The solids in the particle dispersion type functional fluid have been found to reciprocate between electrode under AC field at low frequencies. This promotes the continued dispersion of the solids. Here, we have tested the positive use of this phenomenon in finishing process and have found that the process is assisted positively or negatively depending on the strength of applied electric field and the pressure applied to the finishing pad. The optimum electric field strength and pressure are 3.5 kV/mm and 24 kPa.
