A machine, method and tooling to precision cold-form roller blanks for
anti-friction bearings. The machine is a multistage progressive former
using floating die cavities to enable simultaneous shaping of the ends of
the roller with high accuracy and without flash. The tools and staged
forming create an improved roller with an advantageous grain pattern and
devoid of structural defects previously attributable to the presence of
sheared end face material in the radiused corners of the blank and flash
at its mid-section.
