Abstract
An automatic lathe () is provided with a first spindle () having an axis of rotation (), a first tool rest () capable of holding a plurality of tools () in a parallel arrangement, a second tool rest () capable of holding a plurality of tools () in parallel arrangements in a first row and second row exhibiting mutually different nose orientations, and a second spindle () having an axis of rotation parallel to the axis of rotation of the first spindle and capable of being located facing the first spindle, in such a manner as to be centrally carried on a lathe bed (). The first spindle can move linearly along a first control axis parallel to its axis of rotation. The first tool rest can move linearly along a second control axis perpendicular to the first control axis. The second tool rest can move linearly along a third control axis perpendicular to the first control axis and a fourth control axis parallel to the first control axis. The second spindle can move linearly along a fifth control axis parallel to the third control axis and a sixth control axis parallel to the first control axis. A control unit () enables simultaneous performance of first machining work relating to the first spindle by a desired tool selected at the first tool rest, second machining work relating to the first spindle by a desired tool selected from the first row at the second tool rest, and third machining work relating to the second spindle by a desired tool selected from the second row at the second tool rest.
