ABSTRACT:
An electrically conductive arbor indexer shaft is coupled to an indexing D.C. motor by an insulator connector and the indexer shaft in an indexed position is tightly gripped by a resilient electrically conductive clamp connected to an electrically conductive support to which a buss is engaged for supplying electrical current to the arbor via the indexer shaft, clamp and support. During the ECM process, a workpart on the arbor is made an anode by current passing through the arbor indexer shaft, clamp, support and buss with the resilient clamp insuring sufficient electrical coupling of the arbor indexer shaft to the other upstream current carrying components.
