Document Type and Number:
WIPO Patent Application WO/2011/068042
Kind Code:
A1
Abstract:
Provided is a method of machining a sealing surface, such that a sealing surface can be finished at low cost and in a short period of time, and such that lead marks can be eliminated and a sealing surface formed with high precision. While a workpiece having sealing surface (M) to be machined is rotated about the axis of the workpiece, the sealing surface (M) is cut and finished with a rotating cutting tool (81). The cutting of the sealing surface (M) by the cutting tool (81) is a type of hardened steel cutting method which generates no lead marks.
