<p>PROBLEM TO BE SOLVED: To improve the precision of punching working by collecting spatters entered on the turret side during laser beam working to prevent the spatters from attaching to the rear of a formed work. SOLUTION: By forming a groove 23 for collecting dust on the turret, and by rotating the turret preliminarily, the groove 23 for collecting dust is moved to a nearest position to a working head 9. At the time of laser beam working, the turret side and the dust collector side are ventilated through the groove 23 for collecting dust, and the spatters entered on the turret side are collected by the dust collector.</p> |
