ABSTRACT:
A micro-roll forming device for providing a cylindrical blank metal article with a minute convexoconcave bearing surface, comprises a powered article holding structure that, when energized, rotates the cylindrical blank metal article about its axis; a forming tool that includes a form roller with a corrugated circular ridge; a tool holding structure that holds the forming tool in such a manner that the corrugated circular ridge of the form roller is directed toward and in contact with an outer surface of the cylindrical blank metal article rotatably held by the article holding structure; a biasing member that is incorporated with the tool holding structure to press the form roller against the outer surface of the cylindrical blank metal article with a given pressing force; and a powered moving structure that, when energized, moves at least one of the article holding structure and the tool holding structure in such a manner that the selected one moves in both a first direction perpendicular to an axis of the unselected one and a second direction parallel with the axis of the unselected one.
