Abstract
The subject of the invention is a retaining plate for a machine tool work piece, where the machine tool is equipped with a tool, e.g. an erosion wire, that can be moved in th z-direction of a work area, and where the work area is bounded by an xy-plane that is perpendicular to the z-axis, and with a work table whose work surface is in a specific position relative to the xy-plane and which is arranged in the direction of movement of the tool. In order to provide a holding mechanism that is particularly suitable for wire EDM-machines, and which allows for work piece transition any number of times without loss of alignment precision, a first plane section of the retaining plate with at least one opening for inserting the work piece, as well as retaining mechanisms for the work piece are provided, as well as elements on the second section of the retaining plate that are suitable to function together with mating elements on a chuck mounted on the work table for precise positioning of the first section within the work area.
