GRIPPING TOOL FOR CENTERLESS GRINDING, METHOD OF MANUFACTURING RESIN SEAL RING USING THE SAME, AND RESIN SEAL RING MANUFACTURED BY THE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a resin seal ring having a highly accurate dimension superior in sealability, without increasing manhours in manufacture.

SOLUTION: A plurality of annular ring-shaped endless resin seal rings (3') are inserted into a cylindrical gripping tool (30), and are arranged in a centerless grinding machine (40), and an ended resin seal ring (3) having the highly accurate dimension can be manufactured by polishing an outer peripheral surface (3b) of the seal rings (3'). Processing labor by shaving-out is omitted, and processing cost is reduced.
