ABSTRACT:
An improved truing and dressing assembly and associated thru-feed centerless grinding machine is provided which effectively shapes the outer surface of a regulating wheel so as to allow the regulating wheel to follow the profile of the workpiece during grinding thereby avoiding interference between the regulating wheel and the workpiece outer surface thereby resulting in improved high precision grinding. The truing and dressing assembly of the present invention includes a truing wheel mounted on one side of the regulating wheel opposite the side on which the workpiece and workpiece support are mounted. The truing wheel is designed with an outer surface having a radius of curvature equal to the radius of curvature of the outer surface of the final ground workpiece. In addition, the truing wheel and workpiece are positioned at the same height above a reference plane extending through the rotational axis of the grinding wheel. This set-up arrangement permits the truing wheel to form an optimum regulating wheel profile which does not interfere with the outer surface of the workpiece during grinding thereby achieving optimum grinding operations while minimizing the cost and time required to set-up the machine.
