Two, cylindrical structural that rotates and helical groove structure that can be in electrochemical machining of the present utility model have " holding bits " and " chip removal " effect, even also be difficult for being short-circuited under little machining gap, are difficult for the workpiece surface of burning.Thereby working accuracy is significantly improved.
Three, the cylindrical structural that rotates that can be in electrochemical machining of the present utility model, because in electrochemical machining process, the little place of distance current density is big between electrolysis tool-electrode and workpiece, electrolytic action is obvious, as long as the time is enough, through the short period of time as electrolysis in 3~5 minutes after, workpiece will be tending towards equating with the distance of this tool-electrode that rotatablely moves, and make processed workpiece hole circle degree error almost nil.Therefore, no matter whether the cylindrical of workpiece hole, this tool-electrode has deviation from circular from, whether the workpiece hole installation site overlaps with the center of turning circle of this tool-electrode, does not nearly all influence processed workpiece hole circle degree, the utlity model has the especially little advantage of processing deviation from circular from.
