本文综述了国内外非导电材料的电加工技术的现状、特点和机理，分析了目前最常见的非导电材料的电加工方法──电解电火花复合加工方法效率低等的原因，并提出了以物理、化学的方式形成电解液火花放电所需非导电相的新加工技术，用此技术可高效地加工非导电脆硬材料的较大表面和较深的孔。 In this paper, the current situation, characteristics and mechanism of electrical processing technology of non-conductive materials at home and abroad are reviewed. The most common method of electrical processing of non-conductive materials ─ ─ - EDM composite machining method is low efficiency, Physically and chemically, a new processing technique for forming the non-conductive phase required for spark discharge of an electrolyte can be used to efficiently process the larger surfaces and deeper pores of a non-conductive, brittle, hard material.
