Okuma CNC Repair for Marine & Shipbuilding Manufacturing
Independent electronics and mechanical repair for Okuma machines cutting propellers, shafts and structural marine components — large parts, contoured geometry, and no room for a machine to be down.

Why Okuma Runs So Deep in Marine Manufacturing
Marine components present a genuinely specific machining challenge: contoured, large-format parts like propellers that are difficult even to fixture reliably, let alone cut to the tolerances that keep a vessel running efficiently. One real example we’ve seen documented involved a shop building an automated machining cell specifically for contoured marine propellers, where fixturing turned out to be the single biggest hurdle — solved on an Okuma GENOS M660-V vertical machining center, chosen for its large work table, compact footprint and CAT 40 Big-Plus spindle built for exactly this kind of large, complex part.
We support the electronics and mechanical side of that capability. A control or servo fault on a machine cutting a propeller blade or a large propulsion shaft isn’t a quick fix elsewhere — these parts and the machines that cut them represent serious capital, and downtime compounds fast. Our repair approach is built around getting a clear, fast diagnosis before more time is lost.
Typical Okuma Machines We See in Marine Manufacturing
Large, contoured parts and heavy shafting both show up in marine work, which shapes which Okuma platforms are on the floor.
- GENOS M660-V & similar machining centers — contoured propellers and complex large-format marine components
- Large-format LB lathes — propeller shafts and other heavy turned components
- MCR double-column machines — large structural hull and engine mounting components

Two Ways We Support Your Facility
Marine manufacturers don’t all need the same thing from us, so we offer two genuinely different paths depending on what’s down and how urgent it is.
On-site repair. For faults that need hands on the machine — wiring, mechanical work, on-machine diagnostics — we send a technician to your facility. Our country coverage above reflects where we’ve built up this kind of on-site delivery experience.
Mail-in component repair. For a specific failed board, drive or spindle, many plants find it faster to ship us the component directly rather than wait for a site visit. We diagnose and repair it at component level in our workshop, then ship it back tested and ready to reinstall.
Common Faults We See on Marine Manufacturing Machines
Large, contoured parts and heavy shafting create a fault pattern of their own, different from smaller general-purpose equipment.
01
Surface finish issues on contoured propeller blades
A gradually wearing spindle doesn’t necessarily throw an alarm — it just slowly degrades blade finish, which affects vessel efficiency and vibration long-term.
02
Feedback drift on complex contoured geometry
Propeller and hull component geometry is unforgiving — a drifting encoder shows up in the finished part before it shows up as an alarm.
03
Servo faults on heavy shaft turning
Large propeller shafts put sustained load on axis and spindle drives — a different stress profile than typical small-part turning.
04
Fixturing-related sensor and interlock faults
Contoured marine parts are notoriously difficult to fixture reliably — sensor and interlock faults tied to custom fixturing setups are a common source of nuisance stops.
What We Repair
Component-level repair across the electronics and mechanical systems that keep marine manufacturing running.
OSP Control Boards
Board-level repair across every OSP generation, from legacy floppy-disk controls to current OSP-P500.
Servo Drive Units
Axis and spindle drive repair, including faults from sustained load on heavy shaft turning.
Spindle Repair
Bearing, encoder and winding repair for spindles cutting contoured propeller and hull geometry.
Encoders & Feedback Systems
Position feedback repair — the first place we look when contoured part geometry starts drifting.
Power Supply Units
Regulates voltage across the control cabinet — a common root cause behind intermittent faults.
Pallet & APC Systems
Automatic pallet changer electronics for large marine component handling and unattended runs.

Frequently Asked Questions
No. We are an independent repair company, not an authorized Okuma dealer, distributor or service partner. We repair Okuma CNC electronics and mechanical systems for marine and shipbuilding manufacturers on their own equipment.
Tell us the symptom and machine model and we’ll give you a realistic timeline based on whether it needs an on-site visit or can be handled as a mail-in component repair — we understand what an interrupted cycle costs on large, expensive marine components.
Yes — mail-in component repair is one of our two core service paths, and for a specific known-faulty part, it’s often faster than scheduling a technician visit. We diagnose and repair it at component level, then ship it back tested.
Yes — we repair every OSP control generation, from legacy floppy-disk-era controls through the current OSP-P500. See our OSP controls pages for details on your specific generation.
Quite possibly, yes — the countries listed reflect where we have established on-site delivery experience, not the limit of where we work. Mail-in component repair, in particular, isn’t limited by location. Contact us with your details and we’ll confirm.
