Popis:	The efficiency of microcutting tools that are used in high-speed air turbine spindles depends on the rotational speed of the rotor. A high-pressure variation on the surface of the rotor causes the rotor to retard and this severely limits the reliability and durability of High-Speed Spindles (HSSs) to support new developments in the developing area of micromachining. A variety of spindle designs were proposed and numerical simulations were carried out for each design using CFX software. The results revealed that changes in the rotor, inlet and outlet geometries affect the pressure distribution on the rotor significantly. The optimum design was identified based on the lowest pressure variation on the rotor surface obtained from the CFX results. Spinning the rotor at very high speeds provides a new direction in the development of mechanical micromachining.
