摘要
A method for improving the transient thermal properties of hydrostatic air main spindles for precision machine tools comprises the steps of installing an entire precision machine tool that has a main spindle with an air-lubricated hydrostatic bearing in a temperature- controlled constant-temperature environment, and raising the temperature of the lubricating air supplied to the air-lubricated hydrostatic bearing above the temperature of the constant-temperature environment until the thermal displacement of the main spindle reaches a target value, and thereafter lowering it below the temperature of the constant-temperature environment.
