cnc lathes and mills are used for what exactly? any chance this type of craftsmanship being replaced by tech?

I am a CNC machinist. CNC lathes can be used to produce anything a manual lathe can. This is also true of CNC lathes.
CNC machines are much more economical to use than their manual counterparts (at least for high-volume production) due to their repeatability, their lower per-piece cost, their ability to be left unattended, and their ease of control. Once programmed and debugged, a CNC lathe or mill can theoretically produce millions of identical pieces, provided the cutting tools (Titanium-carbide inserts on tool steel cutting tools) are maintained.
By the way, the lathe is the only tool that can be used to reproduce itself.

How do I build a model Jet?

ok….. I have been thinking about making a model jet engine and I have a rough sketch in my head, but the only problem is, I dont have a lathe or a drill press or any of those fancy machines so how do I make the fans? Its simple enough making the casing and combustion chumber I am just wondering how to make the fans without using a car turbo charger as they look as ugly as hell and are inefficent. Or could someone direct me towards a good free plans site for jets?

You make those parts by getting the fancy equipment or by spending years learning to hand file and balance those parts, if you want the thing to actually run. In operation a turbo jet spins at tens of thousands of rpm, so the bearings have to very high speed, the shafts absolutely straight, and the fans concentric and balanced to a fraction of a percent.
If you want an operational engine you would be better off buying a kit. And safer.
