Document Type and Number:
Japanese Patent JP6509348
Kind Code:
B2
Abstract:
Provided are a cylindrical member machining method and machining apparatus that are capable of improving dimensional precision even when machining a cylindrical workpiece with low circularity. A cylindrical member machining method comprises a machining step for machining the outer circumference of a cylindrical workpiece using a support for supporting the cylindrical workpiece by abutting multiple tabs against the inner circumferential surface of the cylindrical workpiece and displacing the tabs outward in the radial direction, and rotating the support on the same axis as the cylindrical workpiece. The machining method comprises a determination step for determining the amount of radial displacement for each of the multiple tabs, and an adjustment step for displacing each of the multiple tabs on the basis of the determinations in the determination step.
