摘要
从线切割加工黄铜存在的主要问题：切割颗粒大,电蚀物粘附钼丝,表面粗糙度差,特别是加工薄件时问题尤为突出,从乳化液pH值进行切割实验,经过不同pH值切割实验对比,实验证明pH值在8.80~8.41之间时电蚀物粘附钼丝改善明显,此时表面粗糙度有所改善。从而得出结论：切割黄铜薄件与乳化液pH值相关。此结论不仅对加工黄铜具有前所未有的改善,对加工有色金属具有非常重要的意义。
From the main problems of WEDM processing brass ： cutting particles is large, electrical erosion adheres on molybdenum wire, surface roughness is bad, especially when processing thin plate problem is partic- ularly prominent, from emulsion pH cutting experiments, through different pH cutting experiment con- trast, experiments show pH value between 8.41 -8.80 electric erosion adhering on molybdenum wire improves, meanwhile the surface roughness improves. Thus draw the conclusion： brass thin cutting is as- sociated with emulsion pH value. This conclusion not only has unprecedented improvement on processing brass, but also has importance for processing non -ferrous.
