Deep rolling of valve
Task
Replace slide grinding (vibratory grinding); roller burnishing to Rz < 2 μm yield residual compressive stress
Solution
Burnishing and yielding residual compressive stresses by deep rolling of the tulip area with EG45-40M tool

User benefits
- Reduce the process costs of about 25%
- Process time ampulated of about 30%
- Fatigue strength reached
