The Bradbury Group — Refurbishment & Modernization Considerations

Refurbish, modernize, or replace?

For owners of aging roll forming and coil processing systems, the key strategic question is often:

Refurbish, modernize, or replace?

Heavy-duty systems from manufacturers like The Bradbury Group are frequently built with robust structural frames that can last decades. However, automation, drive systems, hydraulics, and safety components may become outdated or worn long before the core mechanical structure fails.

This page provides a structured guide to evaluating refurbishment and modernization opportunities — and determining when they make commercial and technical sense.

What Is Refurbishment vs Modernization?

Although often used interchangeably, they are slightly different:

Refurbishment

Restoring existing components to original operating condition.

Examples:

Replacing bearings
Re-machining shafts
Rebuilding gearboxes
Refacing roll tooling
Replacing hydraulic seals

Modernization

Upgrading systems to newer technology or standards.

Examples:

PLC upgrade
Servo feed retrofit
Safety PLC installation
HMI replacement
Drive motor upgrade
Data connectivity integration

Refurbishment restores.
Modernization improves.

Step 1: Structural Integrity Assessment

Before investing in upgrades, inspect:

✔ Frame straightness
✔ Base plate integrity
✔ Stand mounting surfaces
✔ Shaft alignment
✔ Structural weld condition

If the structural foundation is compromised, replacement may be more economical.

Common Refurbishment Areas

Roll Stands & Shafts

Bearing replacement
Shaft straightening
Keyway repair
Stand alignment recalibration

Mechanical refurbishment improves forming accuracy.

Tooling Restoration

Surface regrinding
Re-hardening (if feasible)
Profile recalibration
Replacement of worn calibration passes

Tool refurbishment can extend life significantly.

Drive System Reconditioning

Gearbox rebuild
Motor bearing replacement
Chain replacement
Coupling alignment

Drive refurbishments restore torque stability.

Hydraulic System Overhaul

Pump replacement
Seal kits
Valve reconditioning
Oil system cleaning
Cooling upgrade

Restores punch consistency and reduces leaks.

Common Modernization Opportunities

PLC & HMI Upgrade

One of the most impactful improvements.

Benefits:
✔ Improved diagnostics
✔ Spare part availability
✔ Recipe management
✔ Remote support capability
✔ Better safety integration

Older PLC platforms often become obsolete.

Servo Feed Integration

Upgrading mechanical feeds to servo control improves:

✔ Punch accuracy
✔ Length consistency
✔ Production speed
✔ Reduced scrap

Especially valuable for precision lines.

Safety Compliance Upgrade

Modernization may include:

✔ Safety PLC installation
✔ Guard redesign
✔ Interlock integration
✔ Light curtains

Ensures compliance with current standards.

Data & Connectivity Upgrade

Add:

✔ Production monitoring
✔ Maintenance tracking
✔ ERP integration
✔ Remote diagnostics

Transforms older lines into smart production assets.

Economic Evaluation: Retrofit vs Replacement

Before committing, compare:

Factor	Refurbish/Modernize	Replace
Upfront Cost	Lower	Higher
Downtime During Work	Moderate	High
Structural Lifespan	Extended	Full lifespan
Technology Level	Upgraded	Fully modern
Warranty	Limited	New system warranty
Long-Term Efficiency	Improved	Maximum

If the machine frame and shafts are strong, modernization often delivers strong ROI.

When Replacement Is the Better Option

Modernization may not be ideal if:

Frame is twisted or cracked
Shaft damage is severe
Machine is undersized for production demand
Electrical cabinet is severely outdated
Spare parts are unavailable
Production volume has doubled

At some point, structural limits prevent meaningful upgrade.

Pre-Modernization Technical Audit

Before investing:

✔ Conduct structural inspection
✔ Measure shaft alignment
✔ Review drive system torque
✔ Test hydraulic pressure stability
✔ Evaluate PLC support status
✔ Estimate spare part availability
✔ Assess safety compliance gaps

A technical audit prevents overspending.

Downtime Planning for Modernization

Refurbishment projects often require:

Scheduled shutdown
Electrical rewiring
Re-commissioning
Calibration testing
Operator retraining

Staged upgrades reduce production disruption.

Impact on Total Cost of Ownership

Strategic modernization can:

✔ Extend machine life 10–20 years
✔ Reduce scrap
✔ Improve energy efficiency
✔ Lower downtime
✔ Increase resale value
✔ Improve operator safety

Poorly planned upgrades increase system complexity and maintenance cost.

Spare Parts & Obsolescence Strategy

When modernizing, ensure:

☑ New PLC platform is widely supported
☑ Spare drives are available
☑ Encoder compatibility is ensured
☑ Electrical panel wiring is properly documented
☑ Safety components meet regional standards

Modernization should reduce obsolescence risk.
