ABSTRACT:
An expandable, grip tip having a head with a knurled peripheral surface is expanded within a predrilled opening in a graphite electrode blank to secure the grip tip to the electrode blank. The grip tip is then mounted in an electrode shank, with the electrode blank flush against the end of the shank to seal off dielectric fluid. To enable the mounting of the electrode blank onto the shank, the grip tip is locked in a loading fixture and the electrode blank mounted on the knurled head of the grip tip. A projection on the loading fixture recesses the knurled head of the grip tip from an end face of the electrode blank. When mounting the grip tip and electrode blank onto the shank, there is always a space between the end of the shank and the knurled head of the grip tip. This ensures that the electrode blank is mounted squarely and flush against the end of the shank.
