る。According to the die cutter manufacturing method of the present invention, it is possible to form a blade made of cemented carbide on the roll surface, which has not been considered as conventional technical knowledge. In other words, according to conventional technical knowledge, it is difficult or impossible to form a blade or machine a cemented carbide, so even though we know that the cemented carbide itself has high hardness, we cannot use it as a blade material. This was something that no one in the industry had thought about.

Polishing was possible. In this manner, the present invention was able to establish mass production technology for die cutters equipped with cemented carbide blades for the first time by combining high-density energy fusion and electrical discharge machining.
