ABSTRACT:
An electrochemical machining apparatus and method for machining a workpiece. The apparatus provides a pulse of electric power, which is conducted from the workpiece, to an electrolyte flowing through a gap, and then to an electrode. Material is eroded from the workpiece when the pulse of electric power is applied, thus machining the workpiece. The apparatus includes a power supply to supply the electric power and a switching portion for producing the pulse by switching the electric power ON and OFF. The switching portion is capable of producing a pulse of electric power with a pulse duration of about 2 microseconds and a current of at least about 2800 amperes.
