Abstract:

The present invention is directed to an improved mechanism for use in electrochemical machining cells for maintaining an essentially constant and uniform electrolyte flow gap around the tool during displacement of the tool into a workpiece to be electrochemically machined. The mechanism of the present invention is particularly adapted for use with tools having configured surfaces such as tapered sidewalls which would form gaps of nonuniform size with the workpiece during machining which would result in nonuniform flow of electrolyte and other deleterious operating conditions. The mechanism of the present invention is a movable plate arrangement disposed contiguous to the tool to provide an essentially constant and uniform-sized gap thereabout. As the tool is displaced into the workpiece, a cam associated with the tool contacts the plate to displace a section thereof in a direction orthogonal to the movement of the tool so that as the tapered section of the tool passes the plate, the plate is moved to maintain the gap at a constant size between the plate and the tool for assuring uniform electrolyte flow around the tool during the machining operation.
