  • Automatic lathe
    Patent number: 7117774
    Abstract: An automatic lathe (10) is provided with a first spindle (14) having an axis of rotation (14a), a first tool rest (18) capable of holding a plurality of tools (22) in a parallel arrangement, a second tool rest (20) capable of holding a plurality of tools (22) in parallel arrangements in a first row and second row exhibiting mutually different nose orientations, and a second spindle (16) 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 (12). 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.
