In the paper the electrodischarge and electrochemical dressing method of super hard grinding wheels using segmental tool electrode and low concentration of electrolytes has been presented. Also the investigation stand for dressing has been depicted. The experimental results concerned forming of cutting surface of grinding wheels (CSGW) in two different processes: electrodischarge profiling and electrochemical dressing. The obtained results confirmed usefulness of both of these processes in forming macro- and microgeometry of CSGW, reduction of geometrical deviations and form dressing of super hard grinding wheels with metal bond. Potential application of electrochemical and electrodischarge methods using diluted solutions of electrolytes for dressing of grinding wheels has been presented. The hybrid system of electrodischarge and electrochemical grinding wheels dressing has been proposed.
Rational exploitation of super hard grinding wheels with metal bond requires estimation of constituent costs of grinding process and dressing of grinding wheels. In the article the method of electrochemical dressing of super hard grinding wheels and economical analysis of electrochemical dressing of these kind of grinding wheels consisted in assessment of selected costs of this process has been presented. Also analysis of costs of the grinding process has been depicted. Obtained relationships allowed us to estimate contribution of respective component of costs of grinding process using super hard grinding wheels and are basis for their optimization.
