Many different version of the punching system exist. Hydraulic, hydramechanical, and air driven. The two mechanical rams use a flywheel driven by an electric motor to develop tonnage. In a hydramechanical system a small hydraulic pump delivers oil to a solenoid which when activated causes the clutch to engage generating a punch cycle.
Newer machines primarily use hydraulic cylinders with smart controllers to punch.
