摘要： A machine has upper and lower die members which clamp a disk blank between them and maintain the disk blank axially on a machine vertical axis and planarly on a machine horizontal axis. The die members and disk blank are rotated via a main motor which drives one of the die members through a spur-ring gear configuration or directly along the machine vertical axis. Splitting and swaging tools are positioned to move along the machine horizontal axis to form the disk blank outer peripheral edge into a pulley groove while a splitting-swaging tool carried within a chamber formed by the die members splits and swages a disk blank bore to form upper and lower bearing retaining flanges. Various means for moving the splitting-swaging tool off of the machine vertical axis to a parallel axis are disclosed as well as various means for exact positioning of the disk blank axially on the machine vertical axis.
