When the Machine Goes Down, the Entire Schedule Shifts
A machine tool failure affects more than one operation. Production schedules slip, operators lose time and downstream work begins backing up. NNG evaluates the machine, operating symptoms and related mechanical systems to help identify a practical path back to production.

Machine Tool Repair & Rebuild Services
NNG provides diagnostics, mechanical repair, rebuilding and component support for machining centers, turning centers, grinders, milling machines and other industrial production equipment. Machine failures are not always isolated to the first damaged part. Wear, alignment problems, drive-system issues and related component damage can all affect accuracy, reliability and production performance. NNG evaluates the machine and affected systems before recommending repair, rebuilding, component replacement or another service path.
Diagnostics & Troubleshooting
Evaluation of operating symptoms, mechanical conditions, alarm information and suspected failure points.
Mechanical Repair & Component Replacement
Repair and replacement support for worn, damaged or failed machine components and assemblies.
Alignment & Calibration
Inspection and correction support for machine alignment, geometry, positioning and operating accuracy.
Gearbox & Drive-System Support
Inspection, repair and replacement support for gearboxes, couplings and related mechanical drive components.
Component Removal & Installation
Coordination and field support for removing, replacing and reinstalling qualifying machine components.
Preventive Maintenance & Service Planning
Inspection and maintenance support designed to identify wear, reduce avoidable failures and support more predictable machine performance.
Assess → Diagnose → Approve → Repair or Rebuild → Verify → Return to Production
Repair Decisions Based on the Complete Machine
A machine problem may begin with one failed component, but its effects can spread through the spindle, gearbox, workholding, alignment and motion systems. NNG evaluates the machine and the relationship between its mechanical systems so the recommendation addresses the actual condition of the equipment rather than only the first visible symptom.
Find the source of the problem before replacing the wrong part. Repair support built around accuracy, production and uptime.

The Right Path...
The right option depends on the machine’s condition, repair history, replacement availability, production requirements and long-term operating needs.
Repair
Correct the identified failure when the affected components and surrounding systems remain suitable for continued service.
Rebuild
Restore broader mechanical systems when wear, damage or performance loss calls for a more comprehensive service scope.
Replace
MACHINE TOOL SERVICE QUESTIONS
What Customers Need to Know
What information should I provide?
Send the machine manufacturer and model, serial number, symptoms, alarm information, photos, maintenance history, service location and required timing.
What machine tools does NNG service?
NNG may support CNC lathes, turning centers, machining centers, milling machines, grinders and other production equipment depending on the manufacturer and required work.
Does NNG provide on-site service?
On-site evaluation, component removal, installation and related support may be available depending on the machine, location and service scope.
Can NNG support obsolete machines?
Support may be possible when technical information, repairable components, dimensional data or qualified replacement options remain available.
What is the difference between repair and rebuilding?
Repair typically addresses an identified failure or localized damage. Rebuilding involves a broader restoration of worn mechanical systems and related components.
Can NNG rebuild an entire machine?
Complete or partial rebuilding may be evaluated case by case based on the machine, condition, documentation, required accuracy and project scope.
Does NNG provide preventive maintenance?
Preventive-maintenance support may be available for qualifying machines and locations.
What testing is performed after service?
Verification depends on the approved scope and may include mechanical checks, alignment review, dimensional inspection and functional testing.
Need Machine Tool Repair or Rebuild Support?
Send the machine information, symptoms, photos, service location and required timing. NNG will review the request and help identify the most practical repair, rebuilding or replacement path.
