  • Process and apparatus for grinding with electrolytic dressing
    Patent number: 8303799
    Abstract: A process for grinding workpieces is obtained which includes attaching honing stones to a tool, each of the honing stones including grinding particles and an electroconductive connection for fixing the grinding particles to each other; grinding the workpieces with the honing stones by applying a honing liquid having substantially no electroconductive property to a region between the workpiece and the honing stones, the workpieces being successively ground during a series of processing periods, while interposing non-processing periods between the processing periods, each of the workpieces being ground in one of the processing periods; and performing an electrolytic dressing with respect to the honing stones by using an electrode provided to face the honing stones with a space therebetween, a voltage being applied between the honing stones and an electrode in the presence of an electroconductive liquid in the space between the honing stones and the electrode, the electrolytic dressing being carried out during t
