... main frame. The ram stroke is shorter than that of a forging hammer or a hydraulic press. Ram speed is greatest at the center of the stroke, but force is greatest at the bottom of the stroke. Because of the short stroke, mechanical presses are best suited for low profile forgings. Capacities of...
