Abstract
There is a workpiece clamp device for horizontally holding a thin section long workpiece having a constant section shape or having the same section shape in spaced positions in a longitudinal direction in two positions of the same section shape. The workpiece clamp device is constituted of a driving clamp device A and a driven clamp device B comprising the same holding device . The driving clamp device A rotates the workpiece centering on a horizontal axis O extending in a longitudinal direction of the workpiece, and the driven clamp device B follows movement of the workpiece and idles centering on the horizontal axis. An arbitrary portion to be machined of the workpiece can be directed in a direction in which the portion is easily machined by the rotation (e.g., upward direction).
