Programmable magnetic repulsion punching apparatus

A punch apparatus for punching hole patterns in thin sheet material comprising;

• a housing having a liquid-cooled cavity therein, said cavity containing a liquid cooling medium;
• a coil mounted in said liquid-cooled cavity and immersed in said liquid medium;
• a driver disk made of a highly conductive material mounted in said liquid-cooled cavity and immersed in said liquid medium, said driver disk mounted adjacent to said coil;
• a driver button located outside of said liquid-cooled cavity but in communication with said driver disk;
• a punch element for perforating thin sheet material, said punch element aligned with said driver button;
• a means for energizing said coil with a pulse of electrical energy for generating flux linking said driver disk and said coil to repel said driver disk from said coil, thereby translating said driver button and said punch element, causing said punch element to perforate a thin sheet of material.
