ABSTRACT:
A grinding machine in which a workpiece, to have grinding operations carried out at different locations along the workpiece at different radii and at different angles, is mounted between centers on a slideway to present the locations on the workpiece to a motor driven grinding wheel mounted in a grinding head. The grinding head is mounted on a slideway to traverse the grinding wheel towards and away from the periphery of the workpiece. The grinding wheel is mounted on the slide for rotational adjustment about an axis extending tangential to the periphery of the grinding wheel at a location where the grinding wheel acts on the workpiece for adjustment of the angle of cut of the grinding wheel. Since the grinding wheel turns about an axis when its angle is adjusted, the position of an angle of cut is not otherwise varied by the angular adjustment of the grinding wheel. A control mechanism is provided for enabling the grinding wheel to be accurately preset to a number of predetermined angles to suit the workpiece to be ground. The grinding wheel head includes a dresser unit for dressing the grinding wheel and a mechanism for moving the dressing unit into engagement with the grinding wheel to dress the wheel and for restoring the grinding wheel with compensation for the amount of material removed by the dresser unit from the periphery of the grinding wheel.
