一前言在经济高度发展的情况下,对致力于产品生产的技术人员来说,现阶段的停滞状态,既要检查堆积如山的毫无余地的技术问题,来提高技术水平;另一方面也是考虑为下一步稳定发展作准备的绝好机会。关于冲裁加工,由于生产速度的迅速提高,其注意点将向使用简易模的小批量生产或高精度制件的精密冲裁方向转移。有关精密冲裁加工的名称,读者对瑞士发明的精密冲裁已有所知,在这里,我们将介绍 A foreword In the context of a highly economic development, for those technicians dedicated to the production of products, the current state of stagnation needs to check not only the accumulation of unskilled technical problems, but also the technical level; on the other hand, For the next step in the steady development of a good opportunity to prepare. With regard to blanking, due to the rapid increase in production speed, attention is paid to the precision blanking of small-batch production or high-precision parts using simple molds. The name of precision blanking, the reader of the Swiss invention of precision blanking known, here, we will introduce
