In a method and an apparatus for carrying out said method for grinding surfaces of workpieces with a grinding wheel, an electrode is provided which is disposed spaced apart from the grinding wheel, so that a gap is formed. An electrolytic cooling lubricant is introduced into the gap. By means of a power source, a current is generated which is conducted through the electrode, the electrolytic lubricant and the grinding wheel. An electrochemical conditioning of the grinding wheel thereby takes place, the wheel being thus sharpened. During the grinding operation, the forces exerted by the grinding wheel on the workpiece to be ground are measured, on the basis of which the electrochemical conditioning of the grinding wheel is controlled by changing the intensity of the said current using a computing and control device. The electrochemical conditioning of the grinding wheel can be carried out before, during and/or after the grinding operation, continuously or in intervals. The sharpness of the grinding wheel can thereby be kept constant over a long period of time. The machining time for the workpiece and the quality of the workpiece are optimal.
