ABSTRACT:
A diamond point type dressing tool with means for adjustment to dead center within a tolerance of .+-.0.0001" is mounted to a control head assembly capable of producing horizontal, rotary 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 support ball, 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 and for rotating the diamond point where necessary on the profile. The ball support is seated in the control head and is fixed against lateral or vertical movement but has the capablility 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 ball support serves to keep constant the distance between parallel lines through the axis of the ball 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 ball support together with a corresponding ratio of the template profile relative to the dimensions of the edge of the wheel may be designed for 1:1 or greater and different selected corresponding ratios such as 5:1 or 10:1 for extreme accuracy may be provided in the design of the tool.
