A new regulating wheel truing method for through-feed centerless grinding

A new regulating, wheel truing method for through-feed centerless grinding is presented. In conventional regulating wheel truing systems, a single-poi nt diamond tool is traversed across the regulating wheel in a straight line . The interference between the regulating M heel and workpiece exists. This interference problem, a main source of Error in precision through-feed cen terless grinding, is due to the radius of curvature of the regulating wheel and workpiece. A new concept for regulating wheel truing is developed to e liminate the interference a problem. In this new. truing system, the rotary diamond truing tool has the same size as the finished workpiece, locates a t the same center-height of the workpiece, and moves across the regulating wheel in the direction parallel to axes of workpiece and grinding wheel. A mathematical model is developed to calculate the surface profile for the re gulating contact and to study the curved line of contact between, workpiece and regulating wheel. An example is used to illustrate the model and to de monstrate that the interference between regulating wheel and workpiece has been eliminated.
