Okuma CNC Repair Services in Seattle
Control electronics, servo drive and mechanical repair for Okuma machine tools across Seattle — a Pacific-Northwest aerospace, technology and maritime hub, where a mild wet coast replaces the cold of the northern interior.

Repairing Okuma Electronics for Seattle Shops
Seattle is one of the great aerospace centres of the world, home to major commercial-aircraft manufacturing and a deep supplier base, alongside a strong technology sector and a long maritime and shipbuilding tradition on Puget Sound.
An ocean from Germany on the far Pacific side, we primarily support Seattle shops through ship-in repair: you remove and send us the specific faulty board, drive or component, we bench-test and repair it at our German workshop, and ship it back verified working.
For close to twenty years we’ve focused only on Okuma’s OSP control — not the FANUC and Siemens systems most general CNC electronics repairers know. That’s the specialisation Seattle’s aerospace and maritime shops reach for when a local repairer can’t decode an OSP fault.

Common Faults on Seattle-Area Okuma Machines
Encoder & feedback drift
On commercial-aircraft and aerospace work, a failing encoder or scale causes gradual drift that ruins tolerance before it stops the machine — we check feedback accuracy directly rather than assuming a drive fault.
Coastal humidity & corrosion
Damp, salt-tinged Puget Sound air drives gradual connector and contact corrosion — the leading environmental factor on this mild coast rather than cold.
OSP control board faults
Corrupted parameter memory, dying backup batteries and failed power-supply components remain the most common reasons an OSP control won’t boot or throws alarms.
Servo & spindle drive faults
Overcurrent trips and feedback errors present as an axis or spindle that won’t move correctly — we bench-test the drive electronics directly rather than assuming a motor issue.
See our fault analysis and testing & diagnostics services for more on our diagnostic approach.
Industries Running Okuma Equipment Around Seattle
The region’s manufacturing has its own character — here are the sectors we most often support locally.
Aerospace
Precision parts for the region’s commercial-aircraft industry and its supply chain.
Maritime & Shipbuilding
Vessel and marine-engineering components for Puget Sound’s shipyards.
Technology & Electronics
Housings and precision parts for the city’s large technology sector.
Precision Engineering
Short-run and tight-tolerance work for the region’s precision shops.
Metal Fabrication
Structural and general fabrication combined with Okuma machining.
General Machining & Job Shops
Contract shops running Okuma equipment across the Puget Sound region.
Aerospace and a Mild Pacific Coast
Seattle’s commercial-aircraft and aerospace work is precision-critical, so feedback accuracy is everything — a drifting encoder or a marginal drive matters as much as an outright failure, and we look for the drift, not just the dead part.
The Pacific Northwest is mild and wet rather than cold, so the dominant environmental factor here isn’t deep winter but humidity and coastal salt: damp, salt-tinged Puget Sound air drives gradual connector and contact corrosion, a frequent hidden cause of intermittent faults.
Seattle runs North America’s 60Hz supply at 208–240V or 480V three-phase, unlike Germany’s 50Hz/400V, so we confirm a machine’s exact voltage and frequency carefully before any repaired component ships back.
Okuma Machines & OSP Controls We Support
We’re not tied to one machine family: the full Okuma CNC range is supported from your Seattle facility — lathes and turning centers, MULTUS mill-turn, vertical and horizontal machining centers, 5-axis and double-column machines, grinders and older legacy platforms. Start from the Okuma models directory or the list of components we repair.
OSP is where Okuma differs most from other builders — it’s their in-house control, so FANUC or Siemens experience doesn’t transfer cleanly. We repair the whole OSP line, from OSP5000 and OSP700 through the P100–P300 generations to the current OSP-P500. A nameplate photo is enough for us to pin down the exact generation before anything ships.
Shipping a Repair From Seattle to Our German Bench
For Seattle, ship-in is our primary model: send us the specific faulty component, we diagnose and repair it at board level on our German bench, and it travels back verified working. On-site support is available too, especially for machines that can’t easily be moved.
1
Describe the Fault
Machine model, OSP control generation, voltage, alarm codes and a description or photo of what’s happening.
2
We Confirm the Component
We identify exactly what needs to ship, and how to remove it safely, before anything is disconnected.
3
Bench Repair in Germany
Diagnosed and repaired at component level on our workbench, not simply swapped for new.
4
Tested & Returned
Verified under load at your machine’s voltage, then returned by international courier to your Seattle facility, ready to reinstall.
We support Seattle and the wider Puget Sound region — including Everett, Renton, Tacoma and the surrounding aerospace corridor. And we do travel — for machines that can’t easily be moved, or a fault that genuinely needs hands-on diagnosis, we can arrange an on-site engineer visit anywhere in the U.S.; ship-in is simply our primary method given the transatlantic distance. Our emergency & express repair and retrofit & modernization services cover both paths in more detail.

Frequently Asked Questions
Yes — aerospace work needs the tightest, most repeatable accuracy, so we pay particular attention to feedback and drive faults that erode tolerance before they ever stop a machine.
Over time, yes — damp, salt-tinged Puget Sound air corrodes connectors and contacts, a classic source of intermittent faults, so we check for it early on a coastal machine.
It’s exactly why we confirm your machine’s specification carefully. The U.S. runs 60Hz — not Germany’s 50Hz — and industrial voltage is typically 208–240V or 480V, so the exact figures matter here.
Yes — on-site support is available, especially for machines that can’t easily be moved; ship-in is simply our primary method given the transatlantic distance.
