ABSTRACT:
The rotary transfer machine for machining a workpiece using fixed-cycle control has a centrally disposed rotary indexing table which is driven according to a fixed cycle, can rotate about a vertical axis and at the outer circumference of which a plurality of clamping means for holding a workpiece are disposed radially at a spacing from one another, and a plurality of machining units for machining the workpieces, which units are disposed around the outer circumference of the rotary table such that they lie substantially opposite corresponding clamping means in an indexed position of the rotary indexing table. In order to shorten the change-over time for new parts which are to be finished and enable parts to be produced with a high degree of precision, at least one machining unit comprises a main clamping device for holding a workpiece which can travel in the direction of the longitudinal axis of the corresponding clamping means and rotate about a rotational axis which is coaxial with or parallel to the longitudinal axis of the clamping means, and an auxiliary carrier device with a toolholder for a tool for manipulating or machining the workpiece. The movements of the main clamping device and of the auxiliary carrier device are effected under CNC control and can therefore be programmed.
