On the Sharpening of Edged Circular Tools by Electrolytic Polishing (continued)

Abstract

The sharpening method of circular cutleries by electrolytic polishing was discussed in the previous report. The level of electrolytic solutions was kept constant and the resultant shapes of the cross section of the edge were comparatively slender. In this research the relatively slow motion between the level of the solution and the circular discs of the cutleries, that is, the gradual elevation of aqueous level was given by adequate attachments. Then the resultant shape of the polished edge was very desirable, that is a form was thick in the inner side and sharply thin in the peripheral side. This shape coincides with the theoretical estimation.
The details of the experiment are explained and the results are discussed.
