Used CNC prices swing widely for the same model based on hours, condition, control, tooling and where the market sits. A 15,000-rpm spindle, 4th/5th axis, probing, a bar feeder or a newer control can each add real money; high hours, worn ways or a dated control take it away.
Rather than a single 'book price,' value is a range off the real comp curve for that machine class. Pull a live value for any make and model free at The Machine Blue Book.
