Okuma Repair Support for Derby Manufacturers
Few cities anywhere pack as much high-precision manufacturing into one place as Derby. It’s a global centre for aero-engine production, a major rail and rolling-stock manufacturing base, and home to large-scale automotive assembly — three demanding industries whose tolerances leave no room for a marginal machine.
We handle a Derby repair two ways: ship-in, where you send the specific faulty component to our German bench, or an on-site engineer visit for a larger installation. Since the UK left the EU there are customs formalities on parts crossing to Germany and back, which we handle as routine, so ship-in stays simple.
Okuma’s OSP control is all we do, and has been for close to twenty years — a genuinely different system from the FANUC and Siemens controls most UK repairers are set up for, and the reason customers reach past their local service company to us.

Precision parts for Derby’s world-leading aero-engine and aerospace industry.
Rail & Rolling Stock
Components for the city’s major rail and rolling-stock manufacturing base.
Automotive Manufacturing
Machining for the region’s large-scale automotive assembly and suppliers.
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 Derby region.
Common Okuma Faults We Diagnose in Derby
Encoder & feedback drift
On aero-engine and precision 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.
OSP control board faults
Corrupted parameter memory, dying backup batteries and failed power-supply components are the most common reasons an OSP control won’t boot or throws intermittent alarms.
Servo & spindle drive faults
Overcurrent trips and encoder 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.
Spindle bearing wear
Noise, vibration and a drop in finish quality point to bearing wear rather than an electronic fault, particularly on hard-worked precision machines.
See our fault analysis and testing & diagnostics services for more on our diagnostic approach.
Aero Engines, Trains and Cars in One City
Derby’s three great industries — aero-engines, rail and automotive — all live or die on precision, and that shapes how we read a fault here. On aero-engine and high-value components especially, a drifting encoder or a marginally out-of-tune drive quietly erodes accuracy long before it stops the machine, so we look for the drift, not just the dead part.
It’s precision-critical work with unforgiving tolerances, so feedback and positioning faults sit at the top of our list, alongside the usual control questions.
The UK’s damp maritime climate is mild on electronics, with humidity the main environmental factor rather than salt or hard cold. Power is 230V/400V at 50Hz — Europe’s frequency — so a repaired component returns without adaptation.
Okuma Machines & OSP Controls We Support
Whatever sits on your Derby shop floor, we cover the full Okuma catalogue — turning centers, MULTUS mill-turn platforms, vertical and horizontal machining centers, 5-axis, double-column machines and grinders, right back to legacy models. Browse the complete Okuma models directory, or jump straight to every component we repair for detail on a specific board, drive or assembly.
On the control side, OSP is Okuma’s own platform — not a re-badged FANUC or Siemens system — with its own diagnostics and board architecture. We cover every OSP generation: the floppy-era OSP5000, the OSP-P100 through P300 controls on most machines in service today, and the current OSP-P500. Send a photo of the control-cabinet nameplate and we’ll confirm the generation before anything ships.
How We Handle a Derby Repair
A Derby repair can go two ways — on-site or ship-in. Since the UK left the EU there are customs formalities on parts crossing to Germany and back, which we handle as a matter of routine, so shipping a board in for repair stays straightforward.
1
Describe the Fault
Machine model, OSP control generation, alarm codes and a description or photo of what’s happening.
2
On-Site or Ship-In
We agree the right route — an engineer visit for a larger installation, or removing the faulty component to send in.
3
Bench Repair in Germany
Diagnosed and repaired at component level on our workbench, not simply swapped for new.
4
Tested & Back in Service
Verified under load, then shipped back or refitted on-site at your Derby facility, ready to run.
We support Derby and the surrounding region — including Burton upon Trent, Nottingham and the wider East Midlands. As the UK is now outside the EU, parts crossing to our German workshop pass through customs — we handle the paperwork so ship-in stays simple. Our emergency & express repair and retrofit & modernization services cover both the on-site and ship-in paths in more detail.

Frequently Asked Questions
Yes — that 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.
Yes — since the UK left the EU there are customs formalities on parts crossing to our workshop and back. We handle the paperwork as routine, so ship-in stays straightforward.
Just the specific faulty component in almost every case. We’ll confirm what to send and how to remove it safely first.
Yes — 230V/400V at 50Hz shares continental Europe’s frequency, so no adaptation is needed. We still confirm your machine’s exact specification before any repair ships.
Your machine’s model, the OSP control generation, any alarm codes shown, and a short description of the fault.
