// OVERVIEW

What is roll straightening?

Roll straightening feeds material through a 2-roll straightener that progressively works out runout, bowing, and other deviations — producing exceptional straightness and uniformity across a wide range of materials. It's the efficient way to bring bar stock true before it heads into final machining.

The process minimizes residual stress and improves dimensional accuracy and material stability for demanding industrial applications. As a bonus, 2-roll straightening also aids in descaling heat-treated materials — removing surface oxidation and improving overall workability.

// BEST USES

Where roll straightening fits

Bar & stock prep

Correct runout and bowing in bars before final machining or grinding.

Descaling heat-treated material

Removes surface oxidation from heat-treated stock and improves workability.

Roll straightening is intended for stock preparation, not finished shafts requiring ultra-precise tolerances. For tight finished-shaft straightness, see our press straightening service (.0005″/ft).
// WHY IT WINS

Benefits

Exceptional straightness & uniformity — consistent results across a wide range of materials.
Minimized residual stress — better long-term stability in the finished part.
Built-in descaling — cleans heat-treated surfaces and improves workability.
Efficient throughput — fast, repeatable prep for production volumes.

Roll straightening questions

What is roll straightening?

Roll straightening feeds material through a 2-roll straightener that works out runout and bowing, producing exceptional straightness and uniformity — ideal for prepping bar stock before machining.

What straightness does roll straightening achieve?

Roll straightening holds straightness to .0015″ per foot TIR or better.

Does roll straightening remove scale?

Yes. The 2-roll process also descales heat-treated material, removing surface oxidation and improving workability.
