Currently, measurement of effective diameter for ball screw shaft is carried out by handwork. So it requires a highly skilled operator and high costs. In this paper, an automatic instrument has been established. The automatic instrument, which is controlled by computer, can measure the effective diameter of ball screw along whole length and any point per one revolution, to increase productivity and cost effectiveness. The instrument applies the three-wired method, which is used in practical field. In order to detect the fluctuation of effective diameter, parallel leaf springs are used to cancel the eccentricity of center and the deformation of ball screw. In this paper, experimental results along the whole length are shown, and cancellation of the affect caused by eccentricity of ball screw shaft is confirmed.
