Abstract
A cup-shaped wheel having an abrasive rim is employed to edge grind the teeth of a circular saw to an improved contour. The grinding wheel is carried by a slide means which brings the grinding wheel into contact with the teeth of the circular saw. The slide means is also adapted to accomodate a drive motor for rotating the grinding wheel. An adjustble mechanism is incorporated into the slide means to adjust the angle of attack of the grinding wheel. In this manner the contour of the working surface generated can be varied at will. Since only point or edge contact takes place between the abrasive rim and the tooth, the wheel is essentially self-dressing. The method and apparatus are specifically adapted to grinding the carbide tip teeth of steel cutting saw blades. The relative movement of the machine elements is automatically controlled by a programmed electronic unit which, in turn, controls a system of hydraulic pistons.
