Abstract

The paper discusses two topics that the author has found to be of importance in the application of air bearings to diamond tool machine tools. The first topic discussed concerns the potentially poor performance, in relation to a machine tool, of an air bearing journal, if it is designed for the maximum possible static load carrying capacity. The problem is associated with a sometimes self-excited instability, associated with the compressibility of air. The second subject is concerned with two different types of non-influencing drive system , both of which have been used to promote a vibration-free mode of operation. One type of drive provides a uniform linear motion to an air bearing supported table on a diamond tool flycutter. The other type of drive has been used to provide angular velocity to the Headstocks of both a diamond tool lathe and an aspheric generator.
