Abstract
A mount for interposition between an electrode holder and an electrode for electrical discharge machining (EDM). The mount is cast from material such as aluminum or zinc. The mount has a shank portion that is connectable to the electrode holder and a connector portion or tip portion that is connectable to the electrode. The tip portion has a gluing surface that is dimensioned to be glued with a corresponding surface on the electrode. A plurality of deformable ears cast onto the gluing surface of the mount project outward and deform in contact with the electrode when the electrode and the mount are connected and bonded by glue, to thereby provide good electrical contact therebetween. The tip portion may also include grooves cast therein for receiving glue thereby improving the glue bond strength between the electrode and the mount. The mount includes an axial passage to provide for dielectric fluid flow therethrough. The shank portion includes a recess increasing the number of contact points between the mount and the electrode holder. A raised lip may be cast into the mount around the axial passageway to act as a seal between the electrode holder and the mount to prevent leakage of dielectric fluid therebetween.
