Abstract:
1. An apparatus comprising: a rotatable abrasive surface affixed for rotation about a central shaft; a tool support structure coupled to the abrasive surface and structurally configured to contactingly support a body portion of a tool while a cutting surface of the tool is presented against the abrasive surface during a sharpening operation; and a cooling mechanism which operates to actively draw heat generated during the sharpening operation through the body portion of the tool and the tool support structure to reduce a temperature of the tool, the cooling mechanism utilizing a cooling fluid which passes adjacent the tool support structure to remove heat from the tool and the tool support structure through conduction, the cooling fluid characterized as ambient air, the tool support structure characterized as a heat sink with a base portion having a tool support surface configured to contactingly support the tool and a plurality of cooling fins which extend from the base portion opposite the tool support surface, the cooling mechanism comprising a rotatable impeller coupled to the central shaft for rotation therewith to direct the ambient air across the cooling fins.
