Abstract

An apparatus and method for machining a superhard substrate comprising: a means for pre-cooling a non-aqueous cutting fluid at a temperature below 20 degrees C. and at atmospheric pressure to form a subcooled cutting fluid; a capillary tube injector, which saturates said subcooled cutting fluid with the solid and gas carbon dioxide; an inline static mixer for combining said subcooled cutting fluid and said solid and gas carbon dioxide; a spray application tool for applying said carbon dioxide saturated subcooled cutting fluid to the superhard substrate during a machining process; and a recovering apparatus for collecting said residual cutting fluid from the machined superhard substrate; said recovering apparatus can comprise a carbon dioxide spray cleaning, a liquid carbon dioxide immersion cleaning, or a supercritical carbon dioxide cleaning.
