An improved electrochemical grinding wheel electrode consisting essentially of electrically conductive abrasive grains bonded together with an essentially nonconductive bonding matrix. The abrasive grains are admixed with an amount of 10 to 30% by volume of the bonding matrix and sintered together to form the porous, homogeneous electrode body, e.g. in the form of a wheel, having a specific resistivity not greater than 100 ohm-cm, preferably between 0.1 and 10 ohm-cm.
