Liquid nitrogen insert cooling extends insert life and allows greater use of low-cost ceramic inserts for hard turning cryogenic machining operations. Cubic boron nitride (CBN) and polycrystalline cubic boron nitride (PCBN) inserts have traditionally been the tools of choice for hard turning applications. However, many shops contemplating hard turning are turned off by their high … Continue reading Cryogenic Machining Drastically Improves Cycle Times
