Abstract: A balanced panel punch drive system. The system includes a main hydraulic drive including an outer casing forming an internal housing and a main piston slidably disposed within the internal housing. A main fluid chamber, a first output chamber and a second output chamber are formed within the internal housing. A pump is fluidly connected to the main fluid chamber by an input line. A first die hydraulic cylinder and a second die hydraulic cylinder each have an outer casing forming an internal housing and a die piston slidably disposed within the internal housing. An opening is formed through an end of the outer casing sized to receive a distal end of the die piston therethrough. A first output line fluidly connects the first output chamber to the first die hydraulic cylinder and a second output line fluidly connects the second output chamber to the second die hydraulic cylinder.
