PROBLEM TO BE SOLVED: To provide a circularity measuring apparatus capable of measuring circularity of a spherical measurement object with high accuracy, and a measurement object fixture of the same.SOLUTION: When circularity of a spherical work W is measured, a spherical work fixture 50 is installed on the mount base 12 of a circularity measuring apparatus and the work W is mounted on a work mounting unit 100 on the upper surface of the spherical work fixture 50. The work mounting unit 100 is provided with support balls for supporting the work W at three points and the work W is coupled to a weight member 84 via a suction pad 96 so that the work W does not move by measurement pressure.SELECTED DRAWING: Figure 3 |
