Which wheel is used to cut a bevel on the lens during edging?

Explanation:
The bevel that helps a lens seat securely in a frame is created by the bevel wheel. This wheel is specifically shaped to cut an angled, sloped edge—the bevel—that sits around the lens periphery. While the grinding wheel roughs and sizes the edge and the polishing wheel finishes it to a smooth surface, the bevel wheel provides the actual beveled contour needed for proper frame fit. The other wheel types serve different finishing steps, so they don’t produce the angled edge that the bevel wheel creates.
