ABSTRACT:
A punching press according to the present invention employs a servo motor as the driving source of the punching operation to achieve fine control, and exhibits a performance which is equivalent to or higher than that of a conventional punching press which employs a hydraulic cylinder. A hammer member which performs the punching operation is coupled to a stroke member which performs a stroke motion. The stroke member is coupled to a motion converting unit which converts the rotational motion of a servo motor into a stroke motion.
