The invention concerns a facing-tool head with a main body (10) which can be attached to a machine spindle, a work slide (14) which can be moved along the main body (10) essentially at right angles to the axis (12) of the spindle and which has a tool-holder with a fixing mechanism (26) to hold a tool in place, and a mechanism for adjusting the work slide (14). This adjustment mechanism includes a central, longitudinally movable adjusting rod (18) which passes through the hollow machine spindle (44) into the main body (10) and gearing means (20) which translate the longitudinal motion of the actuator rod into the transverse motion of the work slide (14). In order to ensure sufficient application of force between the adjusting rod (18) and the work slide (14), and hence suitable sliding characteristics and high adjustment precision, the invention proposes that the end of the adjusting rod (18) nearest the work slide is fitted with two off-center gear rods (20) mounted diametrically opposite each other in the main body (10) with their axes parallel to that of the main body, the gear rods having helical toothing (54) facing essentially in towards the interior of the main body and engaging with matching helical toothing (56) on the work slide (14) facing radially outwards.
A tool head, comprising a body adapted to be fastened on a hollow machine spindle of a machine tool, the machine spindle defining a spindle axis, at least one working slide displaceably mounted on the body, the working slide being displaceable essentially transversely to the spindle axis and having oblique, radially outwardly oriented toothing arrangement and at least one tool carrier, the tool carrier having a clamping mechanism for clamping at least one of a cutting tool and a tool holder thereto, an adjustment mechanism which can be actuated from the machine tool having an axially displaceable, hollow adjusting rod and gear mechanisms the adjusting rod being received centrally in the body and extending through the machine spindle, the gear mechanism converting the axial movement of the adjusting rod into the transverse movement of the working slide, an end of the adjusting rod near the slide supporting two off-center gear rods, the gear rods being located diametrically opposite one another, being aligned in an axis-parallel manner, being guided axially in the body and having an oblique toothing arrangement, the toothing arrangement of the gear rods being oriented essentially radially towards the body interior and being engaged with the complementary toothing arrangement of the at least one working slide.
