Comprehensive Okuma Spindle Repair and Maintenance

Our team’s technical expertise spans the full spectrum of Okuma machine tool technologies. We service Okuma-specific components and systems, including:

VAC integral motor spindles: We restore the direct-drive motorized spindles found in LB Series turning centers and MU Series multitasking machines, including rewind services for integrated stator windings.
OSP control integration: Our technicians precisely calibrate the feedback sensors that communicate with Okuma’s OSP-P300, OSP-E100, and OSP-7000 control systems to ensure real-time accuracy.
High-frequency grinding spindles: We rebuild grinding heads to factory specifications, ensuring they can operate reliably at elevated speeds for critical surface finishing.
Heavy-duty turning spindles: We handle robust spindle assemblies for Okuma LB, LU, and LOC Series lathes, restoring the rigidity needed for large-diameter workpieces.
5-axis milling spindles: Our team services complex spindle units for MA, MB, and MU Series machining centers, maintaining strict geometric tolerances for multi-axis positioning.

Setco’s Spindle Restoration Process

Setco’s rigorous spindle rebuilding and repair services follow a proven methodology designed to restore performance:

We perform vibration analysis and electrical testing of stator windings before disassembly to identify failure modes accurately.

Technicians carefully dismantle the spindle, logging every component and wear pattern to ensure a precise reassembly in our facility or on your floor.

We measure critical dimensions against original Okuma specifications to determine the exact scope of work.

Our team provides a detailed, no-obligation quote outlining the necessary repairs and costs up front for full transparency before work begins.

We restore worn housing bores and shaft journals to original geometric tolerances (GDT) through advanced chrome plating and grinding techniques.

Rotating components are balanced to ISO 1940-1 G0.4 standards for secure, vibration-free operation at maximum spindle speeds.

We conduct closed-loop run-off testing until the spindle reaches thermal stability to verify performance under actual load conditions.
