Deep Rolling Tooling Technology

Deep Rolling is the only process that induces residual compressive stresses and cold work while burnishing the workpiece’s surface to a high quality finish.

Deep Rolling significantly improves the surface characteristics of metal components subject to dynamic loading, increasing fatigue strength and service life.

Deep Rolling is especially well suited for treating rotationally symmetrical parts.

However, with modern tooling technology Deep Rolling can be used to treat free-form surfaces and thin-walled components as well.

Deep Rolling can be used to treat:

• Material fatigue due to dynamic loading
• Stress concentration or notch effect
• Low fatigue strength due to residual tensile stress
• Stress corrosion cracking
• Fatigue due to rolling contact
