Using the electrolytic-abrasive mirror-finishing method

large workpieces of ordinary steel and hard process material

for example

stainless and titanium alloy steel

can be easily mirror-finished in a short time and with high efficiency

resuliting in a surface roughness of up to R

0.01-0.02m. This method is based on the fact that the electrolytic effect is assisted by the removel action of abrasive grains within an appropriate current density range by the use of neutral salt-type electrolyties.This paper clarifies the combined effects of the electrolytic dissolution and polishing action of abrasives. It also describes analysis of the surface roughness formation mechanism and the experimental resules.
