1.概述: 精冲工艺为日本高精度机械零件的生产做出了很大贡献。自从二十年前日本引进精冲工艺以来,现已有200多台精冲机投入使用。精冲已成为用金属板材大批量生产精密机械零件的重要工艺;而且这一工艺的重要性正在增大。
1. Overview: Fine blanking process has made great contribution to the production of high-precision mechanical parts in Japan. Since the introduction of fine blanking technology in Japan 20 years ago, more than 200 fine blanking machines have been put into operation. Fine blanking has become an important process for the mass production of precision machined parts from sheet metal; and the importance of this process is increasing.
