NC turret lathe comprising a tool turret rotatable about an indexing axis and mounted for rotation in a turret slide displaceable in a direction parallel to the indexing axis, also comprising a turret indexing drive monitored by a control mechanism for rotating the tool turret, and a slide drive monitored by a control mechanism for displacing the turret slide. In order to decrease the expenditure required to index the tool turret, the slide drive also constitutes the turret indexing drive, and the slide drive control also serves to monitor the turrent indexing drive. An actuatable coupling is provided between the slide drive and the turret to prevent undesired rotation of the turret when it is only to be slidably displaced. |
