CNC Ballscrew & Ball Screw Repair Services

A failed or worn ballscrew can affect far more than machine movement. Positioning errors increase, repeatability suffers, finished parts fall outside tolerance and production becomes less predictable. NNG Industries provides CNC ballscrew and ball screw inspection, repair, rebuilding, exchange and replacement support for machine tools and industrial linear-motion systems. The goal is not simply to replace balls or adjust the nut. NNG evaluates backlash, wear, straightness, journals, raceways and related operating conditions so the recommended service path reflects the condition of the assembly and the performance requirements of the machine.

Backlash Evaluation

Inspection and measurement to identify excessive play, lost motion and positioning issues.

Nut Rebuilding

Disassembly, inspection and rebuilding of single-nut and double-nut ballscrew assemblies.

Journal Repair & Machining

Inspection, machining and repair of damaged or worn journals and related surfaces.

Precision Machining & Grinding

Machining and grinding services based on the spindle condition and approved repair scope.

Straightness & Raceway Inspection

Evaluation of screw straightness, threads, raceways, seals and other critical components.

Exchange & Replacement Options

Exchange-unit evaluation and replacement sourcing when repair is not the most practical option.

Intake → Inspect → Diagnose → Approve → Repair → Test
Why NNG
Technical Support Built Around Precision

When a ballscrew begins losing accuracy, the visible symptom may not reveal the full problem. NNG evaluates the assembly, machine requirements and available repair options so customers can make a more informed decision about how to restore motion and positioning performance.

ONE FAILURE. THREE POSSIBLE PATHS.

The Right Path...

Depends on the spindle’s condition, repair history, replacement availability and production requirements.

Repair or rebuild

Restore the existing ballscrew when its condition and repair economics support continued service.

Exchange

Reduce waiting time when a compatible exchange assembly is available.

Replacement
Source a new, rebuilt, used, OEM or qualified aftermarket assembly when repair is not practical.
 

BALLSCREW REPAIR QUESTIONS

What Customers Need to Know

Answers to common questions about inspection, exchange availability, obsolete assemblies and what to send with a service request.
What information should I provide?

Send the machine manufacturer and model, ballscrew information, dimensions, serial number, symptoms, photos, repair history and required timing. A clear photo of the machine and component nameplates is especially helpful. Additional details can be uploaded through the service request form.

Exchange availability depends on the machine, ballscrew dimensions, configuration and current inventory.

Support may be possible when drawings, dimensions, repairable components or suitable replacement options remain available.

Depending on the available drawings, measurements and application requirements, NNG may repair the original assembly or assist with an appropriate replacement solution.

Turnaround depends on the assembly condition, extent of damage, machining requirements, parts availability and approval timing.

Testing may include backlash measurement, preload evaluation, straightness inspection, dimensional verification, smooth-travel inspection and functional testing appropriate to the completed work.
