CRYOGENICS Grinding Cryogenics Thermodynamics

CRYOGENIC GRINDING PROCESS 1. Cryogenic grinding , also known as freezer milling/ freezer grinding/ cryomilling is the act of cooling or chilling a material and then reducing it to smaller particle size. 2. Almost all materials embrittle when exposed to low temperature.

CRYOGENIC GRINDING AND IT’S APPLICATIONS

ADVANTES 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 work piece are reduced. Materials which are soft and elastic in nature such as rubber can be easily machined with this process.
