For smooth trouble-free, the punching tonnage should not exceed two-thirds of the rated capacity of the press. In multiple punching set-ups, the punches should be stepped by setting punches at different levels. If the punches are on two levels, the punching pressure requires may be divided by two. If they are set on three levels, the pressure may be divided by three.
