Maintenance Tips to Extend the lifespan of Your Cut to Length Line

Introduction: Why Cut to Length Line Maintenance is Mission-Critical

Cut to length line is a major investment for any metal processing facility. Whether you're working with stainless steel, galvanized coils or copper sheets, keeping the machine in top shape ensure high precision, low scrap rates, and consistent throughput.

Preventive vs. Reactive Maintenance: Which Saves More?

Preventive Maintenance (Recommended)

• Scheduled, routine inspections
• Lower long-term cost
• Prevents unexpected breakdowns

Reactive Maintenance (Risky)

• Only performed after failure
• Often results in longer time
• Higher spare parts and labor cost

Daily, Weekly, Monthly Maintenance Checklist:

Daily Maintenance Tasks:

• Check for unusual noise or vibration
• Wipe down exposed metal surfaces to prevent rust
• Clear scrap bins and remove metal dust from slitter and shear
• Verify blade alignment and inspection for visible wear

Weekly Maintenance Tasks:

• Inspect and lubricate key components:
  • Blade shafts
  • Leveler rollers
  • Shear slides
  • Bearings
• Check hydraulic fluid levels and look for leaks
• Test emergency stop and safety sensors

Monthly Maintenance Tasks:

• Calibrate the measuring system and encoder
• Tighten all bolts and anchor points
• Inspect tension control system 
• Clean air filters and cooling fans in electrical cabinets

Blade & Blade Shaft Care: Extend Their Working Life

One of the most critical components of cut to length line is the rotary shear blade and blade shaft assembly.

Blade Maintenance Tips:

• Rotate or flip four-sided blades regularly to use all edges
• Maintain correct blade gap to avoid burr formation
• Avoid overheating and lubricate during high-speed runs

Lubrication System: Keep Things Running Smooth

Lubrication is essential to avoid friction wear and heat buildup. Our CTL lines come with centralized forced lubrication systems for consistent oil delivery
