An electrolytic processing apparatus configured for processing a hole of a work piece. The electrolytic processing apparatus includes a work platform, an electrolyte providing device and an electrolytic electrode. The work platform includes a loading platform and a flow channel. When the loading platform loads the work piece, the position of the flow channel is corresponding to that of the hole. The electrolyte providing device connects to the flow channel to provide an electrolyte to the hole through the flow channel. The electrolytic electrode is configured relative to the work platform and moves in a direction perpendicular to the loading platform. When the loading platform loads the work piece, the electrolyte flows through the hole and the electrolytic electrode moves in the hole in a variable speed to process the inside surface of the hole by electrolytic process, thereby forming a characteristic shape of the hole.

An electrochemical machining assembly for boring a passage in an electrically conductive workpiece. The electrochemical machining assembly includes an electrochemical machining tool having a telescoping collar with an articulating head coupled thereto.
