Abstract
A turning boring head or the like has a tool, designed for radial adjustment, and whose tool support is able to undergo feed motion, using liquid power into a position dependent on the desired size of the bore being machined. The bore rod body has not only a pressure medium powered tool support designed for fine positioning of the fine-adjustment cutting tool, but furthermore at least one further tool support for a further cutting tool.
Claims6
A boring head having a boring axis and at least one bit disposed on the boring head for feed radially relative to said axis, the boring head having at least one elastic deformable bit holder provided for feed by means of at least one pressure piece which is powered by a controllable pressure medium dependent on the desired value of a bore diameter, said pressure piece comprising a feed piston movably mounted in a feed cylinder disposed transversely to said axis, said feed piston being operated by a pressurized liquid contained in a hydraulic cylinder and a hydraulic line interconnecting said hydraulic cylinder and said feed cylinder, a hydraulic piston of a first diameter movable in said hydraulic cylinder for pressurizing said liquid, a pneumatic piston of a second diameter greater than said first diameter being coupled with said hydraulic piston and working in a pneumatic cylinder which is connected with a pneumatic signal producer.
