Grinding disc and method for grinding planar bevels on glass sheets in particular on glass ceramic sheets

摘要

A bevel grinding disc comprising a cup-shaped grinding disc body (118) with a central mounting drilling (111) is disclosed, the cup edge (112) of which is embodied as a grinding ring (113). Within the interior of the cup (115) a second grinding ring (116) is concentrically arranged, which on grinding planar bevels on glass sheets, in particular, glass ceramic sheets (1), supports the forming bevel (3). Rounded run-in corners and run-out corners on the ends of the ridge (4) are thus avoided.
