Troubleshooting Common 3 Roll Bending Machine Problems
                     Troubleshooting Common 
3 Roll Bending Machine 
Problems
Keep your metal plate rolling operations running smoothly with 
expert troubleshooting guidance. From misalignment to hydraulic 
issues, learn how to identify and fix problems quickly.
Understanding Your Machine
How It Works
A 3 Roll Bending Machine uses three rollers to shape metal plates. 
Two rolls grip the plate while the third applies pressure to create 
precise bends.
This setup delivers high precision for thick steel or aluminum 
sheets, making it essential for modern manufacturing.
Warning Signs to Watch For
Uneven Bends Plate Slipping Hydraulic Leaks
Inconsistent curves or irregular Metal sheets failing to grip Oil seepage around hoses, seals, 
shapes in finished plates properly during rolling or connections
Unusual Noise Control Errors
Unexpected vibrations or sounds during operation Panel malfunctions or error codes appearing
Spotting these symptoms early prevents costly downtime and maintains production schedules.
Top Issues and Quick Fixes
Roll Misalignment
1 Causes: Worn bearings, loose bolts, uneven pressure
Fix: Check alignment with straightedge, tighten bolts, replace 
bearings, use manufacturer settings
Uneven Bending
2 Causes: Incorrect feeding, uneven pressure, material thickness variations
Fix: Feed plates straight, adjust top roll pressure uniformly, pre-
check material thickness
Plate Slipping
3 Causes: Worn rollers, insufficient pressure, dirty surfaces
Fix: Clean rollers and plates, increase pressure carefully, re-coat 
roller surfaces if degraded
Hydraulic System Troubleshooting
Common Hydraulic Issues
• Oil leaks around hoses and seals
• Low hydraulic pressure affecting performance
• Slow or jerky roll movement
Solutions
• Inspect for leaks and replace damaged seals
• Refill or replace hydraulic oil per recommendations
• Check pump and filters regularly
• Contact supplier for persistent problems
Preventing Motor and 
Electrical Problems
Overheating Motors
Causes: Overloading, poor ventilation, faulty wiring
Prevention: Stay within rated capacity, clear debris, 
schedule electrical inspections
Control Panel Issues
Problems: Unresponsive buttons, error codes, power 
surge damage
Fixes: Reset system, use surge protectors, replace 
worn switches and sensors
Maintenance Best Practices
01 02
Regular Lubrication Service Logging
Keep moving parts well-lubricated to reduce friction and wearMaintain detailed records of all repairs and maintenance activities
03 04
Operator Training Safety Checks
Train staff on proper usage to minimize wear and prevent damDaisgceonnect power before troubleshooting; test-run after 
repairs with small plates first
05 06
Genuine Parts Scheduled Service
Use authentic spare parts from trusted suppliers like Follow manufacturer's maintenance schedule; service 
Himalaya Machinery hydraulic systems every 6-12 months
When to Call the Experts
Signs You Need Professional Help
• Persistent hydraulic leaks that won't stop
• Severe electrical faults or repeated failures
• Major repairs like roll replacement
• Recurring problems despite troubleshooting
Key Takeaway: Preventive maintenance and proper 
training are your best allies. Contact manufacturers 
like Himalaya Machinery or your 3 Roll Plate Bending 
Machine supplier for expert guidance and original 
parts.
