Multi-objective Optimization of Machine Tool Spindle

Aug 10, 2020· Low friction bearings reduce the heat generation in the spindle, thus suppressing the rise in operating temperature. This eventually improves the machining accuracy of the machine tool. Therefore, a reasonable value for the bearing preload must be selected to resolve the tradeoff among the design goals that address the friction torque, natural

Aerostatic Bearing - an overview | ScienceDirect Topics

Frank Wardle, in Ultra-Precision Bearings, 2015. 4.1 Introduction. Aerostatic bearings rely on an external source of high pressure gas, normally air, to generate load carrying capacity. In the vast majority of aerostatic bearing appliions, the gas is compressed air sourced from a factory air line for which delivery pressures are typically 5 to 6 Bar. . This is a relatively low pressure to
