White Paper: High-Precision Roll Marking on Round Steel Fittings

Introduction

Manufacturers often require permanent, readable marks on steel components to ensure traceability, quality control, and compliance with industry standards. Achieving consistent, high-quality marks on coated parts can be challenging, particularly when marking small characters on curved or irregular surfaces. Columbia Marking Tools (CMT) provides reliable roll marking solutions designed for durability, precision, and speed, even on coated steel fittings.

Application Overview

Part: Round steel fitting
Material: Steel
Marking Requirement: Two lines of variable information, 1/8″ characters, with sufficient depth to remain readable after coating

Machine Used: CMT 860 All-Air Roll Marking Machine with A43 Cylinder (4,300 lb force)
Air Pressure: 50 psi
Cycle Time: 2 seconds

Large Cast Iron Bolt

Technical Considerations

  • Character Size & Depth: 1/8″ characters with deep impression ensure readability after coating
  • Material Handling: Steel fittings are accurately positioned to maintain consistent marking alignment
  • Machine Configuration: The 860 all-air roll marking machine provides 4,300 lbs of force with precise control via the A43 cylinder
  • Cycle Efficiency: 2-second marking cycle enables high-volume production without compromising quality

Benefits of CMT Roll Marking

  1. Durability: Marks remain legible after coating or finishing processes
  2. Consistency: Uniform depth and character clarity across all parts
  3. Speed: Quick cycle times support high-volume production
  4. Flexibility: Two lines of variable information can be marked easily without changing tooling
  5. Cost Efficiency: Air-driven roll marking reduces maintenance and tooling costs

Conclusion

CMT roll marking machines offer a reliable, efficient, and cost-effective solution for marking steel fittings and other metal components. With precise depth control, rapid cycle times, and durable marks suitable for post-coating readability, manufacturers can improve traceability and maintain consistent quality across their production lines.
