摘要：A workpiece-supporting table of an electro erosion machining equipment isprovided with a mechanism for subjecting the workpiece to a circling motion of
continuously variable radius during operation from zero to a maximum value. The sametool electrode can be used, without withdrawal from the work, for coarse machining atfirst and fine machining under circling movement immediately thereafter.
