ABSTRACT:
A diamond point type dressing tool is mounted in a control head assembly capable of producing horizontal and vertical movements of the tool either independently or simultaneously to reproduce from a remotely disposed associated template any desired contour of angles and radii on the peripheral edge of a grinding wheel. A tracing rod, snugly but slidably journalled through a fulcrum support, has a tracing end adapted for manual movement over the profile of the template and a control end operatively associated with the control head for reproducing the template profile in the movement of the dressing tool. The fulcrum support is fixed against lateral or vertical movement but has the capability of turning in place as the orientation of the axis of the rod is changed during movement over the profile. In either the horizontal or vertical movement of the control end of the rod, slidable movement of the rod through the fulcrum support serves to keep constant the distance between parallel lines through the axis of the fulcrum support and the control end of the rod. The ratio of movement of the rod control end and the tracing rod end due to the fulcrum support together with a corresponding ratio of the template profile relative to the dimensions of the edge of the wheel may be 1:1 or greater and different selected corresponding ratios are obtainable by appropriate adjustments.
