大型挤压模具空刀的阶梯式加工

Machining of Tapper for the Run-Out Large-Scale Extruding Die

阐述了在大型挤压模具中,将模孔空刀部分的加工由全体积电火花加工改为进行部分铣削后再进行电火花加工,即保证了模具的使用效果,又提高了模具的加工效率,降低了加工成本。

Elaborated in run-out machining of the large-scale extruding die, changed all volume EDM machining to EDM machining before partly milling, guaranteed die using effect, raised die＇s processing efficiency, reduced the processing cost.
