Abstract
A levelling apparatus which comprises a lower part and an upper part which is mounted to the lower part and which may be adjusted with respect to the lower part. The lower part is provided with reference elements for its definite positioning, and the upper part is provided with mechanisms for mounting a workpieceholder for a workpiece which is to be worked on by a machine tool especially a wire erosion machine. For ensuring an improved positioning of the workpiece relative to the erosion wire at elevated pressures of the rinsing fluid, the lower side of the upper part has a first beam structure and the upper side of the lower part has a second beam structure which is complementary to the first beam structure such that the beams of the first beam structure extend between the beams of the second beam structure.
