Okuma CNC Parts and OSP Control Spares

If you have an Okuma lathe or machining centre stopped on the shop floor and a board number written on a scrap of paper, you are in the right place. We source Okuma CNC parts and OSP control spares for maintenance teams working against downtime, including obsolete items the OEM channel no longer lists. Send us the number and we will confirm whether it is available new, reconditioned or repairable.

What Are Okuma CNC Parts?

Okuma CNC parts are the electronic and electromechanical components used in Okuma machine tools – CNC lathes, machining centres and turn-mill machines – including OSP control boards, servo and spindle drives, motors, encoders, operator panels, monitors and power supplies. This page covers machine tool spares and OSP control components only, not fishing reels, rods or tackle. Every reference here is to the Okuma machine tool brand and its OSP CNC control.

Okuma designs and manufactures its own CNC control, the OSP platform, rather than fitting a third-party CNC. The control hardware in an Okuma machine is therefore Okuma-specific, and generic CNC spares will not cross-reference. Once a control generation reaches end of life, the parts route changes from OEM supply to independent sourcing and board-level repair.

We are an independent sourcing specialist with 12+ years supplying industrial automation and CNC control parts to maintenance teams. We are not an authorised Okuma distributor. We work through an international network of suppliers and repair centres, which is how we reach obsolete OSP hardware outside the current OEM catalogue.

Okuma Part Types We Supply

We supply Okuma machine tool spares across the control cabinet and the drive train, new, reconditioned or repaired depending on what the part number allows:

• OSP CNC boards and control boards – CPU, memory, axis and I/O cards from the OSP racks
• Servo drives and drive cards – axis amplifiers and individual drive PCBs
• Spindle drives – spindle amplifiers and control cards
• Servo and spindle motors – replacement and reconditioned units
• Encoders and feedback devices – motor-mounted and linear feedback
• Operator panels, CRT monitors and LCD replacements – including LCD upgrades for failed CRT displays
• Power supplies and transformers – control and drive-side supply units
• Keyboards, membranes, cables and connectors – the consumable end of the control

These parts fit Okuma CNC lathes, machining centres, turn-mill machines and Multus-type platforms, as well as machines built under the Okuma Howa name. If your part number is not listed anywhere, still ask: stock moves through the supplier network constantly. We also supply CNC parts for other control platforms if your plant runs mixed equipment.

Okuma OSP Control Systems and Part Types Reference

Match your OSP control generation to the part types we are most often asked for and the realistic support route for each.

Operator note: generation-by-generation stock coverage in this table requires verification before publish.

Legacy OSP support means keeping a control alive after the OEM has declared it end of life: surplus hardware, tested reconditioned units and component-level board repair. It is what keeps a 1990s OSP5000 lathe cutting parts instead of being retrofitted or scrapped.

Obsolete Okuma Control Parts: What to Do When the OEM Says No

Obsolete Okuma control parts are still obtainable through independent supplier networks, used machine breakdowns and board-level repair, even after Okuma has ended OEM support for a control generation. Okuma’s own parts channels serve current-generation machines, so being told a part is discontinued closes the OEM route, not every route.

Three practical options exist: surplus new-old-stock located through the supplier network; a tested reconditioned unit recovered from a decommissioned machine and bench-tested before dispatch; or repair of the board you already have, often the fastest answer on OSP5000 and OSP7000 machines and far cheaper than a full control retrofit.

Current-generation OSP parts usually move quickly, while obsolete items depend on what the network holds and whether a repair is needed. We tell you which situation you are in when we quote, not after you have ordered. We ship worldwide. If your plant also runs Fanuc, Siemens or Mitsubishi controls, our All manufacturers pages cover those platforms.

Okuma Board Repair and Exchange Service

Yes, most Okuma OSP boards, drives and operator panels can be repaired rather than replaced. Once a part number is obsolete, repair is frequently the only option, and it preserves the exact hardware revision your machine was commissioned with.

Repair makes sense when the part number is obsolete, when no reconditioned stock exists, or when the cost of a new assembly is disproportionate to the machine’s remaining service life. Replacement makes sense when the part is still current, when you want a spare on the shelf, or when a machine on critical production cannot wait for a bench turnaround.

Repairs are fixed price and quoted before work starts, with a no fix no fee policy: if the unit cannot be repaired, you do not pay the repair charge. Every part carries a 12-month warranty, new or reconditioned, and repaired units are covered on the same basis. Repair is coordinated through our partner repair-centre network, not delivered as an authorised Okuma service. Our Repairs and exchange service covers boards, drives, motors and panel hardware.

How to Identify Your Okuma Control Part Number

Okuma control part numbers are printed on the board itself, usually as a hyphenated code such as 1911-xxxx or E4809-xxx-xxx-xx, and can be cross-checked against the machine’s parts book and the control cabinet layout drawing. The PCB silkscreen and the adhesive label are the first two places to look.

Also check drive nameplates, the inside of the control cabinet door, the parts book and the OSP maintenance screens. When you enquire, send us:

• The part number, as printed, including any suffix
• Machine model and OSP control generation
• Machine serial number
• A clear photo of the board label and, if possible, the whole card

Photos are usually enough when a label is scorched, because most OSP cards can be identified from the layout and silkscreen. The serial number matters because two machines of the same model can carry different control revisions and incompatible cards. Contact us for a quote and we will confirm the correct number before anything ships.

Why Maintenance Teams Use Us for Okuma CNC Parts

We have spent 12+ years sourcing industrial automation and CNC control parts, and our international network of suppliers and repair centres reaches obsolete OSP hardware outside the OEM channel. Every part carries a 12-month warranty, repairs are fixed price with no fix no fee, and a dedicated account manager handles your enquiry from quote to delivery with worldwide shipping. We are an independent sourcing specialist, not an authorised Okuma distributor, which is precisely why we can help when the authorised route has run out. Operator note: any published lead-time or stock-volume figures require verification.

Okuma CNC Parts FAQs

What is Okuma OSP?

OSP is Okuma’s in-house CNC control platform, fitted across its lathes, machining centres and turn-mill machines. Generations include the OSP-U10 and U100 family, OSP5000 and OSP5020, OSP7000 and OSP7000L, and the current OSP-P200, OSP-P300 and OSP-P500 controls. Because OSP is proprietary, its boards and drives are Okuma-specific.

Can you repair an Okuma OSP board?

Yes. Most OSP control boards, servo and spindle drive cards, power supplies and operator panels are repairable at component level. Repairs are quoted at a fixed price with no fix no fee, coordinated through our partner repair-centre network, and covered by a 12-month warranty.

Where can you buy obsolete Okuma CNC parts?

Obsolete Okuma CNC parts come from independent sourcing specialists rather than the OEM catalogue. We locate them through surplus stock, decommissioned machines and board repair, drawing on an international supplier and repair-centre network.

How do I identify an Okuma control part number?

Read the number from the board label or silkscreen, then confirm it against the machine parts book and cabinet layout drawing. If the label is damaged, send a photo with the machine model, control generation and serial number and we will identify it for you.

Does Okuma use Fanuc controls?

Okuma machines run the in-house OSP control rather than Fanuc. Some machines built under licence, and certain Okuma Howa models, may carry different hardware, which is why we confirm the control generation and serial number before quoting a part.

Send us your Okuma part number and get a quote while your machine is still in setup. Give us the part number, machine model and OSP control generation, or just a photo of the board label, and a dedicated account manager will confirm availability, price and lead time on the Okuma CNC parts you need. New, reconditioned or repaired, every part carries a 12-month warranty. From supply to repair of your machines, we are here to help.
