Remotely actuated metal disintegration machine apparatus.

摘要

A metal disintegration apparatus (10) for performing machining work using an electrode (30) on a portion of a workpiece (P) in a confined inaccessible location includes electrode means (30), electrode holder means (32) for movably holding the electrode means (30) and elongated means (34) for positioning and supporting the electrode holder means (32) at a desired remote location. Vibration feed means (20) are coupled to the electrode means so that the electrode (30) can be vibrated relative to the electrode holder means (32) and advanced so that the electrode (30) can perform arc-machining. The vibration feed means (20) is located at a location remote from the electrode means (30); the metal disintegration apparatus (10) is ideally suited for work at inaccessible locations such as those encountered in steam generators of nuclear reactors.
