The Bradbury Group — Inspection Checklist for Used Equipment

Purchasing a used Bradbury roll forming or coil processing system can be a strong investment — but only if the machine is thoroughly inspected.

Purchasing a used Bradbury roll forming or coil processing system can be a strong investment — but only if the machine is thoroughly inspected.

Heavy industrial equipment may appear solid externally while hiding:

• Shaft misalignment

• Frame twist

• Electrical obsolescence

• Hydraulic instability

• Worn tooling

• Safety compliance gaps

This page provides a structured inspection checklist designed specifically for used Bradbury systems, helping buyers reduce risk before committing to purchase.

Structural & Frame Inspection

What to Check:

☑ Frame straightness (visual & measured)
☑ Base plate cracks or weld fatigue
☑ Corrosion or rust (especially underneath)
☑ Anchor bolt damage
☑ Machine leveling condition
☑ Signs of stress deformation

Red Flags:

• Visible frame twist

• Weld repairs without documentation

• Uneven stand alignment

• Excessive vibration marks

Frame integrity is critical — structural defects are expensive to correct.

Roll Stands & Shafts

Inspect:

☑ Shaft straightness (run-out test if possible)
☑ Bearing play
☑ Roll stand mounting tightness
☑ Keyway wear
☑ Shaft scoring
☑ Endplay movement

Red Flags:

• Shaft wobble during rotation

• Excessive bearing noise

• Uneven roll spacing

• Bent shafts

Shaft replacement can be costly in heavy gauge systems.

Tooling Condition

Evaluate:

☑ Roll surface finish
☑ Pitting or corrosion
☑ Edge wear
☑ Profile calibration accuracy
☑ Coating damage
☑ Alignment marks

Red Flags:

• Deep scoring

• Uneven roll wear

• Flange deformation

• Missing tooling components

Tooling replacement may cost tens of thousands depending on complexity.

Electrical System & PLC

Verify:

☑ PLC model and age
☑ HMI functionality
☑ Spare PLC module availability
☑ Wiring organization
☑ Panel cleanliness
☑ Electrical labeling
☑ Alarm history

Red Flags:

• Obsolete PLC platform

• Exposed wiring

• Burn marks

• Frequent unexplained alarms

Older PLCs may require full retrofit.

Drive System & Motor

Test:

☑ Motor smooth startup
☑ VFD response
☑ Gearbox noise
☑ Coupling wear
☑ Chain condition
☑ Current draw under load

Red Flags:

• Grinding noise

• Chain slack

• Overheating motors

• Vibration at speed

Drive system failures create costly downtime.

Hydraulic System (If Applicable)

Inspect:

☑ Oil level & cleanliness
☑ Pump pressure stability
☑ Hose condition
☑ Cylinder leakage
☑ Valve response
☑ Oil temperature

Red Flags:

• Pressure drop during punch

• Oil contamination

• Slow cylinder return

• Pump cavitation noise

Hydraulic rebuilds can be expensive.

Punch & Shear Systems

Check:

☑ Punch timing accuracy
☑ Blade sharpness
☑ Cut length consistency
☑ Punch alignment
☑ Shear burr levels
☑ Encoder feedback accuracy

Red Flags:

• Hole misalignment

• Excessive burr

• Blade chatter

• Punch delay

Punch timing errors often signal control or encoder problems.

Safety Systems & Compliance

Confirm:

☑ Emergency stops function
☑ Guarding intact
☑ Interlocks operational
☑ Safety PLC present (if applicable)
☑ Labeling clear
☑ Risk assessment documentation

Red Flags:

• Missing guards

• Bypassed safety circuits

• Faulty interlocks

Safety upgrades may be required to meet modern standards.

Automation & Synchronization

Observe:

☑ Speed stability
☑ Punch-feed synchronization
☑ Encoder tracking
☑ Recipe functionality
☑ Emergency stop recovery

Red Flags:

• Inconsistent length

• Automation lag

• Control drift

• Random stop events

Automation instability is often hidden until production testing.

Performance Testing (If Possible)

Always attempt to:

✔ Run actual material
✔ Test at multiple speeds
✔ Measure dimensional accuracy
✔ Check repeatability
✔ Verify hole alignment
✔ Confirm scrap rate

Static inspection alone is insufficient.

Documentation Checklist

Request:

☑ Original manuals
☑ Electrical schematics
☑ Maintenance logs
☑ Spare parts history
☑ Tooling drawings
☑ PLC program backup
☑ Service records

Missing documentation lowers value and increases risk.

Spare Parts & Obsolescence Review

Before purchase:

☑ Confirm PLC part availability
☑ Check motor model support
☑ Review hydraulic component sourcing
☑ Verify tooling replacement feasibility

Obsolete parts can make cheap machines expensive.

Estimate Hidden Cost Before Buying

After inspection, calculate:

• Tooling refurbishment cost

• PLC upgrade cost

• Safety compliance upgrade cost

• Hydraulic rebuild cost

• Drive system repair cost

• Installation & freight cost

A low purchase price can double once repairs are factored in.

Quick Pre-Purchase Risk Scoring

Rate each category 1–5:

Low combined score = high risk.

Conclusion

A used Bradbury roll forming system can offer significant value — but only after a structured, technical inspection. Mechanical wear, electrical obsolescence, tooling damage, and safety gaps can dramatically change the true cost of ownership.

Machine Matcher provides independent inspection and advisory services to ensure buyers understand the full condition, risks, and upgrade potential before committing to a used purchase.
