Abstract:

According to the technological indexes for smooth surface of the hard brittle materials, for example, ceramics, glass, crystallines, special ELID grinding equipment for MM7120A precision surface grinder has been developed.On the basis of the above mentioned experimental environment,experimental investigations on ELID techniques of cast iron bonded microabrasive wheel have been carried out.Main research achievements are as follows:①The influential relationship of electrolytic parameters on dressing result has been established;②Double effect character (namely,microtrueing and precision dressing) of ELID diamond wheel has been proposed;③Eletrolytic film has a very important role on dressing quality and smooth ground surface.

Key words: cast-iron bonded diamond wheel, microa brasive, electrolytic in-process dressing
