PURPOSE:To perform the travel cutting of the material having various curvature such as the bending of a steel pipe or a steel member, by means of single cutting machine through simple operation for replacing the curvature guideboard. CONSTITUTION:Various curvature guideboard 40 provided with a guide groove 41 where the curvature of the material to be cut is matched are prepared. When the guideboard is fitted in a fitting groove provided between the rails on a base, various bending member can be cut as required by means of single cutting machine only through such work as replacing the curvature guideboard 40 sequentially while matching with the curvature of the member to be cut. When making the groove in the curvature guideboard linear, it may be used as the conventional travel cutting machine. A well known dieset truck may be employed in the travel cutting machine. |
