Abstract

Abstract A device and method for contouring and sharpening an ice skate blade. The device uses a fixture for holding the ice skate. The fixture employs retractable depending cam rollers to be guided by cam templates recessed into the top surface of the table of the machine. The cam templates are coverable when not in use, thus increasing the usefulness of the top surface of the table. The grinding wheel is movable into and away from the fixture. One of the cam rollers is mounted to an eccentric wheel for pitching the ice skate blade in relation to the grinding wheel. The method comprises the steps of clamping a skate into the fixture, retractably depending or lowering the cam rollers to engage the cam templates in the table of the machine, adjusting the cam roller by operating the eccentric to achieve the desired pitch, moving the grinding wheel to the fixture holding the ice skate and contouring or sharpening the ice skate.
