ABSTRACT:
An electromachining process and apparatus includes providing both high-speed electroerosion functions for rapidly rough finishing a workpiece and electrodischarge machining functions for fine finishing by first using a rotary electrode to implement the high-speed electroerosion function, and then removing and replacing the rotary electrode with an EDM electrode to implement the electrodischarge machining functions.
