本文是对 BTA 深孔钻具的轴行为的研究。对于其他切削过程，刀轴的动力学通常被视为二阶集中质量系统的动力学。由于深孔钻削的轴长和液力偶合器的原因，这种简化不适用于深孔钻削。建立了深孔钻管状流体输送工具轴的一般运动方程。所提出的一般方程可以简化为以前作品的不同具体形式。给出了横向和纵向运动的解决方案。设计并进行了一系列实验。理论与实验结果的比较证实了所构建方程的有效性。所公开的研究建立了有关刀轴的知识，并为未来研究刀轴与切削头上发生的切削过程之间的相关性铺平了道路。
This paper is a study on the shaft behavior of BTA deep hole drilling tool. The dynamics of tool shaft are often taken to be that of a second order lumped mass system for other cutting processes. This simplification does not apply for deep hole drilling because of its shaft length and the fact of fluid coupling. This paper constructed the general equations of motion for the pipe-like fluid conveying tool shaft of deep hole drill. The proposed general equations can be reduced to different specific forms of former works. Solutions for lateral and longitudinal motions were given. Series of experiments were designed and performed. Comparisons between theoretical and experimental results confirmed the validity of the constructed equations. The studies disclosed build the knowledge about the tool shaft and pave the way for future research concerning the correlation between the tool shaft and cutting process taking place on the cutting head.
