Automatic lathe

An automatically operated lathe comprising:

• a lathe bed;
• a first spindle installed on said lathe bed and including an axis of rotation;
• a first tool rest installed on said lathe bed and capable of holding a plurality of tools in a parallel arrangement;
• a second tool rest installed on said lathe bed and capable of holding a plurality of tools in parallel arrangements along a first row and a second row exhibiting mutually different nose orientations;
• a second spindle installed on said lathe bed, including an axis of rotation parallel to said axis of rotation of said first spindle, and capable of being located facing said first spindle;
• a first spindle drive mechanism for linearly moving said first spindle along a first control axis parallel to said axis of rotation of said first spindle;
• a first tool rest drive mechanism for linearly moving said first tool rest along a second control axis perpendicular to said first control axis;
• a second tool rest drive mechanism for linearly moving said second tool rest along a third control axis perpendicular to said first control axis and a fourth control axis parallel to said first control axis;
• a second spindle drive mechanism for linearly moving said second spindle along a fifth control axis parallel to said third control axis and a sixth control axis parallel to said first control axis;
• and
• a control unit for controlling said first spindle drive mechanism, said first tool rest drive mechanism, said second tool rest drive mechanism, and said second spindle drive mechanism to enable a first machining work in connection with said first spindle by a desired tool selected in said first tool rest, a second machining work in connection with said first spindle by a desired tool selected in the first row of said second tool rest, and a third machining work in connection with said second spindle by a desired tool selected in the second row of said second tool rest to be simultaneously performed.
