Our calculators will help you determine if it makes sense to use flat form-rolling dies and, if your form-rolling machine capacity is adequate.
  The form-rolling calculators determine: how much a part will elongate or stretch after groove rolling, how long a flat die is needed for rolling a sharp cone point, what length flat die is required for form-rolling a full radius point and determining the correct form rolling die length for groove rolling.
  Our FAQ answers the most asked questions about flat die form-rolling applications. Call or e-mail our engineering staff for detailed information.
