ABSTRACT:
A torque converter part having a three dimensional configuration and adapted to be assembled together with a series of torque converter pump blades is formed by a process which includes forming, within a press, slits, for receiving ends of the blades, in a flat blank within a press, deburring, within the press, to remove the burrs formed during slitting, so as to form half-finished work. The half-finished work is cut from the blank and deep drawn thereby obtaining a toroidal torque converter part. Since the deburring is conducted on the work while the work is still flat, burrs are removed easily and promptly with a high degree of uniformity.
