A typical spindle system is fundamentally constructed by a spindle, bearings for supporting the spindle, a driving system for driving the spindle rotation, a cooling system for circulating fluids, and spindle housing for supporting the spindle and the bearings, etc. The rotational speed, power, torque, dynamic stiffness, and thermal properties of the spindle system determine the machining accuracy and productivity of the machining process. An air turbine–driven aerostatic spindle system provides high speed and precision spindle rotation in a noncontact condition. The air turbine has 2D spiral grooves from the rotational center and provides the rotational torque without ripple by supplying air from the spindle center. Therefore, the spindle system is one of the most effective spindle systems for micro- and nanometer scale processing.
