提出了一种用于微铣削应用的创新型气动主轴，其中使用所谓的粘性涡轮来驱动和支撑主轴。粘性涡轮通过直接在主轴的光滑表面上施加粘性牵引力来驱动主轴。甚至可以直接使用标准铣刀作为主轴，从而使具有固有不准确性的刀架变得多余。此外，粘性涡轮不仅驱动工具，而且还充当空气静压径向轴承。本文提出了粘性涡轮机概念，并使用简化的分析模型对相关设计尺寸进行了优化。提出了原型主轴设计，分析了第一个实验的结果，并提出了对第二个原型的改进。
An innovative air driven spindle for micro-milling applications is presented, in which a so-called viscous turbine is used to both drive and support the spindle. The viscous turbine drives the spindle by exerting viscous traction forces directly on the smooth surface of the spindle. It is even possible to use a standard milling tool directly as spindle, thereby rendering a tool holder, with its inherent inaccuracies, redundant. Furthermore the viscous turbine not only drives the tool, but also functions as an aerostatic radial bearing. In this paper the viscous turbine concept is presented, and an optimisation for the pertinent design dimensions is carried out using a simplified analytical model. A prototype spindle design is presented, and the results of the first experiments are analysed and improvements for the second prototype are proposed.
