metal raceway workとは 意味・読み方・使い方

To achieve a manufacturing method capable of securing durability of both dies 25a, 25b by suppressing stress occurring in the dies 25a, 25b during work, and exposing a clean metal material to a double-row outer ring raceway existing on an inner peripheral face of an outer ring with short pitches between the rows.例文帳に追加

加工時に金型２５ａ、２５ｂに生じる応力を抑えてこれら両金型２５ａ、２５ｂの耐久性を確保でき、しかも、列間ピッチが短い外輪の内周面に存在する複列の外輪軌道に清浄な金属材料を露出させられる製造方法を実現する。 - 特許庁
