Benefits of Hydraulic Power in machine tools
Well I am not an authority on hydraulics, that being said hydros are used in Bullard VTLs, Warner Swasey & Gishlot lathes and some gear shapers.

Just a thought...CNC vs. Manual...
I get it ,I run a Lancer 2000 VMC 95% of time 70-80% of the time 2-40 production parts. The remainder I could do on a bridgeport style mill with DRO much faster and with much more ease. Guess it comes down to how many machines you are willing to have and type / size of parts you usally run. -
