Overview

Mechanical straightening is used to correct distortion in metal components caused by welding, machining, forming, or heat treating processes.

We have a range of straightening presses up to 150 ton capacity with the ability to straighten:

  • Rounds

  • Plates

  • Square Stock

  • Castings

  • Fabrications

Why Mechanical Straightening Matters

Distortion can occur at multiple stages of production — correcting it is critical before final machining or assembly.

  • Restore dimensional accuracy
  • Ensure proper fit and alignment
  • Reduce rework and machining time
  • Improve overall component performance
  • Prepare parts for final processing or installation

Controlled Straightening Process

Mechanical straightening is performed using specialized equipment designed to apply controlled force at precise points along a component. Each part is evaluated individually to determine the best approach for correcting distortion while maintaining material integrity and required tolerances. Our team uses experience and proven techniques to ensure consistent, repeatable results — even on large and complex fabrications.

Integrated Processing Advantage

Many components require multiple processes to achieve final specifications. By combining flame hardening, stress relieving, and mechanical straightening under one roof, Chicago Flame Hardening provides a more efficient and coordinated approach to production.

This reduces handling, shortens lead times, and ensures better overall consistency across all stages of processing.
