Patent ID: 8091191

Claim:
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 ).
