Vibratory polishing

Zeiss [48] describes a method for measuring sections of milled ferrite powder. The powder was mixed in 40 60 volume ratios with epoxy resin using a homogenizing head rotating at 25,000 rpm. The mixture was then poured into a 0.5 in diameter mold and cured at 60°C and 1000 psi to eliminate air bubbles. The casting was then polished in a vibratory polisher using 0.3 and 0.5 pm alumina in water. A photomicrograph of the polished section was used for subsequent analysis. 

Use in vibratory polisher, especially with soft materials. 

Fluidized bed A body of powder that is kept in motion by a flow of gas and/or vibration. Particles immersed in the bed can be coated or polished. See also Pack cementation Vibratory polishing.
