Abstract

An improved process for the manufacture of a tool which is used as a cathode in electrochemical machining of materials which comprises machining a metal piece having adequate electrical conductivity,to provide a hollow tube with a cross section similar to that of the profile of the material to be electrochemically machined,characterised in that drilling a hole near the edge of the hollow tube such that the hole extends to the entire length of the tube for uniform supply of electrolyte throughout the electrochemical machining,milling the ouside surface of the tube to the desired shape and size,slotting the surface of the said milled tube,insulating the inner surface of the said tube with an insulator pressure tube having a cross section similar to the inner profile of the tube,moulding the outside surface of the tube,with an insulator which may be same or different than that used for insulating the inner surface of the tube to get the tool.
