Electrolytic in-process dressing
||In this study, a self-developed conductive polymer tool with electrolytic in-process dressing is used to improve the loading problem usually happened on the polishing process of aluminum rod. The influences of electropolishing variables on the surface roughness of aluminum rod, such as the polishing time (0~20 min), the current (10~100 mA) and the dressing voltage (5 V) are investigated.|
The conductive polymer ESD 410C is feasible to employ as an electrolytic in-process dressing tool through the leading experiment. The loading problem occurred on the tool surface during the polishing process of aluminum rod can be significantly removed under a constant voltage of 5 V and a polishing time of one minute. For the electropolishing of aluminum rod under a constant current without tool feeding, the effect of current on the improvement on the surface roughness of aluminum rod shows that it decreases to a saturation value under a current of 70 mA, a load of 0.15 N and 12 minutes. However, its surface roughness rises again after 12 minutes because of the loading problem.
Finally, an electropolishing with simultaneously electrolytic dressing is conducted to polish the aluminum rod. Significantly processing effect can be obtained after 4 minutes, and its surface roughness decreases to a saturation value. Its surface roughness remains to a saturation value even after 20 minutes. This confirms that using conductive polymer tool with simultaneously electrolytic dressing is effective to polish the aluminum rod.
