摘　　要：随着孔深的增加,孔的直线度将有所下降。针对BTA(Boring and Trepanning Association)深孔钻削中的轴线偏斜问题,从加工方式、导向条布置、长孔钻削三个角度进行研究,分别介绍了三者产生影响的原因,最后通过对切削方式的合理优化,从而得出最佳的钻孔轴向直线度。The straightness of the hole is more critical due to the depth of the hole.In order to solve the problem of axial deviation in BTA（Boring and Trepanning Association） deep holes drilling,this paper reserches the effect of the processing methods,the layout of support pads and long holes drilling on the axial straightness of the deep-holes drilling.Finally,through the rational optimization of cutting method,the best axial hole straightness is obtained.

关 键 词：直线度 加工方式 稳定度 位置角
