Polycrystalline diamond is most efficient when used for the initial application of several diamond beads/extenders for pad wetting. Notice that the pad saturation is not necessary. Neither is it recommended. Additional dispensing is typically dripped on the surface at 1 to 2 drops per 10 to 15 seconds, depending on the speed of polishing and the sample?s surface area.

For the preparation of mineral and ceramic specimens, the recommendation is the alternate dispensing of diamond and colloidal silica (or SIAMAT colloidal silica). This results to a chemo-mechanical polishing (or CMP) action that considerably improves removal rates, lowers subsurface damage, and makes the surface finish better.

The technique is ideal for use with 6 micron diamonds and other smaller polycrystalline diamonds. For best results for the application, it is recommended to clean the samples and the cloth during the cycle?s final 15 seconds. Allow running water to flow on the surface of the polishing pad.
