しかし、帯状の薄板を打ち抜くとき、千鳥状に円板を打
ち抜いても、円板を打ち抜いた後の材料の残り、つまり
スクラップが多く廃山されるため歩溜りが悪く、材料の
使用率が低くて製造コストが高くなるという問題点を有
していた。However, when punching out strip-shaped thin plates, even if the disks are punched in a staggered pattern, a lot of the material remaining after the disks are punched out, that is, scrap, is discarded, resulting in poor yields and a low material usage rate. However, there was a problem in that the manufacturing cost was high.
また、絞り加工のときの変形率が高いため、カバーに割

率が高すぎてカバーの表面が荒くなり、仕上げ、研磨加
工が必要とし、さらに材料の厚みも薄材に制約される問
題点も有していた。In addition, since the deformation rate during drawing is high, it is easy to produce defective products with cracks and wrinkles on the cover.Furthermore, the drawing rate is too high, making the surface of the cover rough, making finishing and polishing difficult. Moreover, there was also the problem that the thickness of the material was limited to a thin material.
