摘要： A stuck locking pin is removed from a turbine rotor by forming an aperture in the locking pin. The diameter of the aperture is less than the diameter of the locking pin, such that a thin shell portion remains in the locking pin receiving slot of the rotor. The locking pin then can be easily removed by any suitable means, such as by driving a high-strength metal rod into the aperture. The driving force stretches the thin shell portion, which easily separates from the rotor.

摘要： Method and apparatus for electrochemically deburring a diesel injector nozzle workpiece having a gallery cavity and having a first fuel hole and an air hole intersecting the gallery cavity at a first location. A first electrode is inserted into the first fuel hole such that the electrode tip is near the first location. A post is inserted in the air hole into the gallery cavity. An electrolyte flow is directed through a first channel of the post to the gallery cavity and through a second channel of the post from the gallery cavity. A voltage potential is applied between the first electrode and the workpiece to remove burrs previously formed at the first location.

摘要： An electrode used as a tool in an electrochemical machining process to generate raised areas or ridges in the walls of a predrilled hole in an electrically conductive workpiece has an electrically conductive cylinder partially coated with an electrically insulating material in a pattern defining the raised areas to be formed. The pattern may comprise a plurality of spaced apart rings. An electrochemical machining method of drilling bulbs in the walls of a predrilled hole uses the electrode of the invention to greatly increase process efficiency.
