Vertical turning-milling complex machining center

A vertical turning and milling complex machining center, comprising:

• a bed body;
• two stand columns, which extend with longitudinal axes thereof vertical in a Z-axis direction, and are each affixed to a respective end of the bed body at left and right sides of the bed body;
• two X-axis side portion supporting linear guide rails and two X-axis guide screws, which are respectively disposed at the left and right sides of the bed body and extend with a respective longitudinal axis thereof in an X-axis direction perpendicular to the Z-axis direction, wherein X-axis drive motors are each disposed at a respective end portion of a respective one of the X-axis guide screws;
• a rotating table, which is located between the two X-axis side portion supporting linear guide rails and is driven directly by a first external rotor torque motor located below a work table main body of the rotating table;
• a transverse saddle that supports the rotating table and is connected to the two X-axis guide screws, the two X-axis guide screws providing for reciprocating movement of the transverse saddle and the rotating table along the X-axis;
• the transverse saddle further comprising a middle part that engages an X-axis middle portion supporting linear guide rail, the middle part being located at a midpoint of the rotating table in a Y-axis direction perpendicular to the X and Z-axes, the X-axis middle portion supporting linear guide rail being located on the bed body at a midpoint between the two X-axis side portion supporting linear guide rails in the Y-axis direction;
• two first Z-axis side portion supporting linear guide rails and two first Z-axis guide screws, which are each disposed on a respective one of the two stand columns and extend with a respective longitudinal axis thereof in the Z-axis direction, wherein a crossbeam is erected between the two first Z-axis side portion supporting linear guide rails and is connected to the two first Z-axis guide screws for vertically reciprocating movement along the Z-axis;
• first Z-axis drive motors are each disposed at a respective end portion of a respective one of the Z-axis guide screws;
• two Y-axis linear guide rails and a Y-axis guide screw, which extend along the crossbeam with a respective longitudinal axis thereof in the Y-axis direction, wherein a transverse sliding table, which is connected to the Y-axis guide screw for reciprocating movement along the Y-axis, is disposed on the crossbeam;
• a Y-axis drive motor is disposed at an end portion of the Y-axis guide screw;
• and
• the transverse sliding table is provided with a single pivotable pendulum milling head component which is driven directly by a second external rotor torque motor.
