Okuma Repair Support for Taiwanese Manufacturers
Taiwan is genuinely unusual among the markets we support: it’s not just a customer base for machine tools, it’s one of the world’s own major machine tool producing nations, with Taichung’s dense cluster of machine tool builders and precision component suppliers earning it a reputation as the island’s own machine tool capital. On top of that, Taiwan produces the large majority of the world’s most advanced semiconductor chips, which places extraordinary precision demands on the machining equipment supporting that industry.
We’ve spent close to twenty years focused specifically on Okuma’s OSP control platform — a genuinely different system from the FANUC and Siemens controls that most general CNC electronics repairers in Taiwan are built around. If your OSP control is showing an alarm history nobody locally can decode, or a machine has been sitting idle waiting on a board nobody nearby stocks, that’s precisely the gap our specialization fills.
Taiwan sits a long way from our German workshop, which makes ship-in repair — where you remove the specific faulty component and send it to us for bench-level repair — our clear standard recommendation here, regardless of which part of the island a machine is running in.

Metal Fabrication
General-purpose turning and milling supporting the wider industrial base.
Subtropical, Typhoon-Prone, and Electrically Distinct
Taiwan runs a 110V/220V electrical standard at 60Hz — a different combination from mainland China’s 220V/50Hz system just across the strait, which is worth double-checking rather than assuming based on the wider region. Climatically, Taiwan is subtropical and humid year-round, with a distinct typhoon season that brings intense wind and rain — a combination that can affect facilities differently than the steady tropical humidity we see in, say, Singapore, particularly around sudden pressure and moisture changes during storm events.
Common Faults on Taiwanese Okuma Machines
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 intermittent alarms.
Humidity-related corrosion and condensation faults
Consistent subtropical humidity, intensified during typhoon season, can lead to condensation and corrosion inside poorly sealed cabinets — one of the first things we check on a fault report from the region.
Servo & spindle drive faults
Overcurrent trips and encoder feedback errors typically 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 finish-quality loss point toward bearing wear rather than an electronic fault, particularly on machines producing tight-tolerance semiconductor or precision components.
See our fault analysis and testing & diagnostics services for more on our diagnostic approach.

Components We Repair, and What Each One Does
Knowing what a part actually does makes it easier to describe a fault when you first contact us.
Control Boards
Interprets your program and coordinates every axis, spindle and tool change. We repair component by component rather than defaulting to a full swap.
Servo & Spindle Drives
Amplifiers that turn the control’s low-power signal into the current that drives each motor — a common source of axis faults.
Spindles & Bearing Replacement
Holds and rotates the tool or workpiece. Worn bearings cause noise and vibration; replacement restores accuracy without touching the electronics.
Power Supply Units
Regulates the correct voltages to every board and drive in the cabinet — one of the first places we check on any diagnosis.
Axis & Feed Drives
Positions the tool or table along each axis. A fault shows up as positioning error or an axis that stops responding.
Turrets & ATC Systems
Selects and positions the cutting tool. We repair the motors, sensors and grippers involved.
Encoders & Feedback Devices
Report exactly where an axis or spindle is at every instant. A failing one causes drift that’s easy to mistake for a drive fault.
Operator Panels & Displays
Your window into the control. We repair both modern touchscreens and older CRT-style displays.
The OSP Control Platform
OSP is Okuma’s own control system, not a licensed FANUC or Siemens platform, with its own diagnostic tools and board architecture. We cover the complete range of OSP generations found in Taiwan — legacy floppy-disk-era controls like OSP3000 and OSP5000, the OSP-P100 through P300 generations common on most active machines today, and the current OSP-P500.
How Ship-In Repair Works From Taiwan
The process is the same wherever on the island you’re based.
1
Describe the Fault
Machine model, OSP control generation, alarm codes and a description or photo of what’s happening.
2
We Confirm the Component
We identify exactly what needs to ship, including its voltage rating, 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 & Shipped Back
Verified under load, then shipped back to your facility ready to reinstall.
See our fault analysis and testing & diagnostics services for more on our diagnostic approach.

Frequently Asked Questions
Yes — semiconductor manufacturing equipment is one of the sectors we support regularly in Taiwan, alongside the island’s own machine tool and bicycle manufacturing industries.
Just the specific faulty component in almost every case — a control board, drive unit, encoder or similar. We’ll confirm exactly what’s needed and how to remove it safely before you ship anything.
No — Taiwan runs 110V/220V at 60Hz, while mainland China uses 220V at 50Hz. We always confirm your machine’s exact specification before any repair ships, rather than assuming based on the wider region.
It can — sudden humidity and pressure changes during storm events are worth mentioning alongside the usual model and control-generation details, particularly for condensation-related faults.
Your machine’s model, the OSP control generation (a nameplate or startup-screen photo works well), any alarm codes shown, and a description of the fault — that’s usually enough for a practical first assessment.
