ABSTRACT:
A tool is described for boring spherically curved inner surfaces consisting of a main body which rotates about its longitudinal axis during the boring operation. A swivel housing is mounted on an axle bolt in the main body and can thus be swiveled about an axis at right angles to the longitudinal axis. The swivel motion is produced with the aid of a linkage arrangement provided in the tool. A cutting tool holder is guided for longitudinal displacement in the swivel housing at right angles to the axle bolt. The cutting tool holder is supported lateral wedge surfaces on a mating wedge surface of the axle bolt and extends with a shank part through the axle bolt. With the aid of a compression spring and an adjusting screw, the axle bolt can be displaced in the longitudinal direction relative to the cutting tool holder to adjust the radial spacing of the cutter from the axle bolt by the mating wedge surface.
