Abstract: The invention involves a tool head 10, which can be rotated around an axis of rotation 24, with a tool-holding fixture 14, 16 for a tool 20 having a cutting edge 18 and with equipment 38, 40, 44 for adjustment of the radial position of the tool cutting edge 18 with regard to the axis of rotation 24. The invention distinguishes itself by the fact that the tool-holding fixture is divided up into a base element 14, which is supported in a first bearing system 40 in a carrier sleeve 44 so as to be able to rotate around the axis of rotation 24, and a tool-holding element 16, which is supported in a second bearing system 38 in the carrier sleeve 44 so as to be able to rotate around an eccentric axis 42 that is positioned in an eccentric fashion, as well as in parallel to, the axis of rotation 24.

Abstract: A tool head for the precision cutting of a surface of a rotating workpiece has a cutting tool which is movable in opposition to the force of a restoring spring from an initial position into an operating position with respect to the workpiece via an actuating drive. The actuating drive is formed by a translatorily movable driving element and a transfer element which converts the driving movement into an adjusting movement. The driving element used for adjusting the cutting tool from the initial position to a machining position is formed by an expansion bar actuated by magnetostrictive principles.

Abstract: A fine adjustment device for turning tool bits in the form of a pneumatic/hydraulic converter for converting of control signals into proportional actuating or adjusting forces with a combination of an oil pump and pneumatically controlled overflow valve, whose outlet pressure is adjustable with the help of control air.

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.

Abstract: A pressure transducer formed as a three-dimensional body is rendered flexible in order to permit fine adjustment of a machine tool seat formed thereon by the formation of holes and slits in the transducer body which cause portions of the body to operate as spring-like webs. An expansion box is located within the transducer and a pressure transmitter separate therefrom is connected thereto to enable pressure from the transmitter to be applied to the expansion box to cause flexing of the transducer body and fine adjustment of the position of the tool seat. Because of the particular arrangement of the holes and slits in the transducer body, the tool seat is able to be moved parallel to itself during the adjustment process.
