ECDM (Electro Chemical Discharge Machining), a new method for trueing and dressing of metal-bonded diamond grinding tools

Metal bonded grinding tools cannot be processed efficiently and economically by means of traditional conditioning technologies and are therefore rarely used. A new hybrid technology that combines EDM and ECM called ECDM, allows both the trueing and dressing of these grinding tools in just one step. Therefore ECDM is the ideal technology for trueing and dressing of metal bonded diamond tools and hence for the grinding of new cutting materials (Cermets, Ceramics, PCD). This new method has been applied successfully on a centerless grinding machine.
