采用一冲程微冲深拉深工艺大批量生产外径为1mm的微杯（200冲程/分钟）。切割和拉深用一个空心冲床。外径冲孔圆坯，内径拉拔环。关于刀具寿命的调查表明，冲孔边比刀具的其他部分磨损得更快。此外，还表明刀具的定位对磨损行为有很大的影响。(c) 2014 cirp。
A one stroke micro blanking and deep drawing process is used to produce micro cups in a high quantity (200 strokes per minute) with an outer diameter of 1 mm. For cutting and deep drawing one single hollow punch is used. The outer diameter punches the circular blank while the inner diameter serves-as drawing ring. Investigations regarding the tool life show that the punching edge wears out quicker than the rest of the tool. Furthermore it is shown that the positioning of the tool has a high influence on the wear behaviour. (C) 2014 CIRP.
