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.
Cost not yet verifiedIntermittent 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.
Cost not yet verifiedOwners report the chip conveyor struggling to keep up with high chip volumes, plus control input latency, as recurring reliability complaints on NHX-family machines.

From the research record
- FAILURE (2026-09-05, agent-fetched, Claude spot-verified sample): Axis rigidity / rapid acceleration: "NHX rapid accelerations have gotten more and more savage over the years in an effort to compete on cycle times. I've had techs tune down the accelerations on brand new machines." https://www.practicalmachinist.com/forum/threads/mori-shakes-aggressively.425544/
- FAILURE (2026-09-05, agent-fetched, Claude spot-verified sample): Pallet pool hydraulics: "The unit is pausing while tilting down in the extended position after moving a pallet." https://www.practicalmachinist.com/forum/threads/intermittent-pallet-pool-hydraulic-problem.429635/
- FAILURE (2026-09-05, agent-fetched, Claude spot-verified sample): Chip conveyor / control: "The Iron is very good, but the chip conveyor is the biggest hunk of shit around. It just can't keep up with high volumes of chips." https://www.practicalmachinist.com/forum/threads/dmg-mori-experiences-and-impressions.381657/page-3
- NOTE (2026-09-05): The 2012 unit is listed under the pre-DMG-merger name 'Mori Seiki NHX4000' but is the same model line as the 'DMG NHX-4000', so both are counted as exact matches. A different, larger model (NHX5000, $79,900, 2012) also appeared in results and was excluded.
- NOTE (2026-09-05): theequipmenthub.com returned no results for this model.
- MARKET (4 real exact-model listings combined, 2026-09-05): revelationmachinery.com: $154,900 (2019), $79,900 (2012, listed as Mori Seiki NHX4000 pre-merger name, same model line); eBay: $89,500 (2017), $99,999 (2017 Gen 2). low $79,900 / median $94,750 / high $154,900.
