Flood coolant might be +70°F. The liquid nitrogen is -321°F—a difference of nearly 400°F. That difference is enough to turn the tool into a heat sink. Rather than using a manufactured fluid for cooling, cryogenic machining simply uses nitrogen, a substance that is taken from the natural air and given back to the air. No fluid

Advancements in cryogenic machining technology use vacuum-jacketed feed lines to deliver small flow rates of liquid nitrogen (LN2) through the machine, through the spindle (or turret) and through the tool, near its cutting edge. At this point, the LN2 evaporates and cools the cutting edge to -321°F. This refrigerated state
