ABSTRACT:
The turning head comprises a support member (1) which is to be secured to the spindle of a machine tool. The support member (1) has a radially adjustable slider (4) which carries a tool (5). An adjusting rod (7) is displaceable coaxially with respect to the support member (1) and acts on at least one helically toothed rack (8) which is axially movable in the support member (1). Arranged on the slider (4) is a toothed bar (10) which extends in the direction of movement thereof and whose inclined teeth (10a) mesh with those of the rack (8) and are inclined at the same angle (.beta.) as the teeth of the rack (8), with respect to the axis of rotation of the support member (1). Provided on the slider (4) is an additional toothed bar (11) which extends in the direction of movement (V) of the slider (4) and which co-operates with an additional rack (15) which is axially movable in the support member (1) and which is braced against the support member (1) or the adjusting rod (7) or a member (7a) which is rigidly connected thereto, with the interpositioning of a prestressed spring assembly (16) in such a way that the spring assembly (16) applies to the slider (4) a force (P) which is directed radially inwardly towards the axis of rotation (A--A).
