日本精密电加工研究所为扩大冲压机业务,开发了大型复合加工油压机。这种机器上装有该所研制的将级进冲压改变成组合简单冲压的结构,所以能获得与级进模相同的加工精度。工作前的准备时间 Japan Precision Electrical Processing Research Institute to expand the business press, the development of large-scale composite processing hydraulic press. This machine is equipped with the developed progressive stamping into a simple combination of stamping structure, it can get the same progressive die progressive machining accuracy.
