孔径小于材料厚度的小孔加工是相当复杂的工艺课题。 无线电电子技术及控制仪表的发展、要求建立小孔(孔径达0.1mm甚致更小)的加工方法,现在,最有效的方法是电加工。 本文研究采用冲压工艺制取小孔的方法。使用普通冲孔模冲制孔径小于材料厚度的小孔是很困难的。因为如此细小的冲头将
Hole diameter is smaller than the thickness of the material processing is a very complex process topics. The development of radio electronic technology and control instrumentation requires the fabrication of small holes (very small 0.1 mm in diameter). Now, the most effective method is electric machining. This paper studies the stamping process for making small holes. It is very difficult to punch a hole with a hole diameter smaller than the material thickness using a common punching die. Because of this small punch will be
