多孔管、棒挤压模加工工艺的改进

Technology Improvement of Extruding Die for the Multi-Hole Pipe and Rod

采用微调镗刀和专用磨头,在铣床上加工多孔管、棒挤压模工作带,代替了传统的电加工和钳工手工抛光方法,使模具工作带的尺寸精度和表面光洁度得以显著提高。

Multi-hole pipe and rod extrusion die land length can be processed on milling machine by slight adjustment boring tool and special sharpen figure which replace traditional electrical process and manual polishing process of locksmith and the dimension precise and surface roughness get largely improved in die land length.
