In lens edging, which wheel is used specifically to create the bevel on the lens edge?

Explanation:
Creating a bevel on the lens edge is about shaping a sloped edge so the lens sits securely in the frame and resists chipping. The bevel wheel is specifically designed to cut and form that bevel along the whole edge, producing the angled edge that seats neatly in the frame’s groove. The grinding wheel handles the rough shaping of the edge, and the polishing wheel smooths and finishes the edge after beveling. The silver wheel isn’t used for forming the bevel in standard practice.
