Abstract
It is the object of our research whether electrolytic polishing can be applied to the precision finishing of gauges or machine parts. Our experiments were begun with measurement of polishing rate at the different points of the objects which had been polished and had acted as the anode.
First we observed the mean polishing rate at both the fore and back surfaces of the specimen plate which was placed in parallel to the cathodic plate under different conditions.
Secondly we also determined the characteristic polishing rate at the extreme parts of them in case that they were placed perpendicularly to the cathode. Lastly the discussion.were given. In our experiments, there were adopted the special methods in which two identical plates were put together and the side beam of them was kept off the intruding electrolytic liquid by paraffin.
We must add that copper plate was used as the specimen and phosphoric acid as the liquid. The research should be continued in order to so design the form of the cathodic plate as to finish plug gauges precisely.
