摘　　要：高效率磨粒加工是先进制造方法的重要组成部分,集粗精加工与一身,达到可与车、铣和刨削等切削加工方法相媲美的金属磨除率,而且能实现对难磨材料的高性能加工。阐述了高速超高速磨削、快速点磨削、高效深切磨削、缓进给磨削、高速重负荷荒磨以及砂带磨削等高效率磨粒加工技术的国内外的发展及最新研究进展。研究了高效磨削砂轮、主轴及其轴承技术、高效率磨床、磨削液供给技术、砂轮、工件安装定位及安全防护技术以及磨削状态检测及数控技术等实现高效率磨粒加工的关键技术,分析了发展高效率磨粒加工的重要性。High efficiency abrasive machining is one of the important technologies of advanced manufacture. Combined with raw and finishing machining, it can attain high removal rate like turning, milling and planning. The difficult-to-grind materials can also be ground by means of this method with high performance. In the present paper, development status and latest progresses on high efficiency abrasive machining technologies relate to high speed and super-high speed grinding, quick point-grinding, high efficiency deep-cut grinding, creep feed deep grinding, heavy-duty snagging and abrasive belt grinding were summarized. The efficiency and parameters range of these abrasive machining processes were compared. The key technologies of high efficiency abrasive machining, including grinding wheel, spindle and bearing, grinder, coolant supply, installation and orientation of wheel and workpiece and safety defended, as well as intelligent monitor anti NC grinding were investigated. It is concluded that high efficiency abrasive machining is a promising technology in the future.
