PROBLEM TO BE SOLVED: To provide a small-sized machining apparatus capable of improving working efficiency. SOLUTION: A workpiece feed part B is arranged to one side of a laser beam machining apparatus body A. A workpiece holding part C is arranged to the other side of the laser beam machining apparatus body A. Means, which are for positioning a workpiece w to a machining table 2 in a horizontal state by vertically taking out the workpiece w, are provided to the workpiece feed part B and the workpiece holding part C respectively. A stocker 50, to which the workpiece w is arranged, is arranged to the workpiece feed part B. A stocker 50h, to which the workpiece w is not arranged, is arranged to the workpiece holding part C. The surface side of the workpiece w arranged to the stocker 50 is machined. The machined workpiece w is arranged to the stocker 50h. When the machining of the workpiece arranged to the stocker 50 is finished, the stocker 50h is rotated by 180 degrees around a vertical shaft by a lifter 60. The rear face of the workpiece w is machined by the reverse procedures. When all the machining of the workpiece w is finished, the workpiece w is returned to the stocker 50.
