ABSTRACT:
An electrode holder particularly useful in electric discharge machining where it is required to attach quickly and accurately in succession a number of electrodes to the quill of the machine. One side of a housing of the electrode holder attaches to the quill while a threaded shaft protrudes from an opposite side. An opening in the housing provides access for rotating the shaft so that the thread end may be screwed into a threaded hole in one end of the electrode. Accurate alignment of the electrode is provided by alignment pins in the housing. Lubricating and cleaning fluid can flow from a bore in the quill through the shaft and to the electrode.
