What ARMROID Is
ARMROID is Okuma’s built-in robot system — a four-axis robotic arm packaged directly inside the machine tool itself, rather than bolted on as a separate cell. It was the first system of its kind, integrated inside CNC lathes and mill-turn centers rather than standing beside them, which saves floor space and removes the cost and complexity of hiring a third-party systems integrator.
The robot and the machine share a single OSP operation panel. An operator sets start and end coordinates through Okuma’s ROID Navi software, and the system automatically generates a collision-free motion path — no separate robot programming knowledge required. A built-in Collision Avoidance System keeps the robot and machine tool aware of each other’s position at all times, and the arm can also be jogged manually using the machine’s pulse handle for precise positioning.
We support the control electronics behind this system — repair, plus setup, reconfiguration and optimization for machines that already have ARMROID installed. Because ARMROID is built into the machine tool at the factory for a specific set of models, it isn’t something we retrofit onto an older machine that wasn’t originally equipped with it. Where we add value is afterward: recommissioning the robot after a machine move, reconfiguring end effector setups, tuning ROID Navi programs, and diagnosing and repairing faults at component level. We are an independent service provider, not an authorized Okuma dealer or service partner — see our testing & diagnostics and control repair services for how we approach OSP-integrated automation work.
4-Axis
J1–J4 robotic arm control
5–10kg
Max payload, depending on machine variant
±0.05mm
Repeatability precision
572–1,440mm
Max working range, by configuration
End Effector Options
ARMROID can carry up to three end effectors on board at once, automatically exchanging between them mid-cycle. Each has its own drive and sensor electronics that we diagnose and repair individually.
Workpiece Hand (Parallel)
Parallel-jaw gripper for loading and unloading flange-type or block workpieces.
Workpiece Hand (3-Jaw)
3-jaw gripper for holding shaft-type billets around their end faces, up to 10kg.
Support Rollers
Rollers that steady a shaft-type part during turning to suppress chatter.
Coolant/Air Blast Nozzle
Nozzle that clears the cutting zone of chips and swarf during and after machining.

What We Repair on ARMROID
Because the robot shares its control system with the machine tool, most ARMROID faults trace back to a specific board, drive or sensor rather than the arm itself. Here’s what we work on.
Robot Control Interface Boards
The boards that let the OSP control coordinate robot motion alongside the machine’s own axes. Faults here typically show up as the robot failing to respond, or motion commands not executing.
Joint Servo Drives
Amplifiers that drive each of the arm’s four joints (J1–J4). A single failed drive typically shows up as one joint losing position or refusing to move.
Joint Encoders & Feedback
Report each joint’s exact position back to the control. A failing encoder causes drift that’s easy to mistake for mechanical wear.
ROID Navi Interface & Display
The shared operation panel that programs both machine and robot. We repair the display and interface boards behind it.
Collision Avoidance Sensors
Sensors that keep the robot and machine tool aware of each other’s position. A fault here can trigger false stops or, if ignored, real collisions.
Power Supply Units
Regulates voltage to the robot’s control and drive electronics — one of the first things we check on any fault.
Common ARMROID Faults
One joint loses position or won’t move
Usually a single joint’s servo drive or encoder rather than the whole arm — we test each joint’s drive electronics individually before recommending a repair.
Robot stops or won’t run in automatic mode
Often traced to the collision avoidance system or a communication fault between the robot control interface and the OSP, rather than a mechanical jam.
ROID Navi interface unresponsive or frozen
Display and interface board faults are common on units that have been running for years — usually repairable at board level.
End effector exchange failures
Usually a sensor or drive fault at the exchange station rather than a problem with the effector itself — we test each independently.
See our fault analysis service for more on how we approach an ARMROID diagnosis.
Compatible Okuma Machines
ARMROID is available on a specific set of Okuma turning and machining platforms, in a turning configuration and a milling configuration.
How ARMROID Repair & Setup Support Works
For a specific faulty board or drive, ship-in repair is almost always the fastest path. For setup, recommissioning or reconfiguration work, we typically start with a remote consultation to scope what’s needed before any on-site visit.
1
Describe the Fault
Which joint or function is affected, any alarm codes, and your OSP control generation.
2
We Confirm the Component
We identify exactly which board, drive or sensor needs to ship for bench-level repair.
3
Bench Repair in Germany
Diagnosed and repaired at component level, not simply swapped for a new assembly.
4
Tested & Shipped Back
Verified under load before it goes back to you, ready to reinstall.
Frequently Asked Questions
No. We are an independent repair company, not an authorized Okuma dealer, distributor or service partner. We specialize in component-level repair of the control electronics behind Okuma systems, including ARMROID.
No — ARMROID is built into the machine tool casting at the factory for a specific set of models, so it can’t be retrofitted onto a machine that wasn’t originally built with it. If your machine already has ARMROID, we can help with setup, reconfiguration and repair. If you’re looking to add automation to a machine that doesn’t have it, our STANDROID, bar feeder and pallet changer pages cover genuinely retrofittable options.
Our focus is the control electronics, servo drives, sensors and interface boards — the parts of an ARMROID fault that are almost always the root cause of a robot that’s stopped working. We don’t perform mechanical arm repairs.
Often, yes. Describe the symptom — which joint, what alarm code, whether it happens in automatic or manual mode — and we can usually narrow it down before you disconnect anything.
Yes — the robot control interface boards differ between OSP generations, so knowing which control your machine runs helps us identify the correct part before anything ships.
ARMROID Down, Or Needs Reconfiguring?
Tell us what’s happening — a fault, a machine move, or a setup that needs tuning — and we’ll help you figure out the right next step.
