Abstract
We already investigated experimentaly the electrical Polishing rate of plate anodes and gave out the results last year. This time electrolytic polishing with respect to cylindrical, ground steel parts was tried. In this case we aimed to succeed in the precision polishing, which was expec-ted to be a practical method of polishing away the required thiCkness layer from the parts which were needed high accuracy and were in the course of mass production.
The temperatures at 5 points in the solution were measured and the mean temperature of those was calld "bath temperature" by the writers.
First 30minutes polishing was carried out with constant current that was regulated easily by the resistance.
The relation between the polished away quantities and the bath temperatures was plotted on the graph.
Secondly the parts were polished for 30minutes with the same current, and the temperature changes of the bath were measured in several cases where the starting temperature was different respectively. The relation between the bath temperature and the time was graphically plotted.
By using the upper two graphs the precision finishing that we aimed at could be done. The experimental data were shown and discussed.
