Cryogenics beats the heat of milling exotic material

Machining exotic materials creates heat--a lot of heat that is detrimental to tool life, demands a slower removal rate, and creates a heat-affected zone (HAZ) on the material that often requires a downstream removal process. Cryogenic metal removal, in development for several years, has reached the point where it can efficiently reduce the temperature at the cutting edge to eliminate those issues. The process can be paired with just about any mill to extend tool life, speed machining, and all but eliminate HAZ and white layers.
