Abstract

The automatic grinding machine for cleaning castings, having a machine column (10) carrying locking means (5, 6) for a casting (1) to be treated, which locking means (5, 6) can be adjusted towards one another and together, and a tool holder (3) which carries a grinding and/or a cut-off wheel (2) and is supported on a machine block (11) in such a way that it can be set against the casting (1) via slide means (4), permits contactless, precise production of a control signal owing to the fact that the locking means (5, 6) are electrically insulated from the machine column (10) via insulation means (12) and the grinding and/or cut-off wheel (2) is electrically insulated from the tool holder (3) via insulation means (13), that the grinding and/or cut-off wheel (2) is designed to be electrically conductive, and that the grinding and/or cut-off wheel (2) and the locking means (5, 6) and the casting (1) clamped between the latter are connected in series with a controllable high-voltage generator (20) and an ignition-current analysing circuit (21) supplying a control signal (22). <IMAGE>
