International Classification:

B23H 1/00

US Classification:

219 6911, 219 6914, 219 6917

Abstract:

The hand-held electro-discharge device to remove boluses of material from a workpiece. In some implementations a conductive electrode and its supporting ground pin are immersed in a dielectric fluid contained in a hood or cavity near or at the electrode's distal tip an removably sealed to a conductive workpiece. A flushing inlet and outlet in fluid communication with said hood provide a flushing fluid, which may also be a dielectric fluid to remove FOD and cool.

B23H 1/00

US Classification:

219 6915, 219 6917

Abstract:

The hand-held electro-discharge machining fastener removal device of this invention brings an EDM electrode and its supporting ground pin and dielectric fluid structure to a fastener in a workpiece, such as an aircraft fuselage. The hand-held device brings the dielectric fluid, power supply, and control system structure to the fastener in a compact tool to permit EDM machining to be brought to large structures.
