The effects of cryogenic cooling on the grinding .

01.08.2020 · Hence, the lower grinding forces at the cutting speed of 5 m/s, when utilizing cryogenic cooling, maybe due to less ductile behavior (which leads to less rubbing and plowing regimes) of the workpiece material at lower temperatures. The strength of a polymer is strongly dependent on the temperature. Their strength decreases as the temperature rises and reaches a certain value. This .

CRYOGENIC GRINDING AND IT'S APPLICATIONS · PDF-bestand

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.
