Experimental Investigation on Hard Alloy Ring Electrochemical Plane Grinding

The process of electrochemical plane grinding for hard alloy ring applying to mechanic sealing is investigated by experiments, and the effects of the technical parameter such as the electric current density, electric voltage,the rotation rate of wheel and charging rate of the part, and the concentration and temperature of the electrolyte on the processing are analyzed. The results show that the faultiness in traditional working process can be surmounted, the operating cost may be decreased, and the working precise and surface quality of the hard alloy ring can be improved, the effect of the mirror grinding could be achieved in the best, by use of the electrochemical plane grinding process.
