An apparatus is provided for converting a pressurized air operating impulse to a hydraulic operating impulse, especially for a precision grinding machine. The apparatus comprises at least one tool support, a compressed air control system for a plurality of adjusting or positioning piston cylinder devices, and a cooling and washing fluid system. The tool support has a fed piston cylinder device which is provided with two pressurized medium inlets, one of these inlets being for the feeding and pressing on motion, the other one being for the take off motion. Two regulating chambers mounted vertically are provided with connecting members for the pressurized medium inlets of the fed piston cylinder device in the lower portion of the regulating chambers. Further, a flow control device for feeding of wash and cooling fluid into the regulating chamber with a level control device and an controlling air connector are present in each of the regulating chambers above the level of the wash and cooling fluid in the regulating chamber which is controlled by the level control device. The controlling and operating impulse of the pressurized air control system acts on the level of the controlling wash and cooling fluid in the regulating chamber.
