Abstract
A lathe comprises two turrets each arranged on a compound slide system. The turrets are mounted on sides of the two compound slide systems facing each other and have indexing axes extending parallel or at a slight incline to the work spindle axis of the lathe. To reduce the danger of collisions between the two turrets and to enable the two turret bodies to be moved close together, the turret body located on the headstock side is smaller and has less stations than the other turret body with the result that the circles described by the tool cutting edges during rotation of the two turrets are smaller in the case of one turret than in the other.
