Abstract
An experimental apparatus was constructed to study electrolytic dressing applied to bronze bonded diamond grinding wheels. Experiments were performed to explore the qualitative micro structural features of the dressing, and to evaluate the quantitative rates of fllm formation and wheel recession. EDM and de power supplies were used to drive the electrolysis. For one choice of the relevant process parameters (open circuit electrode voltage, electrode gap size, electrolyte, and pulsed voltage duty cycle), it was found that a film extended both out of and into the wheel surface. The rate of growth of the film into the wheel was approximately constant (1.5 nm/s). It was found that successful application of electrolytic dressing methods for bronze bonded grinding wheels in industry will depend on the wear characteristics of this film.
