Claim 12:
13. A machining system comprising:
a turbine motor spindle assembly;
a live tooling machine or multitasking machine;
the turbine motor spindle assembly including
a drive shaft with a first end and a second end and an outer wall, the first end including an axial bore and a set of openings in the outer wall at a position from the first end, the axial bore in fluid communications with the set of openings, the drive shaft including at least one bearing surface which mates with a first inner ring of a first drive shaft bearing and a second inner ring of a second drive shaft bearing;
a turbine motor housing with a first axial end and a second axial end, at least three internal bores formed along an axial direction between the first axial end to the second axial end, including
a first internal bore of a first diameter size to accept a first outer ring of the first drive shaft bearing,
a second internal bore of a second diameter size to accept a second outer ring of the second drive shaft bearing, and
a third internal bore of a third diameter size to accept a turbine motor assembly thereinto, the turbine motor assembly with at least one turbine in fluid communication with the set of openings of the drive shaft and the turbine motor assembly including one or more tangential openings that expels exhaust air from the at least one turbine; and

a manifold with a second end coupled with the second axial end of the turbine motor housing and a first end coupled with a shank, the manifold includes a fluid inlet in fluid communication with the axial bore of the drive shaft to drive the turbine motor assembly and at least one axial opening in fluid communication with the one or more tangential openings of the turbine motor assembly for air being expelled therefrom.
