摘　　要：深孔钻削加工由于其特殊性,是比较难以实现的。通过BTA系统工作原理的分析,从角度、结构、材料上对BTA刀具进行了研究,提出了控制深孔钻削断屑的有效措施。试验证明,这些有效措施可以达到较高的尺寸精度和较低的表面粗糙度,对实际深孔加工具有一定参考价值。It is very difficult to realize the deep hole drilling process because of its specialty. Through the analysis of the operating principle of BTA system, the BAT cutting tools from different angels, construction and materials have been discussed and effective ways to control the discontinuous chips of deep hole been brought out. Experiments have proved that -level roughness which has provided reference drilling have such ways can meet high - level dimensional accuracy and low for oractical deen hole drilling,_
