ABSTRACT:
A fixture for workpieces which are poorly adapted for direct clamping on a machine tool comprises a casing having an upper part and a lower part. The casing has a cavity whose shape roughly corresponds to the contour of the workpiece. The remaining interstitial space or crack between the inner casing wall and the workpiece is filled with a hardenable casting material so that the workpiece is securely held when the casting material sets around it. For clamping of the securing body onto a grinding machine, lathe, or other machine tool, the casing comprises a clampable portion with reference surfaces.
