Abstract
The invention relates to a moving gantry machine having uprights that are movable relative to each other. The uprights are interconnected by a cross-member made up of two cross-member elements suitable for being moved relative to each other in the limit of a given maximum offset .DELTA. in the displacement direction of the uprights. The displacement of the uprights is controlled by respective independent drive systems X.sub.1 and X.sub.2 under numerical control within the limit of said offset. A third drive system X.sub.3 is provided for displacement between the cross-member elements and is under numerical control with the condition the displacement distance of drive system X.sub.1 +the displacement distance of drive system X.sub.3 =the displacement distance of drive system X.sub.2.
Claims2
A moving gantry machine comprising two uprights standing on a bench via parallel slides defining a longitudinal X axis, the displacement of said uprights along said X axis being controlled by respective drive systems X.sub.1 and X.sub.2 under numerical control, and a cross-member interconnecting said two uprights, said gantry being capable of carrying machining heads on each upright, which heads are suitable for being displaced along Y and Z axes,
- wherein the cross-member is made up of two cross-member elements carried by respective ones of the uprights and suitable for being moved relative to each other in the X direction within the limit of a given maximum offset .DELTA.;
- and
- wherein the drive systems X.sub.1 and X.sub.2 are independent of each other and are under numerical control within the limit of said offset .DELTA..
