**Verdict:** inspect

Used DMG Mori NHX 4000: $79,900–$154,900 observed used across 4 listings. The documented cost risk to price in: Pallet pool hydraulics. Buy only after inspection.

**Observed used price:** $79,900–$154,900

**Documented failure risks:**
- Axis rigidity / rapid acceleration: Aggressive factory rapid-acceleration settings (tuned for cycle time) can cause the machine to shake at full-speed rapids; technicians commonly reduce Fanuc acceleration parameters to control it.
- Pallet pool hydraulics: Intermittent pauses while tilting the automatic pallet changer down after moving a pallet, traced to hydraulic cylinder binding, a manifold valve fault, or a faulty proximity switch.
- Chip conveyor / control: Owners report the chip conveyor struggling to keep up with high chip volumes, plus control input latency, as recurring reliability complaints on NHX-family machines.
