A self-developed cryogenic machine tool with conveying liquid nitrogen through the spindle and tool was specially used to carry out milling experiments. The results indicated that the nitrogen phase had a most significant effect on surface roughness, followed by the pressure while the effect of flowrate was lowest.
Cryogenic Milling is a process to reduce particles by means of mechanical force as well as embrittlement of the material by means of cooling by liquid nitrogen. Thus, the fracture behaviour of viscous or elastic materials is transferred into the state that a grinding/ milling is possible.

Cryo Milling Process What is Cryogenic Milling? Cryogenic milling, or cryo-milling, is the process of using liquid nitrogen to lower the temperate of the material and/or the milling process. AVEKA 's cryogenic hammer mills can typically reduce the particle size from small pellets down to the 100s of microns. Cryo-milling can be used for:
SPEX Europe's Freezer/Mill® is a programmable cryogenic mill specifically designed for grinding and pulverizing tough or temperature sensitive samples..

Cryogenic grinding, also known as freezer milling, freezer grinding, and cryomilling, is the act of cooling or chilling a material and then reducing it into a small particle size.For example, thermoplastics are difficult to grind to small particle sizes at ambient temperatures because they soften, adhere in lumpy masses and clog screens. When chilled by dry ice, liquid carbon …
The results obtained showed that both cryogenic and MQL machining showed improved performance in comparison to the dry and wet machining. For cryogenic machining, however, the exposure to LN2 causes the thermal gradient on the cutting tools and the hardening of the titanium alloy during the machining, which resulted in excessive tool wear and ...
