High speed punch has great advantages in precision stamping of metal coil. However, its premise is to have the right material. If the hardness of the material is very high, but still does not produce tearing; at the same time, the wear of the mold is small, such a material is most suitable.
As we all know, precision punch can use one or two stamping processes to make mechanical parts with good cutting surface finish and dimensional accuracy, which greatly shortens the process and reduces the cost, so it is being popularized. From the perspective of the development process of precision punch, it was popularized to obtain high-precision mechanical parts, that is, high-efficiency production, electronic instruments, communication equipment and other precision mechanical parts.
