ABSTRACT:
Machine comprising a main frame (1), machine bed (2), headstock (3) and tailstock (4) with means (17, 18) for mounting of the work for rotation about a work axis (C2), the means being disposed on the machine bed, with the headstock being movable in a direction (Z-axis) parallel to the work axis (C2). The machine also includes a slide system supported by the main frame (1) comprising two controlled-drive slides (7, 10), of which one (10) is displaceable in a direction (Y-axis) perpendicular to the work axis (C2), and the other (7) in a direction (X-axis) perpendicular to the Y and Z axes. Further included is a cradle (12) supported by the slide system (7, 10) and holding a tool head (13) for angular setting about an axis (A) perpendicular to the work axis (C2), the tool head being disposed between the headstock and tailstock. An internal gear tool is mounted in the tool head (13) for rotation about a tool axis (C1), with a controlled relative movement being provided in the Z-direction between the tool and the work. The inventive machine is characterized by the inclusion of a first horizontal slide (5) arranged on the main frame and movable in the Z-direction, the first horizontal slide (5) supporting a vertical slide (7) arranged for displacement in the X-direction. The vertical slide (7) supports a second horizontal slide (10), movable in the Y-direction, and the second horizontal slide (10) supports the cradle accommodating the tool head in a manner swivelable about the A-axis parallel to the X-direction. The tailstock is arranged fixedly on the machine bed.
