ELID Grinding Based on the State Control of Passivating Films

Abstract:

The state of the passivating film is a key factor affecting ELID grinding. In the paper the state of the passivating film on the grinding wheel surface was characterized by the loop current, the strategies actively controlling the film state, discontinuous in-process electrolyzing and intermittent grinding were put forward, and the ELID grinding tests under the conditions of actively controlling of the film state and the traditional dynamic balance of the film state were respectively performed and contrasted with each other. It is indicated that by real-time monitoring of the film state with the loop current, the film state variation could be controlled to a narrow scope with the strategies of discontinuous in-process electrolyzing and intermittent grinding, as a result the ELID grinding kept at a fine quality and a high efficiency.
