  • Abstract This study aimed to investigate the polished characteristics of pure aluminum rod using a conductive polymer tool under different electrolytes and abrasive sizes. Experimental results showed the abrasives adhered on the Al surface for the water as the solvent of the electrolyte, and the acidic electrolyte would corrode the workpiece and tool. They were not suitable for polishing. A neutral organic solution of sodium nitrate-methanol did not injure the polishing of the Al, and it was selected as the electrolyte.
    In the abrasive polishing experiment, the Rmax and Ra values of pure aluminum rod were decreased from 0.40 μm and 0.10 μm to 0.23 μm and 0.057 μm using the electrolyte containing alumina abrasives with the grit size of 1 μm under the load of 0.3 N after polishing for 6 minutes. In the pure electrolysis experiment, the Rmax and Ra values were decreased to 0.33 μm and 0.08 μm under the current of 5 mA under the load of 0.3 N after polishing for 6 minutes. Using the optimum experimental conditions mentioned above, the composite electrolysis abrasive polishing was conducted. The Rmax and Ra values of pure aluminum rod were decreased to 0.19 μm and 0.051 μm for 6 minutes.
    Finally, in order to polish the entire surface of the pure aluminum rod, the axial feed rate of the tool electrode was set to be 9 mm/min. The Rmax and Ra values were decreased to a bright mirror with Rmax 0.21 μm and Ra 0.053 μm under the optimum experimental conditions after polishing for 3 cycles.
