Everything is fine. Turning and milling is a skill as its name implies. It can be used as a milling machine (that is, a machining center) or a lathe. Of course, the price of this kind of equipment is much more expensive than that of the general CNC machining center, which is why you are worth it. The main difference is that the A-axis which is consistent with the machining center can rotate at high speed and can be used as a lathe. Moreover, numerical control is comprehensive, and many difficult, inclined and high-precision machines can be processed, but turning-milling compound machine tools can't.
