ABSTRACT:
An improved ice skate blade sharpening system utilizing a powered rotating grinding wheel. The system has an adjustable guide for preventing canting and twisting of the blade as it is sharpened, and applies a constant cutting pressure to the edge irrespective of the force applied to the skate by the operator. The system also has a dressing mechanism utilizing a diamond-tipped stylus to maintain the proper curvature of the grinding wheel. The grinding wheel has a central plane perpendicular to the rotational axis, and is mounted to a drive shaft of an electric motor attached to a sliding block biased toward a first position by springs. The guide includes two opposing bearing surfaces spaced a distance apart and a mechanism for adjusting the distance between the bearing surfaces. The central plane of the grinding wheel lies between the bearing surfaces.
