DECLARATION UNDER ARTICLE 19 (1) PCT

Advantage of one-piece adapter pieces: lower error tolerances with respect to the dimensions of the machined workpieces; In contrast, adapters made of several parts lead to higher error tolerances, since the dimensions between the respective parts can lead to additional errors in the dimensions (addition of

Incorrect dimensions).

 Advantage that the respective adapter piece and the respective workpiece are automatically adjusted and processed by the same shaping device: The

Shaping device is used efficiently.
