Syntron vibratory polishers (two identical pieces)
Vibratory polishing is an effective final polishing technique that is widely used with metals that are difficult to polish. The vibrations in both vertical and horizontal directions produced by electromagnetic forces induce the sample to move about its axis and around the cloth periphery. The vibration amplitude is adjusted to a level just adequate to produce smooth movement around the bowl. The gentle polishing greatly reduced the surface residual stress and strain.
