What is the primary purpose of the bevel wheel in lens edging?

Explanation:
The bevel wheel’s job is to cut a beveled edge around the lens. This angled edge lets the lens sit securely in the frame’s groove or channel, distributes edge stress, and reduces the chance of chipping or snagging when the lens is mounted. After beveling, the edge is typically finished with polishing to smooth it, but the key purpose of the bevel wheel is to create that sloped edge. It isn’t used to polish the surface, trim the frame, or drill holes in the lens.
