Abstract
Best described in the object of the main patent No. 300554, that is, in a device for fine drilling with a spindle bushing driven axially displaceable in a guide bore of the housing of the device, bushing that is centered virtually no slack in the guiding bore by means of a plunger-like guiding part, provided with a polygonal profile, as well as by means of the pressure of a circulating agent, with a centering action, and in the end part of which on the side of the tool, which it has a smaller diameter than the guide part, the spindle of the tool is supported, rotatably driven, so that it has no play and can not be moved axially, characterized in that the spindle of the bushing, mounted with clearance in the guide bore of the housing, which is provided with a polygonal profile corresponding to the polygonal profile of the guide part of the bushing, is provided, for its centering in the guiding bore. a, of chambers or pressure bags provided in its periphery and which are fed with a circulating agent that is under overpressure.
