Cryogenic Machining


Cryogenic machining is the machining of components in the presence of a cryogenic fluid.  Cryogenic fluid is used instead of the cooling liquid at the machining surface.  Liquid nitrogen is delivered to the cutting edge of the tool.  This increases the speed of the machining.  More parts can be machined in the same time.

Conventional machining causes high temperatures.  These high temperatures create thermal stress on the tool and can decrease its life.  Cryogenic machining extends the life of the tool as high temperatures are avoided.

Cryogenic machining is cleaner than conventional machining.  Burr formation is greatly reduced.  Residual stress is also lessened.

Cryogenic machining can be retrofitted in normal machining equipment.
