Okuma CNC Repair for Precision Engineering & Tool Making
Independent electronics and mechanical repair for Okuma machines cutting molds, dies and tooling — where geometric accuracy has to hold consistent from the first cavity to the thousandth.

Why Okuma Runs So Deep in Precision Engineering
Okuma’s own history starts with precision: founder Eiichi Okuma built a high-accuracy lathe in-house back in 1898 specifically to machine 0.05mm-wide parts — the technology that eventually turned the company into a machine tool builder in its own right. That heritage shows up directly in the die/mold and tool-making segment today, where Okuma builds heavy, sturdy machines specifically so there are “no shortcuts” in accuracy, whether it’s casting number one off the line or casting number one thousand.
We support the electronics and mechanical side of that consistency. A drifting spindle or a servo fault doesn’t just stop production on a tool and die job — it can quietly degrade cavity finish or geometric accuracy for parts made before anyone notices. Our repair approach is built around catching and fixing that kind of fault at the source, not just clearing the alarm.
Typical Okuma Machines We See in Tool & Mold Shops
Die/mold work tends to demand rigidity, large work envelopes and long unattended runs — which shapes which Okuma platforms show up on the floor.
- MCR & MCV double-column machines — large-part, 5-face mold and die work needing rigidity across a big envelope
- DCMC & GENOS M machining centers — Okuma’s signature precision line, over 10,000 units sold since 1964
- MU-series 5-axis centers — complex tooling geometry cut in fewer setups than 3-axis alternatives

Two Ways We Support Your Shop
Tool and mold shops 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 shops 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 Tool & Mold Machines
Long unattended runs and large, rigid double-column structures create a fault pattern of their own, different from higher-volume production machining.
01
Spindle drift affecting cavity surface finish
A gradually drifting spindle doesn’t throw an alarm — it just slowly degrades the finish or accuracy of a mold cavity, often noticed on inspection rather than on the shop floor.
02
Pallet system faults on unattended long runs
Die/mold work leans heavily on APC and pallet pool systems for hours of unattended machining — a fault here can waste an entire overnight run rather than just pausing it.
03
Double-column axis synchronization issues
Large double-column machines coordinate multiple axes across a big structure — a single drifting servo can throw off geometry across the whole work envelope.
04
Control faults during complex 5-axis toolpaths
Complex mold geometry programmed for 5-axis machining is unforgiving of intermittent control faults — we treat these as high priority given the cost of the material involved.
What We Repair
Component-level repair across the electronics and mechanical systems that keep a tool and mold shop 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 the multi-axis sync faults common on large double-column machines.
Spindle Repair
Bearing, encoder and winding repair for spindles — the first place cavity finish problems usually trace back to.
Pallet & APC Systems
Automatic pallet changer electronics for hours of unattended die/mold production.
Encoders & Feedback Systems
Position feedback repair — what we check first when a large double-column machine’s geometry starts drifting.
Power Supply Units
Regulates voltage across the control cabinet — a common root cause behind intermittent faults.

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 tool and mold makers on their own equipment.
We can diagnose and repair the underlying fault, and our preventive maintenance service can help catch a marginal component before it fails mid-cycle again. Tell us what happened and we’ll help you figure out the cause.
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.
