摘要：
In a method of manufacturing an axis seal, first, a roll of rolled metal material is cut into metal material plates of a predetermined size. Next, metal material plates are etched from both sides so as to form a predetermined size. Subsequently, the thin metal plates are arranged so as to be in a ring shape, oriented in the same direction, and are welded so as to be fixed. Additionally, during these processes, heat treatment is performed by heating rolls of rolled metal materials or metal material plates or thin metal plates at a predetermined timing, thereby eliminating residual stress (strain).
