There are provided a base framepositioned below a horizontal axis O; a pair of clamp unitspositioned at the two ends above the base frame; a pair of support unitsthat horizontally support the long workpiece in two locations, and that are capable of moving vertically; and machining unitsthat are capable of machining the long workpiece. The two clamp unitsare capable of moving from the outside toward the inside, which support the long workpiece in two locations, and rotate around the horizontal axis O in synchronization with each other.

Apparatus and method for machining long workpiece

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).
