Complete machining center and method

A complete machining center comprising:

• a horizontal machine bed (1) having a vertical-axis trunnion (2) pivotally mounted for rotation about the vertical axis proximate a first-end portion (3) of the machine bed (1) and a traveling tool column (4) having horizontal X and Y travel proximate a second-end portion (5) of the horizontal machine bed (1);
• the traveling tool column (4) being positioned vertically on a compound slide (6) having X-axis linear travel with the X-axis travel selectively actuated by an X-axis motor (28) and by Y-axis cross travel with the Y-axis travel selectively actuated by a Y-axis motor (29);
• the vertical-axis trunnion (2) having thereon a work-piece holder (9) rotatable about a horizontal axis by a work-piece rotator (10);
• the vertical-axis trunnion (2) being rotatable about the vertical axis by a trunnion rotation-control motor (23) positioned on the vertical-axis trunnion (2) for selectively fixed and rotational positioning of a work piece (11) with the vertical-axis trunnion (2) for selective horizontal access to the work piece (11) by a selected cutting tool (12) attachable to a tool positioner (13) on the traveling tool column (4) and;
• the tool positioner (13) being moveable vertically in a Z-axis travel on the traveling tool column (4) by a Z-axis motor (30).
