PURPOSE:To smoothly perform the laser beam machining of a tall work by providing the lift platform to load the work via a lift driving means freely ascendably and descendably on the fitting member of a table. CONSTITUTION:A work 16 is loaded on the loading surface 15g of the lift platform 15 of a table 3. When a handle 12 is manually turned in H direction, a main shaft 10a is rotated in H direction together with a sprocket 11a. The lift platform 15 is thus descended in the arrow mark F direction and located at the prescribed position by adjusting this descent position. A torch 6 is adequately moved and located at the position apart by the prescribed distance to the upper part from a work face 16a. The laser light is projected simultaneously from the torch 6 for the work face to work a work 16. The handle 12 is then turned in the opposite direction (G direction) to ascend the lift platform 15 and the work 16 is taken up. In this way, even the working of the tall work 16 exceeding the ordinary movement stroke of a torch can smoothly be performed. |
