摘要

A punch press having multiple punch tool rotatable turrets wherein at least one of the punch tools on each of upper and lower turrets is indexable to different angular orientations. Rotation of the indexable punch tools is accomplished by a slideably mounted motor for engagement with a timing pulley, which through a timing belt and a harmonic gear drive, acts to rotate the punch tools. A brake and position sensors are also provided. Synchronization of punch and die orientation is achieved through servos and control.
