Title:
HOLLOW ROTATING SHAFT-FINISHING METHOD AND HOLLOW ROTATING SHAFT
Document Type and Number:
WIPO Patent Application WO/2016/039018
Kind Code:
A1
Abstract:
When cutting the outer circumference (10o) of a hollow rotating shaft (10) along the axial direction using a finishing cutting tool (36), the present invention is designed to further improve the reliability of the hollow rotating shaft (10) at high rotation speed by adjusting the position of the finishing cutting tool (36) in a direction that is orthogonal to a virtual standard shaft center (VS) so that the center position (CPo) of the outer circumference (10o) of the hollow rotating shaft (10) is decentered in the same direction as the direction of a decentering vector (∆Di) with respect to the virtual standard shaft center (VS) and by an amount corresponding to the magnitude |∆Di| of the decentering vector (∆Di) to bring imbalance even at the center of the shaft closer to zero and adequately limit deflection of the hollow rotating shaft (10) even if the rotation speed of the hollow rotating shaft (10) increases.
