Abstract
A device for grinding saw blades, both hand saws and circular saws so that a predetermined tooth profile is obtained, utilizes a grinding head that moves in one plane and moves the saw in a second plane. The device comprises a saw blade mount, an indexing system for indexing a saw tooth to move in a first plane, a grinding head to grind a saw tooth, a grinding head travel arrangement to move the grinding head in a second plane, the second plane being at an angle of about 35.degree. from the perpendicular of the first plane, and a control system for controlling movement of the saw blade in the first plane and the grinding head in the second plane to ensure a predetermined saw tooth profile is ground.
