。Conventionally, as a processing method of this kind, for example, as shown in the first diagram, a workpiece c having a type having shaft portions a, a at both ends in the length direction and a large thin portion b in the middle thereof is prepared by die-casting, There are known methods in which this is then cut using a lathe or other means, but in this case, the cutting is carried out by supporting the workpiece c from both outside sides with support shafts d and d, as shown in the diagram. In such a case, since the thin part b is more or less weak during the cutting process, the entire part is more or less deformed, which tends to cause a problem in the machining accuracy.

る。In order to eliminate the inconvenience caused by conventional methods, a method is known in which a special holder is fixed to the thin wall part b during the cutting process to reinforce it. In addition, when the holder is fixed by tightening, there are disadvantages such as distortion due to uneven tightening force. The object of the present invention is to provide a method that does not have such inconveniences, and is a method in which a workpiece having a thinner part in the middle part in the longitudinal direction is die-cast and then cut using a lathe or other means. The invention is characterized in that reinforcing ribs are integrally formed in the thin wall portion during the die-casting of the workpiece, and the ribs are removed after the cutting process.

足りて作業は簡単である等の効果を有する。An example of implementing the present invention will be explained with reference to the attached drawings. FIGS. 2 and 3 show one example of this. A workpiece 1 has a shape having shaft parts 2, 2 at both ends in the length direction and a thickened thin part 3 in the middle part thereof. is prepared by cast molding and then subjected to cutting using a lathe or other means. During this cutting, the work 1 is pivotally supported from both outside sides as described above, and in preparation for this. The thin portion 3 is provided with a reinforcing rib 4 substantially along the length direction. To explain this in detail, the thin part 3 has a sparrow-like shape with one side open, and the reinforcing rib 4 extends within the open side at a more or less oblique angle with respect to the length direction.
This is formed integrally with the workpiece 1 during the die-cast molding described above, and then the workpiece 1 is cut as it is. Upon completion of the cutting process, the rib 4 is removed from the workpiece 1. shall be obtained in the product. In this way, according to the present invention, reinforcing ribs are integrally formed on the thin wall portion of the workpiece during die-casting, and then cutting is performed as is. The ribs are reinforced so that there is no problem with machining accuracy, and the ribs only need to be removed in the next step, making the work simple.
