摘要

The measuring press die (43) is supported on the concave spherical seat (12). The measuring shaft member (45) is arranged coaxially with the reference axis (α) between the measuring die (43) and the support table (16), and is linearly guided in the direction of the reference axis (α). I do. Then, while rotating the measuring die (43) about the reference axis (α), the measuring pressing die (43) is pressed against the measuring shaft member (45) by the load applying means. The actual load in the direction of the reference axis (α) added to (45) is measured by the load cell (48).
