In recent years, the applications of fine blanked parts are being gradually expanded with the rapid development of the fine blanking technology at home and abroad. Especially in auto industry, more and more parts are required to be produced by fine blanking technology with the improvement of quality. It is necessary to update the previous technology standards to adapt the development of fine blanking technology. Based on the considering of the fine blanked parts tolerance, cut surface quality, die roll and the geometric shape, two technology standards of fine blanked parts were amended. The foreign fine blanking specification was used as amending reference and the current situation and tendency of fine blanking technology in China were considered.
