Abstract
An electrochemical machine of the type having a workpart shroud around the workpart except for the portion thereof to be received in an electrolyte chamber with the shroud and electrolyte chamber substantially enclosing the workpart during machining is provided with opposing clamps on an electrolyte chamber member to cammingly engage opposite lateral sides of the shroud to hold it against the electrolyte chamber member to reduce high pressure electrolyte leakage. A venting conduit system is provided from the shroud through mated engaged surfaces of the shroud and electrolyte chamber member to an electrolyte drain in the electrolyte chamber to vent gases from the shroud during machining. Flow of high pressure electrolyte through the electrolyte chamber and drain creates a suction on the shroud interior to cause venting of gases, such as hydrogen, therefrom.
