Start with the disclosure, because it changes how you should read everything below. Our research on used Okuma and DMG Mori machines produced exactly two dated price points across both brands, and no hands-on failure evidence on either. Not thin in places. Thin.
We are publishing it anyway, because "we could not find this" is itself a finding when the alternative is a competitor inventing a price table. But you should know which sentences here are sourced and which are reasoning, so we have marked them.
The two numbers we have
An Okuma GENOS M560-V, 2022 model year, at approximately $138,000. That is one dated point, extracted from a Machinio model page. Five listings were active on that page, running up to $139,500, with the rest showing contact-for-price.
A DMG Mori NLX 2500, 2017 model year, at approximately $174,900. Also one dated point. Also five current listings, and the other four all show "Contact Seller for Price": a 2017 NLX 2500SY, a 2019 NLX 2500|700 with live tooling and dual chuck, a 2020 NLX 2500T/700, a 2019 NLX2500SY/700, and a 2016 NLX-2500SY/700, all US-based.
One point is not a curve. It is a ceiling reference for a recent machine and nothing more. You cannot interpolate a 2014 machine's value from a 2022 comp, and we are not going to pretend otherwise by drawing a line through a single dot.
Compare that to what our Haas records support: VF-2 ranges of $8,900 to $12,500 for 1994 to 2008, $34,500 to $39,950 for 2010 to 2015, and $41,900 to $62,900 for 2016 to 2022. That is the difference between a market with price discovery and one without. Okuma and DMG Mori move in thinner, more specialist channels, and less of that trading happens in public. If you are used to pricing a Haas against a year band, this is a different exercise.
Configuration drives price more than year does
On the NLX line specifically, the submodel letters are not trim levels. SY means Y-axis plus sub-spindle capability. T means a built-in-motor turret. There are bed-length options, and live tooling on select configurations. Those change what the machine can do and, presumably, what it is worth, which is exactly why one undifferentiated dated comp is not enough to price against. A 2017 SY and a 2017 base machine are not the same product.
One caution on specs: the spec block Machinio surfaced for the NLX 2500 cites a 2005 model-year reference (380mm turning diameter, 1,000mm max turning length, 230mm X travel, 1,000mm Z travel). That may not represent the current generation of the machine at all. Verify against a real spec sheet for the year you are buying.
For the GENOS M560-V, what we could confirm across listings: 3-axis, CAT 40 taper, side-mounted tool changer with station count varying by listing, spindle speeds ranging from 12,000 to 15,000 RPM, and options for a 4th-axis rotary table, through-spindle coolant, high-pressure coolant at 250 PSI, and probe or tool-setter integration. We are deliberately not publishing the travel dimensions, because the extracted table's millimeter-to-inch conversions were internally inconsistent and we have not cross-checked them against Okuma's own sheet.
Okuma's in-house argument, and what it actually implies
Okuma's pitch is vertical integration. In its own factory-tour video for this machine, the company emphasizes that it builds its motors, encoders, drive units, and printed-circuit boards in-house rather than sourcing third-party components, and positions that against Fanuc-control and Siemens-control competitors. The control on the GENOS M560-V is Okuma's own OSP-P300M.
That is marketing content, and we are labeling it as such. It is not a failure-mode source and it is not evidence of reliability. But it is a sourced statement about how the machine is built, and it has a real consequence for a used buyer, which we will flag as our inference rather than as fact: if the control boards, drives, and encoders are Okuma's own designs, then board-level support and parts availability run through Okuma's channel rather than a broad third-party repair ecosystem. Whether that makes parts pricier, scarcer, faster, or slower than a Fanuc-control machine, we do not know. We did not price the Okuma parts channel, and we are not going to guess in either direction.
What it does mean is that "can I get this control fixed in ten years" is a due-diligence question on a proprietary-control machine in a way it is not on a Fanuc-control one. Ask it before you buy. Ask a specific shop, and get a specific answer.
What breaks, as far as we can tell
Honestly: we do not know, and that is not the same as nothing.
On Okuma we found no spindle-bearing failure evidence, no ballscrew evidence, and no major-component failure evidence at all this pass. What we did find were two official service procedures, which is a different kind of signal. Okuma publishes a thru-spindle coolant pin replacement procedure, which tells you coolant pins are a documented service-wear item on this spindle family. And a tool-changer recovery video from a dealer confirms tool-changer sticking as a documented, recoverable fault on Okuma machines generally. Captions were unavailable on both, so we have the existence of the procedures but not the details or the costs.
On DMG Mori, the two spindle-repair videos we mined are service-shop marketing rather than model-specific teardowns. One does yield something genuinely useful about architecture: most Mori spindles are described as oil-mist lubricated for higher-speed operation, with grease-lubricated variants also in service, and the rebuild shop states it will only use top-name super-precision angular-contact bearings for rebuilds.
That lubrication split is the most actionable thing in this article. Find out which one the specific machine in front of you has. Oil-mist systems are more sensitive to a clean, dry compressed-air supply, and the same failure path shows up on the Haas VF-2 spindle-bearing evidence in our records. If the service history is unclear, go look at the seller's air dryer. A shop that neglected air quality on an oil-mist spindle has been running a slow experiment on your future bearings.
The premium: what we can and cannot say
You want to know whether the premium over a used Haas is worth it. We cannot answer that with evidence, because we do not have comparable failure rates, repair costs, or downtime data for any of these brands. Nobody publishes them. What follows is reasoning, and you should weigh it as such.
The case for paying it is consolidation. A single manufacturer that builds its own control, motors, and drives is a single accountable party when something goes wrong, and if downtime on that machine costs you real money per hour, having one number to call has value that does not appear on the invoice.
The case against is that a small shop buying one machine to add capacity rarely generates enough service events to convert that into savings. And it is worth noting that the alternative is not a transparent parts market either. Haas parts are dealer-quote only, with no public OEM price list, which we verified directly. So the choice is not "priced catalog versus proprietary channel." It is between two quote-driven channels with different depths.
Before you write the check
Because the price data is thin, the verification has to carry the weight.
- Confirm the exact configuration, not just the model. On an NLX, SY versus T versus base is the price. On a GENOS, confirm spindle speed, tool count, and whether the coolant and probing options you are paying for are actually installed.
- Determine the spindle lubrication type on a Mori machine, oil-mist or grease, and inspect the seller's compressed-air setup accordingly.
- Check thru-spindle coolant pin condition and cycle the tool changer repeatedly. Both are documented Okuma service items even though we could not source their cost.
- Call your intended support partner before purchase, not after. Ask whether they service your specific model, what a spindle bearing job typically runs, and what the lead time looks like. Vague answers are data.
- Treat any published price you find on these two brands as a single observation until you have collected several yourself. We have two. That is not enough, and we are telling you so.
The premium is built on something real. Real is not the same as worth it for your shop, and neither of us has the numbers to close that gap yet.
