Cryogenic grinding - Wikipedia

Cryogenic grinding of plant and animal tissue is a technique used by microbiologists. Samples that require extraction of nucleic acids must be kept at −80 °C or lower during the entire extraction process. For samples that are soft or flexible at room temperature, cryogenic grinding may be the only viable technique for processing samples.

CRYOGENIC GRINDING AND IT’S APPLICATIONS

ADVANTAGES OF CRYOGENIC GRINDING Higher material removal rate can be achieved. Tool wear and tear is minimized to a great extent. Grinding forces are reduced. Cryogens act as coolant and hence the effects of overheating of the tool and piece are reduced. Materials which are soft and elastic in nature such as rubber can be easily machined with this process.
