[origin: EP2343138A1] The device has an inner molding tool is arranged coaxial to machine main axis (x) of a main spindle (1.1) that comprises a driver (11). The inner molding tool is axially positioned and/or axially moved relative to axial position of an outer molding tool (8), which is radially positioned or moved radially, during formation of a blank mold, which is formed as a rotationally symmetrical hollow body. The inner molding tool has a spherical, outer contour that has a set of conical, concave, and/or convex transitions. An independent claim is also included for a method for producing workpieces from a blank mold.
