Abstract

Apparatuses and methods for toolless electrolytic deburring (100) are disclosed in which a charged electrolyte stream (134) flows through a hose (110) and nozzle (120) and can be selectively directed at a desired portion of an external or internal surface of a workpiece (102). The nozzle (120) or the workpiece (102) can be manipulated to vary the electrolytic deburring working gap so as to control the intensity of the electrolytic deburring and the portion of the workpiece that is electrolytically deburred. The electrolytic deburring is preferably performed in an enclosure (200) having a glove (210, 212) which has an electrical contact that can be used to electrically connect the workpiece (102) to the DC power supply anode(124) simply by gripping the workpiece.
