PURPOSE:To enable application of a high-precise bead finish work on a weld angle joint part, by a method wherein the slide groove of a weld angled joint part is formed in the inner side of a cross part between the horizontal surface of a machining table and a vertical wall surface, and a rotary cut blade is disposed through the through-hole of the vertical wall surface. CONSTITUTION:With a cut blade 5 rotated with the aid of a motor, a weld angled joint part 10 of workpiece 8 is brought into contact with a groove part 9 of a machining table 2, and a horizontal part 17 of the workpiece 8 is pressed against a horizontal plane part 6 of the machining table 2. The workpiece 8 is then moved in the direction of an opening part 15, where the cut blade 5 is rotated, along the groove part 9, and when the workpiece 8 is moved to the opening part 15, the projected part of the weld angled joint part 10 is cut through rotation of the cut blade 5. In this case, since the upper surface of the cut blade 5 is coincided with the horizontal plane part 6 of the machining table 2, the weld angle joint part 10 is cut horizontally. Further, since a base part 16 of the cut blade 5 is curved, the corner of the weld angled joint part 10 is cut in a shape to be smoothly curved, and by cutting the whole of the joint part 10 through slide of the workpiece 8, a finish work is completed. |
