Description
次に、第3の実施形態による横型旋盤3の実施例について説明する。第1実施例として、吸収側チャック爪36における少なくともターゲットロッド50との接触部分を構成する摩擦係数が低い材質として軟鋼を用いる。図4は、横型旋盤3の吸収側チャック爪36に軟鋼を用いた第1実施例における、ワーク加圧力に対するターゲットロッド50の振幅を示すグラフである。また、第2実施例として、吸収側チャック爪36における少なくともターゲットロッド50との接触部分を構成する摩擦係数が低い材質としてフッ素樹脂を用いる。図5は、横型旋盤3の吸収側チャック爪36にフッ素樹脂を用いた第2実施例における、ワーク加圧力に対するターゲットロッド50の振幅を示すグラフである。ここで、ターゲットロッド50は、石英ガラスからなる。図6は、ターゲットロッド50の振幅を説明するための略線図である。図6に示すように、ターゲットロッド50の振幅とは、図6(a)に示すターゲットロッド50が回転軸Oに平行な通常状態に比して、図6(b)に示すターゲットロッド50が回転軸Oに対して外側にたわんだ、いわゆる振れ回りの状態における最大変位(mm)を意味する。
