lathe work they do sell machine tools that are called MAC turns that are a combination of a full lathe and a mill to over come this but of course the price doubles for the reason you are buying two machines in one and in any case you lose the Leigh of your work one more thing you can't get in close to the head or tail stock for the reason of the milling head unless you use a longer tool shank that will also slow down the final out come
Hope this helps you
