  • Liquid Nitrogen an Alternative to Traditional Coolants

    2018-5-30 · Cryogenics offer an alternative to traditional liquid coolants when conventional cooling methods can't or don't do the job well enough. For example the Cryogenic System from 5ME LLC (Cincinnati) moves liquid nitrogen (LN2) through the machine spindle and cutting tool to just behind the cutting edges. This approach yields a cutting tool refrigerated to −321°F (−196°C).
