Abstract: An electrode carrier for mounting the electrodes of an electrode-erosion hining device having the capabilities of effectively clamping a plurality of needle-type electrodes in a short amount of time, without applying excessive forces to the electrodes. The electrode carrier has a mounting body defining a cavity, as well as passageways, through which the electrodes pass such that they extend through a cavity. A deformable elastic material is disposed within the cavity in contact with portions of the electrodes. A clamping piston is urged into contact with the deformable elastic material such that it applies a compression force on the material causing it to deform and clamp the electrodes in the mounting body.
