摘要
This is an attachment that rotates a spark eroding electrode 4, in a circular path. The attachment is electrically insulated from the machine head 2, 6, and 7, and may be driven through a rack and pinion or other gearing or friction means. The attachment may be used to machine gates in injection moulds.
