Abstract
A punch press having a rear address configuration is described in which a forward facing carriage cross slide is mounted within the throat space of a punch press main frame and an auxiliary turret frame mounts the punch and die rotary turrets separately from the main punch frame, avoiding the need to prevent turret misalignment by main frame deflection during punching. Separate turret modules also allow matching different turret configurations to various punch press configurations. A turret module having different diameter independently driven upper and lower turrets is also disclosed, allowing a greater number of dies than punches to be stored to allow any several dies to be mated with a particular punch for proper punching with various materials.
