When there is no standard sprocket cutter and a single piece produces a sprocket, a straight circular arc-shaped face tooth shape can be used (Fig. 1). Generally, when machining the sprocket with a slotting machine or a milling machine, the toothed line should be drawn on the sprocket blank first, so we use the dividing head to draw the toothed auxiliary line on the platform first, and then draw the tooth shape directly on the tooth blank. The effect is better.
