- Cryogenics is the study of the
production and behaviour of materials at very low temperatures
- Gas to be cryogenic if it can be
liquefied at or below −150 °C (123.15 K; −238.00 °F).
- Common cryogenics are helium,
hydrogen, neon, nitrogen, oxygen, argon, krypton, xenon, methane,
ethane, and propane
- Nitrogen is a safe, non-combustible,
and non-corrosive gas which accounts to 78% of air we breathe
- Cryogenic cooling is used for the
cooling and lubricating the work piece while machining.
- Dry machining is more sustainable
process than machining with cutting fluid because of absence of
lubricants and coolants
- The cryogenic fluid used is generally
nitrogen fluid.
- When nitrogen delivered to the cutting
region it immediately turn into vapour state and returns back to
the atmosphere, leaving no residue to damage the part, machine tool,
chips, or operator
- Multi-patented cryogenic machining
process enables higher cutting speeds, increased material removal
rates, and longer tool life by transmitting liquid nitrogen at
-321°F through the spindle turret and tool body, directly to the
cutting tool’s edge
- Cryogenic cooling has been shown to
increase tool life significantly through a reduction of tool
temperature near the work piece-tool interface, thereby increasing
the hardness and toughness of the insert.
- Applications for cryogenic machining
include high-speed cutting of titanium and other tough-to-cut alloys
common in aerospace, heavy equipment and energy part processing
- Cryogenic machining allows to obtain
surface roughness parameters
values smaller than during conventional machining
- Cryogenic coolant exhibits promising
improvements in tool life
- Cryogenic cooling is not a cheap
method and also requires the use of specially-designed machine tools
- In India, significant growth of man
power and facility has taken place in this exciting area of
cryogenics and superconductivity
