A study on the mirror-like grinding of die steel with optimum in-process electrolytic dressing

In recent years, grinding techniques for the precision machining of brittle materials used in die, mold and optical parts have been improved by using super-abrasive wheels and precision grinding machines. The completion of the optimum dressing of a super-abrasive wheel makes possible the effective precision grinding of die steel STD-11. However, the present dressing system cannot have control of the optimum dressing of the super-abrasive wheel. In this study, a new system and the grinding mechanism of optimum in-process electrolytic dressing are proposed. This system can carry out the optimum in-process dressing of a super-abrasive wheel. Therefore, optimum in-process electrolytic dressing is a good method to for obtaining the efficient and mirror-like grinding of STD-11.
