摘　　要：由于组成材料的性能差异较大,轻质复合构件(陶瓷/玻璃纤维增强复合材料/铝合金)的钻孔加工非常困难。针对构件组成材料的性能特点和破坏方式,研究了金刚石磨料对构件进行套料钻孔的机理,研制特定的钻孔工具和工艺装置,对构件钻削区及其周围材料施加预压应力。试验结果表明:孔口平整,有效避免了构件材料的分层、拉毛和崩豁等加工缺陷。该加工技术成本较低、效率较高,质量较好,并得到了初步的应用。For the great property differences of the compositive materials, the light composite component （ceramic/ glass fibre reinforced composite/ aluminium alloy） is very difficult to bore. In view of the differences in material property and fracture mode, the mechanism of using diamond polish to bore in component is studied, and a special diamond core boring bit is developed. The technological equipment can exert compressive pre-stress on drilling area and surrounding material. The test indicates that the hole is unruffled and that the delamination, napping and breakup can be avoided. The processing technique is of low cost, high efficiency, and excellent quality.
