Conditioning a Diamond-Grit Cup-Wheel for Electrochemical Grinding

  • M. M. Sfantsikopoulos

The paper discusses truing, dressing and cleaning of a diamond-grit cup-wheel by mechanical and electrochemical means. Particular emphasis is given to subsequent use for electrochemical grinding. Electrochemical truing is shown to offer no advantage over conventional methods except for fully retracting the metallic bond from the surface of the diamond grits. Similarly electrochemical dressing is shown to remove conductive products from the inter-grit spaces. Particularly advantageous wheel-wear characteristics are shown to exist during subsequent E.C.G. use. Invaluable features are further exhibited by in-process electrochemical cleaning, provided it is carried out prior to passive conditions arising.
