Abstract

The circular grinding disk consists of an abrasive body, which is mounted via a metal hub on an axle or shaft. The grinding disk forms an electrode which is capable of being connected to a high-tension generator, the counter-electrode thereof being a casting, between which, upon approach, an arc is ignited, which generates a control signal. For this purpose, the grinding disk is electrically-conductive over the entire extent thereof.
