It features an integrated cooling system which continually cools the grinding jar with liquid nitrogen before and during the grinding process. Thus, the sample is embrittled and volatile components are preserved. The liquid nitrogen is continually supplied from an autofill system in the exact amount required to keep the temperature at –196 °C.

Hydrodynamic grinding is driven by hydraulic pressure so that the liquid medium carrying abrasive grains flows back and forth across the workpiece surface at high speed. The medium is mainly made of special compounds (polymer-like substances) that flow through under low pressure and mixed with abrasives. The abrasives can be silicon carbide powder.

Quenching is a rapid way of bringing metal back to room temperature after heat treatment to prevent the cooling process from dramatically changing the metal's microstructure. Metalworkers do this by placing the hot metal into a liquid or sometimes forced air. The choice of liquid or the forced air is referred to as the medium.

Foam is a stable dispersion of a gas in a liquid medium that results when a surfactant layer forms around air bubbles and entrains them within it. Air can be incorporated into a coating by: Mixing during the polymer/pigment grinding and let-down steps. Pumping during package filling. Shear or spraying during application.

In centerless grinding, the workpiece is held between two grinding wheels, rotating in the same direction at different speeds.One grinding wheel is on a fixed axis and rotates so that the force applied to the workpiece is directed downward. This wheel usually performs the grinding action by having a higher linear speed than the workpiece at the point of contact.
