An automatic grinding machine for cleaning castings, including a machine stand, supporting mutually adjustable clamping or holding devices for processing a casting, and further including a tool holder, on which a grinding and/or cutting-off disk is adjustable with respect to the casting via a sliding device supported on a machine support, permits non-contact, precise generation of a control signal. The clamping devices are electrically insulated from the machine stand, and the grinding and/or cutting-off disk is electrically insulated from the tool holder. The grinding and/or cutting-disk is electrically conductive. The grinding and/or cutting-off disk and the clamping devices, including the casting held therebetween, are series-connected to a regulable high-tension generator and an ignition current evaluating switching unit, which supplies the control signal.
