Abstract
A cup-shaped grinding wheel having an abrasive inner rim is brought into grinding contact with a tooth of a circular saw. The angle of attack of the grinding wheel is such that it imparts a second surface to the face of the saw tooth. The second generated surface has a continuous curved contour and a more negative average rake angle than the remaining portion of the face of said tooth. The apparatus and method are especially adapted to grinding the carbide tipped teeth of steel cutting saws but this technique may be used on other saw blades. Movements of the machine elements are automatically governed by a programmed electronic unit which, in turn, controls a system of hydraulic pistons.
