Abstract
A dual cone or single cone work piece is placed inside a pair of locating surfaces so that it is accurately held within a framework defined by these locating surfaces. A electrode is then inserted inside the cone, and is movable within the cone to accurately set the gap between the electrode which will find the groove pattern to be formed on the cone surface. An electrolyte is then pumped through the gap between the cone and the electrode.
