Abstract
In a method of producing a beveled peripheral profile on a semiconductor disk (1), the peripheral profile is ground by an obliquely-arranged grinding disk (7). The centering of the semiconductor disk (1) in the clamping device, consisting of clamping heads (3, 6), preferably occurs via a bonded-on molybdenum disk (2), which runs on a guide disk (9). The employment of a diamond grinding disk with suitable grains and binder is particularly appropriate.
