<p>PROBLEM TO BE SOLVED: To eliminate a trouble that a work is caught with a work table at the time of discharging the work by opening/closing the work table holding the work, adjusting a opening quantity and vertically dropping the work to discharge. SOLUTION: The work is loaded on work tables 6, 6, which are in contact with each other and integrated, and is machined by a laser beam machining head 1. A cavity to transmit the laser beam is formed in the work tables 6. When completing machining, a piston 4 is extended and arms 5, 5 operate in the opening direction. The work tables connected to an end part of the arms 5, 5 rotatable are opened horizontally as well as left/right along a guide rail 7 to form a path. The work is vertically dropped to be discharged. When completing discharge, the piston 4 is retracted to close the arm 5, the work tables 6, 6 are approached/integrated and receives a work to be machined next. A stroke of the piston 4 is adjusted in accordance with a size of the work.</p> |
