摘　　要：为了提高C/E复合材料构件制孔加工质量,以C/E复合材料为研究对象,提出"以磨代钻"制孔新工艺,并研制了电镀金刚石刀具。与传统硬质合金刀具钻孔工艺进行对比试验,结果表明:金刚石刀具钻削轴向力降低30%-50%、刀具耐用度提高3-5倍、缺陷显著减少,更适合C/E复合材料钻孔加工。Carbon fiber reinforced plastics is one of typical difficult-to-machine materials which will easily bring on disfigurements such as burrs,delamination and avulsion during drilling.In order to improve the drilling quality,the carbon fiber/epoxy（C/E） composite was studied,and a grinding drill and its new process were developed.Some experiments on the grinding tool were carried out.The results show that the thrust force decreases by 30%-50%,the tool life is improved by 3 to 5 times and the disfigurements are minimized compared with the traditional carbide twist drill.
