Okuma Repair Support for Tainan Manufacturers
Tainan is a rising industrial power in the south — home to the Southern Taiwan Science Park and its major semiconductor fabrication, a fast-growing green- and solar-energy sector, and a strong base of steel, metals and precision machinery in Taiwan’s oldest city.
Taiwan sits a long way from our German workshop, so ship-in repair is our clear standard recommendation for a Tainan job: remove the specific faulty component, send it to us through Taoyuan’s air-cargo links, and we bench-repair it and return it tested and ready to refit.
Okuma’s OSP control has been our single focus for close to two decades — a different platform from the FANUC and Mitsubishi systems most Taiwanese repairers are built around, so a stubborn OSP fault is exactly what we’re set up for.

Industries We Support Around Tainan
The region’s manufacturing has its own character — here are the sectors we most often support locally.
Semiconductors & Electronics
Ultra-precision parts for the Southern Taiwan Science Park’s chip-fabrication base.
Green & Solar Energy
Component work for the south’s fast-growing solar- and renewable-energy sector.
Steel & Metals
Machining for the region’s steel and metals operations.
Precision Engineering
Tight-tolerance and prototype work for the high-tech supply chain.
Metal Fabrication
Structural and general fabrication combined with Okuma machining.
General Machining & Job Shops
Contract shops running Okuma equipment across the south.
Semiconductors and Green Energy in the South
Tainan’s semiconductor work is precision-critical, where feedback accuracy is everything — so on chip-related and high-tech machining a drifting encoder or a marginal drive quietly erodes accuracy long before it stops the machine, and feedback and positioning faults get particular attention.
The sunny, hot south is Taiwan’s green-energy heartland, with large-scale solar behind much of the island’s renewable capacity — but the climate is still humid and typhoon-exposed, so heat, moisture and storm-season power surges are all factors we weigh on a southern fault report.
The electrical point is consistent across the island: Taiwan runs 110V/220V at 60Hz, aligned with the American and Japanese standard rather than Europe’s 50Hz, so we confirm exact voltage and frequency before a repaired component ships back.
Common Faults on Tainan Okuma Machines
Encoder & feedback drift
On semiconductor 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.
Heat, humidity & corrosion
The hot, humid south drives condensation and connector corrosion in unsealed cabinets — an intermittent-fault suspect we check for here.
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.
Okuma Machines & OSP Controls We Support
We’re not tied to one machine family: the full Okuma CNC range is supported from your Tainan 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 Mitsubishi 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.
How Ship-In Repair Works From Tainan
Taiwan sits a long way from our German workshop, so ship-in is our clear standard recommendation for a Tainan repair: remove the specific faulty component, send it to us through Taoyuan’s air-cargo links, and we bench-repair it and return it tested and ready to refit.
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 & Flown Back
Verified under load at your machine’s voltage, then returned by international air-cargo through Taoyuan to your Tainan facility, ready to reinstall.
We support Tainan and the surrounding region — including the Southern Taiwan Science Park, Yongkang, Rende and the southern coast. And we do travel — for a fault that genuinely needs hands-on diagnosis we can arrange an on-site engineer visit anywhere in Taiwan; ship-in is simply the standard given the distance. Our emergency & express repair and retrofit & modernization services cover both 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.
It’s exactly why we confirm your machine’s specification carefully. Taiwan runs 60Hz — not Germany’s 50Hz — and voltage is 110V/220V, so the exact figures matter here.
Yes — you send only the specific faulty component, and Taoyuan’s air-cargo links to Europe are fast, so courier turnaround plus bench repair is usually measured in days. We confirm what to send first.
Yes — for a fault that genuinely needs hands-on diagnosis we can arrange an on-site visit; ship-in is simply the standard given Taiwan’s distance.
