Why 1940s Bliss Stamping Presses Still Punch 120 Parts/Minute While Modern Need Daily Calibration

Why 1940s Bliss Stamping Presses Still Punch 120 Parts Per Minute While Modern Servo Presses Need Daily Calibration E.W. Bliss stamping presses from the 1940s achieved production rates of 120+ parts per minute using massive flywheels, mechanical crankshafts, and simple cam-operated feed systems that ran continuously for decades without adjustment. These presses featured cast iron construction weighing several tons, mechanical clutch and brake systems, and straightforward electrical controls with minimal failure points. Operators could maintain consistent production speeds and part quality for entire shifts without stopping for calibration or computer adjustments. Many Bliss presses from the 1940s remained in continuous production through the 2000s, stamping millions of parts with only routine lubrication and occasional mechanical adjustment. Modern servo stamping presses require daily calibration of electronic systems, frequent software updates, and constant monitoring of sensors and computers that cause production delays and quality problems that the rock-solid mechanical Bliss presses never experienced.
