Abstract
The electrolytic in-process dressing grinding of ceramic balls was investigated on a magnetic fluid support grinding machine by using fine diamond grinding wheels SD16000 of both bronze bond and cast iron bond under different dressing currents in two different electrolytes. The experimental results showed that the grinding efficiency increased with the dressing current. However, the ground surface was roughened when the current increased to over 160 mA in the study. The bronze-bonded grinding wheel showed a higher dressing effectiveness than the cast iron-bonded grinding wheel in both tap water and the CG-7 solution. As an electrolyte, tap water was more effective than CG-7 solution in terms of the grinding efficiency improvement.
