一、前言空气静压技术不仅广泛应用于仪器仪表领域,而且在精密加工中亦越来越发挥出重要的作用。除了业已成熟应用的高速风动磨头和高速牙钻等外,精密机床的主轴、导轨采用空气轴承的也不乏其例。它具有轻便灵活、精密洁净等主要优点。其承载能力和刚性亦能适应精密切削加工的要求。 I. Introduction Air static pressure technology is not only widely used in the field of instrumentation, but also more and more play an important role in precision machining. In addition to the already mature application of high-speed pneumatic grinding head and high-speed dental drill, etc., precision machine tool spindle, guide rail using air bearings are also some examples. It has the main advantages of light and flexible, precision and cleanliness. Its carrying capacity and rigidity can also meet the requirements of precision machining.
