Used Okuma Machines We Buy

Who Makes Okuma Machines

Okuma machines are built by Okuma Corporation in Japan. Its history starts in 1898, when the inventor Eiichi Okuma set up the Okuma Noodle Machine Co. to make and sell noodle-making machines; machine tool production began in 1904, and by 1937 Okuma says its machine tool output was the largest in Japan by value. The company has been called Okuma Corporation since 1991.

In 2006 four companies merged into today's Okuma: Okuma Holdings, Okuma, Okuma & Howa and Okuma Engineering. Okuma & Howa was one of the four, so a lathe with an Okuma-Howa plate belongs to the same family, and we buy it as an Okuma.

Where Okuma Builds Its Machines

Okuma builds and assembles in its Dream Site factories in Japan. Dream Site 1 began operation at the World Headquarters Plant in 2013, producing multitasking machines, medium and large lathes and vertical lathes. Dream Site 2 makes small and medium lathes and grinders, with its machine shop running from 2017, and Dream Site 3 opened at the Kani Plant in 2019.

Outside Japan, Okuma set up Okuma Machine Tools Inc. as a US manufacturing company in 1987 and Okuma America Corporation in 1995, and BYJC-OKUMA in Beijing was set up for manufacturing in 2002.

OSP: The Control Okuma Builds Itself

Okuma designs its own CNC rather than buying one. It developed the OSP III in 1963 with an absolute position feedback encoder, and Okuma says that made it Japan's only comprehensive maker of both machine and control. It still develops all its NC components in-house, from the controller to the motors, servo drive units and encoders.

For a seller, the OSP generation works like a date stamp. An OSP5000 screen points to an older machine, the PC-based OSP-P100 and OSP-P200 came in the 2000s, and the OSP-P300 and newer belong to the current era. The table below gives Okuma's own dates.

Okuma OSP Generations

The OSP controls on Okuma's own development history, which runs to 2022, with the year each arrived:

Years are from Okuma Corporation's OSP history page. Okuma Europe's company history gives 2014 for the OSP suite launch and 2023 for the OSP-P500.

Okuma's Current Lines

Okuma's catalog splits into lathes, multitasking machines, machining centers, double-column machines and grinders. On the turning side are the LB EX and SPACE TURN one-saddle lathes, GENOS L lathes, TWIN STAR twin-spindle and SIMUL TURN two-saddle machines, 2SP parallel-spindle lathes and V-series vertical lathes. Multitasking runs through the MULTUS U and B series and the VTM vertical multitasking machines.

For milling there are the MB vertical and MA horizontal machining centers, the MU-V 5-axis verticals such as the MU-6300V, and the large MILLAC 5-axis machines. Older families such as Crown, Captain and Cadet no longer appear in Okuma's current lineup, but we buy them too.

Okuma Distributor Support Versus a Direct Sale

Okuma's own sites send owners to a local distributor for sales and service, with spare parts and customer care alongside. Okuma describes its approach as total responsibility, from design through machining and maintenance. If the Okuma is staying in production, your distributor is the call. If it is leaving the building, we buy it directly, and a distributor service record helps us confirm its condition sooner.

OSP Control Generation Drives the Okuma Number

Okuma builds its own OSP control, and which generation is on the machine, the OSP-P300 or the newer OSP-P500 versus the older OSP-700 series still found on Crown and Captain lathes, is one of the first things that sets the offer. Swing, spindle bore, and chuck size matter most on the lathe side, since Crown, Captain, Cadet, and LB-series machines make up the core of our used Okuma lathe inventory. Spindle taper condition and bar capacity round out the picture for bar-fed models.

Mill-Turn and Machining Centers Get Evaluated Differently

MULTUS mill-turn machines and GENOS or MC-series vertical machining centers are priced on axis travel, spindle motor power, and whether a live-tooling turret or second spindle is fitted, the same criteria we would apply to any current-generation machining center regardless of brand.

Documentation That Speeds Up an Offer

Serial number, OSP control version, spindle hours if the control logs them, and chuck or tooling included. Older Crown and Captain lathes especially benefit from a recent calibration record, since they're no longer in current production.

Full Line of Okuma Lathes, Mill-Turn, and Machining Centers

Beyond Crown, Captain, and current LB and GENOS lathes, we buy Okuma's 2SP-V40 and 2SP-V60 parallel-spindle turning centers, along with the Cadet line that predates the current LB series. On the mill-turn side that includes the full MULTUS B series from the B200 up, and the MULTUS U line, both scoped on turret condition and axis travel the same way regardless of which series it is. GENOS M460-V and M560-V verticals, the MB-V line, and MU-V 5-axis machines fill out our vertical machining center coverage, alongside MA-400HA, MA-600HB, and MB-H horizontal machining centers. A machine doesn't need to carry a current model name to get a real offer, an older MC-series center running a legacy OSP screen is still evaluated on the same spindle and travel basics as a current GENOS. OSP control software version matters as much as the hardware generation, two machines running the same P300 hardware can carry different software builds, and a more current build is generally easier for a shop to integrate with modern CAM software, which factors into how the machine is perceived by the next buyer. The parallel-spindle layout on the 2SP-V line also opens up complete parts in one setup, a meaningful capability difference from a standard single-spindle LB, and we account for that when the option is installed and functioning correctly.

Okuma's Reputation for Longevity Works in Your Favor

Okuma has a reputation for durability that outlasts most CNC brands, and a well-maintained machine, even an older Crown or Captain lathe no longer in production, still holds real interest from buyers. That reputation shapes how we look at a machine, particularly one with a documented service history. It does not mean every Okuma commands the same number, spindle condition and OSP generation still matter, but the brand's staying power gives an older lathe a longer useful life than most competing makes. That's part of why we ask for a recent calibration record on anything built before OSP-P300, it's usually the single best proof that a machine still cuts to tolerance despite its age, and it tends to matter more for an Okuma than for a brand where shops replace machines on a shorter cycle. Shops that specifically hunt for an older Okuma over a newer competing brand tend to already know how to maintain OSP controls and Okuma's mechanical platform, which is part of why a well-kept older machine finds a buyer faster than the same condition machine in an unfamiliar brand would.

Crown and Captain Lathes Have Their Own Rules

Crown and Captain lathes, including the 762S and 769S variants, are no longer in current production, which changes how we scope them compared to a current LB or GENOS. Swing, spindle bore, and chuck size still set the ceiling, but since parts for older generations can be harder to source than for current models, a documented service history and confirmation that critical wear parts are still sourceable matter more than they would on a newer lathe. That doesn't mean these older lathes are worth less, plenty of shops specifically look for a Crown or Captain because it's a known, reliable machine at a lower entry point than a current model, and that demand keeps a well-kept older Okuma lathe genuinely worth a call. The same logic extends to older Okuma machining centers built before the GENOS name existed, an MA or MC-series center from that era gets scoped the same way, spindle condition and confirmed part sourcing carrying more weight than how recently the model name was current. None of this changes the basics we ask for, serial number, control version, and a recent calibration record if you have one, but it does change how we weigh what we're looking at once we have those details.
