An automatic turning machine which employs two discrete turning units and a transfer mechanism serving to deliver semifinished workpieces from the first unit to the second unit. The first unit employs a rotary work spindle which cooperates with several cross slides and, if necessary, with a turret or tool spindle for tools whereby the tools which are held by the cross slides and/or turret and tool slide treat the workpiece while the latter rotates with the work spindle. The second unit employs an indexible carrier with several sets of equidistant jaws which transport workpieces, received from the work spindle by way of the transfer mechanism, past several working stations at each of which a workpiece held by the respective jaws can be treated by one or more rotary tools which are mounted in tool spindles forming part of assemblies mounted for movement radially, in parallelism with or at another angle relative to the axis of the carrier. |
