Description: |
| Abstract:
A wheel or tool dresser for precisely shaping grinding wheels with arcuate and angle shapes is provided with stops which may be set to precise limits to dress the wheel at determined angles. The dresser includes a base which carries nested upper and lower swivel rings and a brake or drag disposed to engage the inner surface of the lower ring. The pedestal is rotatably supported on a plurality of balls and may include sliding surfaces with cam portions which compensate for the arc of swing of the dressing point. A vibration dampening member in the form of a spring supported weight may be provided in the pedestal. The upper and lower swivel rings are clamped by means of a thumb screw and include stops which are engaged by adjustable screws carried by the pedestal, the adjusting of the screws providing a precise setting of the displacement of the pedestal.
