微靶柱腔半圆形诊断孔加工技术

The Technique for Machining a Pair of Hemiroundness Diagnosis Hole on a Cylindric Hohlraum of Micro Targets

采用微细电火花两次成形加工法,在带有宽度50μm微槽的柱腔上加工出一对半圆诊断孔,经后续手段对接后成为一个完整的圆形诊断孔。介绍了半圆诊断孔的加工工艺以及优化的加工参数。

Adopting twice forming method of micro EDM, a pair of hemiroundness diagnosis hole on a cylindric hohlraum with a micro groove of 50um in the width was fabricated, then they were made up to turn them into a intergrated round diagnosis hole by succession means. The technique to machine a pair of hemiroundness diagnosis hole was introduced, and the parameters were optimized in the paper.
