Live Tooling Repair, Sales & Exchange Services
Live tooling allows CNC turning centers to perform milling, drilling, tapping and other driven operations without moving the part to another machine.
When the unit develops excessive runout, noise, heat, leakage, vibration or loss of torque, machining accuracy and production efficiency can suffer quickly.
NNG Industries provides inspection, repair, rebuilding, sales, exchange and replacement support for live tooling units used across CNC lathes and turning centers. The goal is to evaluate the complete driven-tool assembly and determine the most practical service path based on its condition, application requirements, replacement availability and production timeline.
Live Tooling Inspection
Evaluation of bearings, gears, shafts, seals, tool interfaces and visible wear affecting driven-tool performance.
Repair & Rebuilding
Repair and rebuilding support for worn or damaged live tooling units, including qualifying internal components.
Bearing & Seal Replacement
Inspection and replacement support for bearings, seals and related wear components.
Shaft, Gear & Internal Component Service
Machining, restoration and replacement support for qualifying shafts, gears and internal drive components.
Sales & Replacement Support
Sourcing support for new, rebuilt, used, OEM and qualified replacement live tooling units.
Exchange Options
Exchange-unit support when a compatible unit is available and turnaround requirements favor replacement over repair.
Receive → Disassemble → Inspect → Approve → Rebuild or Source → Test
Driven-Tool Problems Require More Than Replacing a Bearing
Noise, heat or runout may point to one failed component, but the underlying problem may also involve gears, shafts, seals, alignment or the machine-side drive interface. NNG evaluates the condition of the entire unit so the service recommendation reflects the actual failure rather than only the most obvious symptom.

Repair, sales and exchange support based on the actual unit.
Live Tooling Units & Applications We Support
NNG supports a range of live tooling units used across CNC turning centers and multi-tasking machines. Service availability depends on the manufacturer, model, configuration, condition, technical information and parts availability.
Support for Current and Legacy Units
NNG may assist with obsolete or difficult-to-source live tooling when repairable components, drawings, dimensional information or qualified replacement options remain available.NNG works with a wide range of OEMs, machine generations and hard-to-source components. Available prints, technical records and sourcing resources can be especially valuable when conventional replacement channels are limited.
Application Review
Depending on the request, NNG may review machine information, turret type, unit manufacturer, drive configuration, tool interface, operating speed and failure symptoms.

The Right Path...
The right option depends on the unit’s condition, internal damage, repair history, replacement availability and production requirements.
Repair
Correct localized wear or component damage when the live tooling unit remains serviceable.
Rebuild
Restore the unit through disassembly, cleaning, bearing and seal replacement, component repair, reassembly and testing.
Exchange
Replace
Source a new, rebuilt, used, OEM or qualified replacement unit when repair is not practical.
LIVE TOOLING QUESTIONS
What Customers Need to Know
Answers to common questions about evaluation, testing, exchange availability and what to send with a service request.
What information should I provide?
Send the machine manufacturer and model, turret information, live tooling manufacturer and model, serial number, tool interface, symptoms, photos and required timing.
What live tooling problems can NNG evaluate?
NNG may evaluate excessive runout, noise, vibration, overheating, leakage, reduced torque, bearing wear, gear damage and poor tool engagement.
Does NNG repair both axial and radial live tooling?
Support may be available for axial, radial and other driven-tool configurations depending on the manufacturer, model and condition.
Are exchange units available?
Exchange availability depends on the manufacturer, model, configuration, tool interface and current inventory.
Can NNG support obsolete live tooling?
Support may be possible when the unit can be identified, repaired, measured or matched to a qualified replacement.
What testing is performed after service?
Testing may include rotational checks, runout inspection, leak evaluation, dimensional verification and functional testing appropriate to the completed work.
Does NNG sell new live tooling?
NNG may help source new, rebuilt, used, OEM or qualified replacement units based on application requirements and availability.
