ABSTRACT:
The present invention relates to a method of cold rolling metal parts to achieve improved surface uniformity and hardening. The method comprises applying to the work piece a pulsating force at a frequency of from about 30 to 300 the duration of the pulses being at least twice the time between pulses. The pulsating force varies from about 10% to 100% above the minimum force necessary to achieve a smooth rolled finish. The method contemplates just statically rolling the work piece and thereafter applying the pulsing force which, in such instance may reduce to zero.
