ABSTRACT:
The protective cutoff device includes a cutoff control and a cutoff valve system connected to an automatic position control which is present anyway in the gear wheel grinding machine serving for topological flank correction grinding and to an adjusting cylinder, respectively. As a result, the grinding wheel is effectively disengaged from the tooth flank in the process of being ground in the event of electric power failure and/or pressure failure or an undesirable pressure drop or upon the occurrence of any other disturbance or malfunction of the grinding wheel. Therefore one side of the adjusting cylinder is connected to a return line and the grinding wheel carrier or support is displaced against a stationary stop by a force or pressure accumulator.
