Abstract
A multi-function grinding wheel truing mechanism that is capable of automatically imparting to the periphery of a grinding wheel either a combination radial and straight form, a radial form, a straight form, or a Gothic Arch form. A dresser unit housing swingably supports a turn post carrier which is normally biased to a first position by a spring. A turn post carrying a main diamond for dressing the periphery of a grinding wheel is rotatably supported on the turn post carrier. A single drive means is carried on the turn post carrier for moving the main diamond through a dressing path, and to accomplish all functions, including the automatic retraction of the main diamond at the end of the truing path and the automatic extension of the main diamond at the end of the return path. A cam means is operatively mounted on the turn post carrier for providing a combined rotary and swinging motion for moving the main diamond in a straight line dressing path, and for carrying out the dressing of a Gothic Arch form. A pair of side diamonds are provided for reducing the thickness of the grinding wheel during the time when the main diamond is imparting the form to the periphery of the grinding …
