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