This paper describes examples of ultra high speed machining by aero-static bearing spindle, so called the air spindle. Air spindle has no metal contact, therefore there is no limitation to turn it for long hours in constant at maximum speed. In addition run out of the spindle (NRRO) is smaller than 0.07μm and then tool life can be extended. Due to the above-mentioned feature, air spindle realizes an actual ultra high speed machining only by using small size cutters.
