Abstract
The invention relates to an apparatus for manufacturing a three-dimensional, shaped graphite electrode (3) utilizing a three-dimensional, shaped file (4), moved toward one another (filing stroke) while executing an orbital relative movement between the shaped file and the three-dimensional, shaped electrode blank until such time as the contour of the three-dimensional, shaped electrode corresponds, with tolerance, to a negative copy of the contour of the shaped file. During the filing process, graphite particles filed off by the shaped file are flushed out of the working gap (7) formed between the shaped file and the three-dimensional, shaped electrode with the aid of a flushing fluid. The shaped file, which has an outer wall (10) pointing upward and surrounding it in pan-like fashion, the upper rim (12) of which is at a higher level than the highest point on the contour of the shaped file, is secured to a work plate (1) or the like executing orbital movements, while the three-dimensional, shaped electrode blank is secured to a ram plate (2) disposed above the work plate.
