CryoCut Cryogenic Machining Systems

Cryogenic machining is the application of a small jet of liquid nitrogen (LIN) or a controlled-temperature mixture of LIN and gaseous nitrogen (GAN) to the cutting zone. This process replaces standard flood-cooled or dry cutting operations where improved cutting performance can be realized through low temperature heat management. Temperatures possible with GAN or LIN have a wide range, 32˚F to -321˚F making them suitable in wide ranging machining applications.

Industrial Cryogenic Technologies CryoCut® cryogenic machining uses a small jet of liquid nitrogen (LN₂) or a controlled temperature mixture of LN₂ and gaseous nitrogen to to deploy freezing temperatures to the cutting zone during machining to dramatically altering how heat is generated at the point of cut. Because heat is a primary limiting factor in machining speed, tool life and material integrity, the result is: increased cutting speeds, longer tool life, less machine downtime, improved dimensional accuracy, improved finish quality as machined and improved process reliability without the coolant mess.

• Removes heat from the cutting zone.
• Allows for machining of soft or delicate materials. 
• Reduces the need for secondary deburring.
• Reduces the need for secondary cleaning.
• Enables hard-turning often replacing grinding. 
• Increases the insert’s hardness and toughness by keeping it at cryogenic temperatures.
• Improves surface and substrate hardness, and reduces residual stresses, through quenching of the as-machined surface.
