Abstract (en)

[origin: DE19801377A1] The grindstone (20) has a stop surface (8) at each of two opposite flat sides (I, II). There are two circumferential grooves (13, 14) in the grindstone, one in each of the two stop surfaces. Both the circumferential grooves are at the same spacing (X) from their respective stop surfaces. The grindstone grinds the edges of glass disks (11) with cooling fluid supplied to the grinding point (18) while the grindstone has one of its stop surfaces against a counter-surface (7) on the grinding spindle.
