<p>PROBLEM TO BE SOLVED: To provide a laser beam machine that is easy in a setup operation and that excels in machining precision. SOLUTION: The upper center part of a clamp frame 31 is cut out to form an upper face 31a in a picture frame shape, with a workpiece 1 placed on it. Then, in this state, namely, in a state without imparting tension to the workpiece 1, it is fixed on the upper face 31a by means of clampers 33, 40. In machining, the outside in the horizontal direction of a machining area is supported from the bottom by a workpiece receiver 51, with the workpiece 1 held level.</p> |
