Background

With the improvement of the processing level of the stamping industry, the types and shapes of hardware products tend to be diversified. Further, in order to meet the assembly requirements, a plurality of surfaces or corners of many hardware products (i.e., the bevel on the sheet metal member) need to be tapped.
