Polishing with this device is more rapid than with vibratory polishing and results are excellent. Because the bowl is plastic, undesired reactions do not occur during attack polishing. All of the samples shown here were final polished using colloidal silica, also known as Syton, developed by Monsanto. 8 A medium nap synthetic cloth was used to line the Fini-Pol bowl and colloidal silica and distilled water, approximately equal parts, were added to just cover the cloth. Specimens were placed in the holding fixtures and inserted inside the bowl.
Fixtures rotate against rollers while the wheel is slowly rotated.
A rather low speed was used. This should just lightly color it a pale yellow. Too much attack polishing solution produces excessive etching. With a little experience, superb results are obtained. By itself, colloidal silica produces excellent final polishing results for most metals.
