Abstract

PURPOSE: To provide constant values of voltage-current characteristics and avoid the generation of an abrasion by forming a feeder element of a material having hardness higher than a workpiece and contacting the workpiece with 50gW150g of a press force.
CONSTITUTION: An aluminum alloy disk-like workpiece 11 is pinched rotatably by a plurality of rotary drive resin rollers 10 and contacts rotatably an electrode (negative pole) tool 12 with about 1kg/cm2 of press force. Electrolyte is supplied from the polished surface while about 3 volt of DC voltage is supplied from a feeder element 13 for electrolytic polishing. This feeder element 13 is formed of quenched steel having hardness higher than the workpiece 11, for example Hv 600 of hardness, 0.2μmRmax of surface roughness and 6g/cm2 of spring constant and contacts the peripheral end edge of workpiece 11 with 50W150g, preferably 70W90g of press force by a feeder element support 14. Thus, voltage- current characteristics in the feeding spot will have constant stable values and so abrasions occur in carring out surface polishing.
