Mist jet cooling of grinding processes - ScienceDirect

Experiments were performed on a standard Jones and Shipman 540P surface grinding machine. The wheel rotates at 3000 rpm and, with a total wheelhead power of 3.5 kW, wheel speed can be maintained constant over all the depths of cut used here. The speed of the grinding wheel was checked from time to time using an optical tachometer.

Cryogenic grinding - Wikipedia

The idea behind using a solenoid is that the only "moving part" in the system is the grinding media inside the vial. The reason for this is that at liquid nitrogen temperatures (–196°C) any moving part will come under huge stress leading to potentially poor reliability. Cryogenic milling using a solenoid has been used for over 50 years and ...
