Method and apparatus for mixing within a rotary union of a computer numerical control machine a constant pressure gas with a relatively higher-pressure, lower-temperature dense fluid to produce a dense isobaric fluid deliverable through a rotating tool without gelling or solidifying therein. The constant pressure gas may include carbon dioxide, nitrogen, air or mixtures thereof. The dense fluid preferably includes liquid carbon dioxide at or above its triple point. The liquid carbon dioxide and isobaric gas are independently fed to the rotary union. When mixed, a pressurized flowing carbon dioxide machining fluid composition is formed exhibiting a temperature between about 20° F. and 70° F. at pressures between 75 psi and 1,000 psi.
A method of mixing within a rotary union of a computer numerical control machine a dense machining fluid deliverable through a rotating tool without the dense machining fluid solidifying therein, the method comprising the steps of:
