BSTRACT
The efficiency of micro cutting tools that are used in high-speed air
turbine spindles depends on the rotational speed of the rotor, especially
whe machining medical materials such as titanium alloys. 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 to
support new developments in the developing area of micromachining. A
variety of spindle designs are proposed and numerical simulations carried
